Ponsel 3 G

Many of the new phones being offered by the big carriers are being advertised as being "3G" ready. The average mobile phone consumer often will not know what the third generation is or why it's important to them. To be a better informed consumer lets investigate exactly what it is.

What Is It?

3G stands for Third Generation and refers to the third generation of technology in the mobile industry. This generation follows 1G and 2G technology.

1G

The first real cell phones are considered to be 1G (First Generation). The networks for these early cell phones used analog signals. The phones used on the networks were big and clunky, with no abilities aside from voice.

2G

The technology categorized as 1G was in place up until the early 1990's, when it was then replaced by the 2G technology features. With 2G came a break away from the analog signals and a move towards the digital spectrum. 2G brought with it the introduction to providing multimedia content and increased bandwidth. A lot of the technologies classified as 2G are still being used in cell phones today.

2.5G

Before the complete rollout of 3G technologies, 2.5G was introduced. Primarily used as a marketing term, 2.5G is not an officially recognized technology; but it can be used to refer to the "in between" stage of moving away from 2G and moving completely into the 3G realm. 2.5G uses the existing 2G infrastructure while enabling some of the benefits of the 3G technologies, including increased multimedia abilities and improved data transfer speeds.

3G

The technologies that now qualify as the third generation include increased functionality of mobile phones; with increased speeds and bandwidth being the biggest appealing factors. Multimedia functionality on the networks also improves, by leaps and bounds, with the move to these new technologies.

While 3G capable phones are incredibly appealing to cell phone buyers they may find that not all of the functionality their phones are capable of available to them. Carriers in the US have yet to fully roll out their upgraded networks in all markets. AT&T is leading the market right now, with their networks being available in most major metropolitan markets; however the biggest AT&T seller, the iPhone, is not 3G capable. Apple has stated that a third generation version might be possible in the future when the networks are more widely available in the US.

T-Mobile is trailing behind AT&T when it comes to their network. Until recently, none of the third generation capable phones T-Mobile sold could have their full functionality used; simply because the infrastructure is not yet fully in place across the T-Mobile markets. T-Mobile has recently launched their new network in New York, allowing New York customers the ability to take advantage of the full functionality of their 3G capable phones.

3G will, soon, become the standard technology in the mobile industry; it is just up to the wireless carriers to ensure that they quickly meet the demands of their users who want to take advantage of the third generation technologies as soon as possible.

Teaching Children Astronomi

At certain times of the year and dependent upon where you live, hopefully you can be outside to enjoy the beautiful days as well as glorious night sky. After the long winter months, there will be plenty of opportunities to explore our outside world in relative comfort. When we look to the skies, most of us are amazed at its splendor but don't have a clue as to what we are looking for or at. So, when the weather permits, step outside and share in the expanse of the sky.

As parent and child begin their journey of the solar system, remember, it is suppose to be fun. There are so many stars in the sky that you might want to start simple and build your way. Astronomy for kids does not need to be confusing or intimidating. It can simply be fun and bonding!

Although the night sky is well mapped and extremely fascinating, it is also complex. To spark long-remembered conversations and moments to be shared, start with a few simple searches for planets that are visible to the naked-eye: Mercury, Venus, Mars, Jupiter, and Saturn.

Mercury is the closest planet to the sun. The best opportunity to observe Mercury is when it is at its highest point in the sky. Sometimes Mercury is visible in the evening. In this case you can start observing Mercury shortly after sunset but you will have less than an hour until the planet sets below the horizon. At other times Mercury is visible in the morning. You will be able to see Mercury at most an hour or so before sunrise and can observe it until the light from the rising sun drowns it out.

Venus is the second closest planet to the sun. Whenever Venus is visible, it is much brighter than anything in the sky, with the exception of the sun and moon.

Mars is the fourth closest planet to the sun. When Mars is bright, it is bright red; when it is dim, it is a pale pink (at such times it may be difficult to see any color at all). Mars goes from bright to dim back to bright every two years.

Jupiter is the fifth closest planet to the sun. Jupiter is the largest planet in the Solar System. Jupiter is lost in the Sun's glare. Nevertheless, it is out there, on the other side of the Sun from Earth and 580 million miles away from our planet. It returns to view in mid-January, low in the morning sky.

Saturn is the sixth planet from the sun. Saturn appears pale yellow to the naked eye. Although never appearing quite as bright as the other planets, it is still obvious when the position is found.

Mercury, Mars, Jupiter and Saturn are brighter than anything other than Venus, the sun or moon, Sirius and Canopus.

Once you have found, identified and possibly mapped the obvious, search deeper. You may find that you are enjoying the night sky as much as your child!

Fun Science Projects

We have a number of short Examples Of Science Fair Projects. In this short easy elementary science projects we are going to see some of the interesting things that happen because of the density of liquids. The density of and object has to do with how tightly packed the object is. Two objects can weigh the same but one is smaller than the other, the smaller one is packed more tightly and is therefore denser than the other object. These experiments are meant to make learning fun and are also very suitable for homeschoolers.

The floating egg experiment

What you will need for this easy elementary science project:

A container

Water

An egg

Salt

A spoon

This is what you have to do for this easy experiment:

Fill the container with enough water to cover the egg completely.

Carefully place the egg in the water.

What happens to the egg?

Make a note of what happens.

Start adding salt to the water and stirring it very carefully so as not to break the egg.

Keep on adding salt until your egg starts to float.

You will need quite a lot of salt, about 4 tablespoons full of salt per 1 ½ cup water to make the egg float.

Now you add water to your solution again until the egg start sinking again.

Keeping density in mind, try and explain what just happened.

If you worked carefully and did the experiment the right way your egg started rising because it became less dense than the water when you added the salt. When you added extra water, the water once again became less dense than the egg and the egg started sinking again.

This is one example of our easy elementary science projects, one of many examples we have of science fair projects.

Check out fun science projects. Thanks!

Learning Basic English

English has become the international language of business and will remain so for the foreseeable future. Whether it's a German project manager dealing with a French auto parts manufacturer or a Chinese software developer advising a Mexican medical center the intermediary language is English. So why exactly has English taken front stage when there are so many other languages spoken by a much greater number of people over much vaster regions? The answer lies in the in the simplicity of the grammatical structure of the English language at its most basic level. Unlike most other languages English doesn't use the genitive case for definitive articles. This means that every "thing" in English uses the pronoun "it" and the definite article "the".

In many other languages an object can be masculine, feminine or neutral and the gender of the object can affect the whole sentence. It can also change the endings of pronouns which can make learning the basics a little confusing. The same problems apply to adjectives, adverbs and then add pronunciation to the equation to top it off. And this is only dealing with European languages which stem from Latin, Greek and near eastern roots. When one looks at Chinese, Japanese, Arabic etc. then one can appreciate the difficulty of learning even the most basic structures of these languages.

Of course, there are also political, historical and economic reasons for English being the most used language when it comes to modern business but the fact that it is easy to get a grasp of Basic English has to be the most appealing advantage for non native speakers of English. Ironically, it is communication between the native English speaker and the non-native English speaker that tends to create the most problems. The reason for this is the tendency of the native English speaker to slip into colloquial speech, slang, idiomatic language, speak too quickly or a simple matter of harsh regional accents. But when two or more non-native English speakers communicate in Basic English it usually works out fine because nobody is out to impress and the ultimate goal is to simply understand and respond at a simple level. This is not to say that English doesn't have complexities, in fact at higher levels it can be just as difficult as any other language but as long as a learner uses the famous K.I.S.S. technique (Keep It Short And Simple) it is definitely the easiest language for global communication.

Cheking Your Speed Online

The speed of internet plays a vital role in surfing, downloading or uploading. Everyone is keen to know about the upload and download speed the internet service provider ISP is providing.
Nowadays when most of the dialup users have shifted to new services called Broadband T3 the speed is not a problem. The rates of the services are also being reduced and helping the end-user.
The speed is not always consistent and end-user always like to check the speed of the internet i.e. upload and download which in most cases is checked by uploading a file or downloading a file from some site.



Mengetahui Kecepatan koneksi internet


Ada berbagai cara untuk mengetahui seberapa besar kecepatan koneksi internet anda, berikut adalah cara-cara untuk mengetahui kecepatan internet anda :

Melalui test kecepatan via web.
Melalui software bandwitdh monitor yang diinstall terlebih dahulu pada komputer anda.
Melalui Multi Router Traffic Grapher (MRTG) yang biasanya diberikan oleh provider-provider internet yang menggunakan koneksi broadband seperti Channel-11.
Sebelum anda melakukan test kecepatan, penting bagi anda untuk perhatikan hal-hal berikut ini untuk memastikan hasil test anda lebih akurat :

Jika komputer anda berada pada suatu jaringan yang mana semua komputer terhubung ke internet maka pastikan bahwa komputer yang lain tidak melakukan aktifitas internet seperti download ataupun upload, jika perlu matikan semua komputer kecuali komputer yang akan anda pakai untuk melakukan test kecepatan.
Ada baiknya anda melakukan koneksi internet pada PC router atau server jika tidak memungkinkan untuk mematikan semua komputer pada jaringan anda, anda hanya tinggal menonaktifkan jaringan lokal sehingga hanya komputer server saja yang terhubung ke internet.
Pastikan komputer anda atau pada jaringan komputer anda bersih dari virus, spam atapun spyware yang dapat mengganggu traffic jaringan dan koneksi internet anda.

VIRUS AND SPYWARE REMOVAL

Is your internet connection running irritatingly slow? Is your web access turning on and off? Are there programs in your computer that do not work as well as they used to? Are there also pop-up images that annoyingly display on your screen every now and then?

These are the common symptoms that plague virus and spyware-infected computer systems. With the important role that computers now hold in this hi-tech society we live in, it is mandatory that you take care of your system and ensure its maximum potential and longevity. Your computer has become a helpful friend - one that does most of your work for you (and has made everything more convenient, too), so it is only fair that you repay it by defending it from harmful elements. For you to be able to do this, need to perform virus and spyware removal - and you need to perform this fast.


Mencegah dan Mengobati Virus


Untuk Mencegah dan mengobati virus ada 10 langkah yang perlu diperhatikan.
1. Update system operasi

Bukan rahasia, Microsoft Windows merupakan system operasi yang paling banyak dijangkiti virus. Ini bukan berarti Windows lebih jelek dari pada sistem operasi yang lain, tapi semata-mata karena Windows merupakan sistem operasi yang paling banyak dipergunakan orang. Bagi pembuat virus, ini sasaran empuk, karena tidak susah mencari target.

Microsoft belakangan semakin memperhatikan masalah ini. Terbukti dengan komitmen Microsoft untuk terus menambahkan fitur-fitur security sebagai patch atau upgrade versi. Tapi otomatis ini tidak akan menyelesaikan masalah bila anda tidak menginstall patch tersebut. Kalau anda terhubung ke Internet, anda bisa mengaktifkan fitur Live Update yang otomatis akan mengupdate sistem operasi anda secara berkala.

Bila anda tidak punya koneksi Internet, anda bisa mendapatkan kumpulan update/patch dari Microsoft yang biasanya disebut sebagai Service Pack. Kalau anda menggunakan Windows XP, sangat disarankan anda menginstall Service Pack yang kedua (Windows XP SP-2). Di dalamnya banyak sekali fitur security yang ditambahkan. Di antaranya firewall dan popup blocker untuk Internet Explorer.

Firefox Eats IE
2. Disiplin Saat Browsing Internet

Kalau anda sering connect ke Internet, sebaiknya jangan gunakan IE (Internet Explorer) versi 6 dan sebelumnya. Gunakan Mozilla Firefox atau Opera. Kalau terpaksa pakai IE, pakai versi 7. IE 6 dan sebelumnya dikenal memiliki banyak lobang dan celah keamanan. Microsoft termasuk cukup lambat dalam mengupdate browsernya, karena itu celah keamanan sering dibiarkan terbuka terlalu lama tanpa ditambal. Selain itu seperti alasan yang dikemukakan sebelumnya, karena IE merupakan browser yang paling banyak dipergunakan, para hacker juga suka bereksperimen dengan IE.

Hindari pula berkunjung ke situs-situs underground yang menawarkan barang bajakan atau pornografi. Situs-situs semacam itu banyak menyertakan virus dan spyware secara terselubung bersama program-program yang mereka berikan.

Jangan sembarangan download apalagi install program dari sumber yang tidak jelas. Bila anda butuh suatu program dan anda menemukannya di Internet, namun pembuatnya tidak cukup terkenal atau bonafide, konsultasikan dulu dengan teman anda yang lebih mengerti apakah program tersebut cukup aman untuk dipergunakan. Termasuk jangan suka install toolbar untuk IE, screen saver, dan program-program tidak jelas lainnya kalau anda tidak paham konsekuensinya.

Firewall
3. Aktifkan Firewall di Jaringan

Kalau komputer anda terkoneksi di jaringan (LAN di kantor atau Internet), selalu hidupkan firewall. Windows XP SP-2 sudah menyertakan firewall yang biarpun fungsinya minimal tapi lebih baik daripada tidak sama sekali. Firewall akan menghalangi akses-akses yang tidak terotorasi oleh pihak lain. Firewall biasanya cukup ampuh untuk menangkal worm dan trojan.

Thunderbird
4. Hati-Hati Membuka Email

Email yang kita terima bukan hanya email yang kita harapkan, tapi bisa juga berupa spam atau junk mail. Biasanya email tersebut berisi iklan penawaran produk tertentu atau link ke situs-situs tertentu. Tapi tidak jarang pula email tersebut disertai satu attachment yang berisi satu aplikasi yang bila anda jalankan akan menjangkiti komputer anda dengan virus.

Pastikan attachment yang anda buka memang anda harapkan. Artinya anda memang menunggu kiriman sesuatu dari orang yang sudah anda kenal. Sekalipun pengirimnya sudah anda kenal, kalau ada attachment yang tidak anda minta, pastikan dulu ke pengirimnya apa isi attachment tersebut. Karena tidak jarang orang melakukan spoofing, menggunakan nama teman anda untuk mengirimkan virus.

Flashdisk
5. Hati-Hati Saat Membuka Storage Orang Lain

Saat anda membuka storage orang lain, entah yang removable (CD, DVD, Flashdisk, Disket, dan lain sebagainya) atau yang fixed (network share atau website), berhati-hatilah. Bukan tidak mungkin anda menemukan harta karun berupa file yang sudah terjangkiti virus. Sebisa mungkin jangan berbagi storage. Berbagi storage = joinan kuman.

AVG Antivirus
6. Pasang AntiVirus dan Anti Spyware Bila Perlu

Sebenarnya jika anda sudah mengikuti lima tip di atas, anda tidak memerlukan lagi software antivirus atau anti spyware. Tapi bila anda terpaksa (karena pekerjaan atau hobi) harus membuka situs-situs underground, terima email-email gak jelas, atau sharing storage dengan orang lain, sebaiknya anda beri proteksi tambahan pada komputer anda berupa program antivirus atau anti spyware.

Program-program ini biasanya memang bikin komputer jalan lebih lambat karena sifatnya yang TSR (Terminate & Stay Resident). Artinya begitu program ini dijalankan, dia akan tinggal terus di komputer anda untuk memonitor aktivitas anda. Setiap anda membuka, mengubah, atau meng-copy file, antivirus akan melakukan checking apakah aktivitas itu legal (memang anda yang melakukan atau virus yang melakukan). Program juga biasanya akan mengecek database internal nya untuk melihat adakah gejala-gejala komputer terinfeksi virus.

Kalau tidak mau komputer jadi lambat karena antivirus, coba gunakan antivirus AVG. Antivirus ini lebih enteng (tidak memakan terlalu banyak sumber daya komputer) dibanding anti virus lain yang lebih populer macam Norton Anti Virus, McAfee, Kaspersky, dan Bit Defender. Dan ada versi gratisnya loh. Jangan lupa, gunakan satu saja program antivirus di komputer anda. Lebih dari satu biasanya lebih merepotkan dan banyak konflik.

Untuk anti spyware anda bisa gunakan LavaSoft Ad-Aware dan Spybot Search & Destroy. Gunakan keduanya kalau perlu. Aplikasi anti spyware biasanya hanya dijalankan on-demand (saat diperlukan), bukan model TSR seperti antivirus. Jalankan anti spyware anda secara berkala untuk menghilangkan “mata-mata” dari komputer anda.

Bagaimana Kalau Sudah Terinfeksi

Keenam tips di atas adalah pencegahan. Bila diikuti, mestinya anda sudah bisa menggunakan komputer anda dengan aman dan nyaman tanpa takut dihinggapi virus-virus pengganggu. Tapi kalau anda belum melakukan pencegahan tapi komputer anda sudah kebobolan bagaimana penyembuhannya? Kalau sudah kebobolan, biasanya anda sudah tidak bisa menginstall antivirus untuk menyembuhkannya karena virus sudah cukup cerdik untuk menghalangi anda menginstall software antivirus.

Computer Technician
7. Minta Tolong Orang Lain

Langkah ini paling gampang, namun butuh biaya tambahan-bila anda minta bantuan profesional seperti teknisi komputer. Tapi juga agak beresiko. Bukan tidak mungkin foto-foto atau dokumen pribadi anda disebarkan di Internet oleh pihak yang tidak bertanggungjawab. Jadi kalau anda tidak punya teman yang bisa dipercaya, lebih baik anda belajar sendiri “menyembuhkan” komputer anda. Simak langkah-langkah berikut untuk melakukannya.

Eraser
8. Pembersihan Manual

Kalau anda tahu jenis virus yang menjangkiti komputer anda, anda bisa mencari informasi lebih lanjut tentang virus itu dengan bantuan Google. Situs-situs penyedia software anti virus biasanya juga menyediakan program-program kecil untuk membersihkan virus tertentu yang populer. Anda bisa mendownload program tersebut (biasanya gratis) dan membersihkan virus di komputer anda.

Sayangnya, biasanya virus tidak bekerja sendiri, begitu menginfeksi, dia juga membuka pintu (Trojan) untuk virus-virus yang lain agar masuk. Jadi anda bisa repot atau menghabiskan banyak waktu untuk membersihkan semua virus. Supaya praktis, anda bisa baca tips ke-sembilan.

Broom
9. Format dan Install Ulang Windows

Cara ini cukup efektif. Dengan format, anda menghapus semua isi harddisk anda, termasuk virus. Setelah format, anda harus menginstalasikan kembali semua program yang akan anda pergunakan, termasuk sistem operasi satu per satu.

Tapi hati-hatilah kalau harddisk anda dipartisi. Kalau yang anda format adalah drive C, sedangkan virus juga berdiam di drive D, setelah anda install Windows, saat anda akses drive D, Windows anda akan terjangkiti lagi. Formatlah semua drive yang ada untuk memastikan komputer anda bersih dari virus. Tentunya selamatkan dulu data anda sebelum melakukannya. Copykan ke flashdisk atau media lain.

Setelah anda install ulang komputer anda, segera pasang anti virus, lalu lakukan scanning ke flashdisk tempat anda menyimpan data tadi. Setelah bersih dari virus, baru copykan lagi data tadi ke komputer anda.

Sebagai tambahan catatan, melakukan. Beberapa orang mengatakan bahwa format bisa mengurangi umur harddisk atau komputer anda. Itu hanya mitos. Anda bisa memformat harddisk anda ribuan kali, harddisk anda tidak akan lebih cepat rusak dibandingkan menulis file ribuan kali juga.

10. Gunakan Sistem Operasi Alternatif

Bila anda tidak terikat dengan Windows-entah karena pekerjaan atau memang tidak bisa lepas dari Windows-anda bisa mencoba menggunakan sistem operasi lain. Kalau kegiatan anda dengan komputer hanya sebatas browsing Internet, email, membuat dokumen-dokumen Office dan presentasi, bekerja dengan spreadsheet, dan pekerjaan-pekerjaan umum lainnya, sebenarnya anda tidak perlu terikat dengan Microsoft Windows.

HOW TO RECOVER YOUR DATA

"Technology... is a queer thing. It brings you great gifts with one hand, and it stabs you in the back with the other. " ~C.P. Snow

It's an accepted fact that hard drives are the weakest link in computer technology. The hard disk is where the operating system and all software applications are stored. Because of this, a properly working drive is essential in the operation of any computer.

But since these drives are basically just an electro-mechanical devices, and like any other machine they will eventually breakdown and fail.



Cara Mengamankan data di komputer anda


Komputer adalah benda yang tak ternilai harganya, apalagi bila didalamnya tersimpan data-data pribadi yang sangat penting. Sebuah komputer ibarat sebuah ‘rumah’ dimana anda menyimpan semua hal, mulai dari file-file penting, foto-foto keluarga anda, film, lagu-lagu, sampai kepada username dan password untuk kegiatan online perbankan anda.

Anda tentu tidak mau kan, bila suatu hari nanti ada orang yang menyalahgunakan komputer anda dan mencuri semua data penting didalamnya? Oleh karena itu upaya pengamanan data komputer anda menjadi sangat penting dilakukan. Secara garis besar ada 3 macam gangguan yang paling sering mengancam keamanan data di komputer Anda. Bagaimana langkah pengamanan dari 3 ‘pengacau’ tersebut, berikut adalah langkah sederhananya.

1. User Error
Inilah sang pengacau pertama yang paling sering anda temui. Salah satu bentuk user eror ini adalah penghapusan file secara tak sengaja. Apalagi bila Komputer anda dipakai oleh orang “awam” maka kejadian menghapus file secara tak sengaja pun akan kerap kali terjadi. Masih untung kalau file yang terhapus adalah file yang tidak terlalu penting, tapi bagaimana bila yang terhapus tersebut adalah file yang sangat penting buat anda?

Upaya pencegahan atau pengamanan dari User Error ini sangat sederhana yaitu dengan cara melakukan back up secara reguler. Karena banyaknya data dalam komputer anda, maka sebaiknya anda membagi data anda dalam 2 kategori berikut ini sebelum melakukan back up

a. File yang sangat penting
Yang termasuk kategori ini misalnya daftar password dan username anda, atau file pekerjaan (presentasi, laporan bulanan, skripsi, makalah dll) yang sedang anda garap saat ini. File-file seperti ini ukuran tidak akan terlalu besar. maka lakukan back up sesering mungkin. Anda bisa mempergunakan Flashdisk atau disket untuk menyimpan file-file penting tersebut.

b. File-file umum
Data seperti lagu, program atau film-film koleksi sebaiknya anda back up dengan mempergunakan Blu-Ray, DVD atau CD sehingga bila suatu saat hardisk anda rusak, maka data andapun akan aman. Langkah lain, bila ada terhubung pada sebuah ‘network’ tidak adalahnya anda menyimpan file-file ini di hardisk komputer lain.

2. Virus

Sebuah virus bisa menyebabkan data penting anda menjadi tak bisa dibuka (corrupt) atau bahkan hilang sama sekali. Selain itu virus pun bisa menduplicate file-file di komputer anda, sehingga akhirnya hardisk anda pun penuh dengan file-file kembar. Upaya pengamanan terhadap virus ini bisa anda lakukan dengan cara mempergunakan anti virus di komputer anda dan usahakan agar anti virus anda selalu up to date dengan cara melakukan update secara berkala.

Atau anda bisa melakukan langkah sederhana dengan cara me-rename file penting anda dengan ekstensi yang lain. Misal anda punya file data.doc maka rename-lah menjadi data.abc. Virus ‘hanya’ bekerja dengan melihat ekstensi sebuah file (Misal file *.doc atau *.exe) jadi anda bisa sedikit mengelabuinya dengan merubah ekstensi file yang anda miliki tersebut, sehingga viruspun tidak akan menyerang file anda, karena ekstensinya tidak dikenali.

3. Spyware, Malware, Keyloggers/Hacking/ Phishing

Bagi anda yang sering online, maka ancaman-ancaman seperti ini akan selalu anda temui dan bisa mengancam keamanan data-data dalam komputer anda.

Spyware adalah aplikasi mata-mata yang akan memonitor kegiatan di komputer anda. Spyware ini biasanya akan merekam website yang anda kunjungi, mencatat password dan username anda dan kemudian mengirimkan kepada orang yang membuat program spyware tersebut.

Malware merupakan program yang bisa membahayakan komputer anda dan melakukan operasi tanpa anda sadari atau tanpa anda intervensi.

Keylogger, sebuah aplikasi kecil yang akan mencatat setiap tombol keyboard yang tekan. Aplikasi ini terutama ditujukan untuk mencuri data username dan password anda.

Upaya pengamanan terhadap pengacau seperti Spyware, malware, hacking atau keylohger ini bisa anda lakukan dengan cara :

- Pergunakan firewall di komputer anda, yang akan mengontrol aplikasi-aplikasi yang terhubung ke network atau internet. Jadi bila ada aplikasi yang berusaha mengirimkan data-data pribadi anda ke luar atau kepada orang lain, maka firewall akan memberikan peringatan kepada anda, sehingga anda pun bisa terhindar dari pencurian data ini.

- Selalu berhati-hati dalam menginstal atau mendownload file di internet. Pengacau-pengacau seperti ini bisa bersembunyi di aplikasi-aplikasi yang menggoda anda. Bila anda tidak terlalu mengetahui secara detil tentang suatu aplikasi atau program, sebaiknya anda jangan mendownload. atau mengintalnya. Selalu cek dan recek, perusahaan yang mengeluarkan aplikasi tersebut, kalaupun akhirnya anda tidak bisa menahan diri untuk menginstal aplikasi tersebut, sebaiknya anda download aplikasi tersebut di website yang benar-benar aman dan sudah terbukti baik kredibilitasnya.

- Hati-hati juga terhadap browser plug ini, active x atau java aplication. Bila suatu hari anda mengunjungi sebuah website, dan website tersebut meminta anda untuk menginstal suatu program atau aplikasi, sebaiknya anda hati-hati.

Pishing, sebuah website gadungan atau tiruan yang akan mencuri data username dan password anda. Terutama kegiatan phising ini ditujukan untuk online banking. Anda login pada sebuah website bank untuk melakukan transaksi keuangan, tapi tanpa anda sadari ternyata website tersebut merupakan website tiruan atau gadungan yang didesaian semirip mungkin dengan website aslinya. Akibatnya bisa anda tebak, username dan password anda untuk login ke website yang asli, telah berhasil dicuri. Dan tinggal menunggu waktu, bila kemudian data pribadi anda tersebut disalahgunakan.

Kegiatan phising bisa juga terjadi lewat email yang anda terima. Kebanyakan email tersebut mengaku dari bank atau sebuah instansi, yang menyuruh anda untuk login dengan mengklik link yang diberikan pada email tersebut. Saat anda mengklik link pada email tersebut anda pun dibawa pada website gadungan.

Untuk mencegah anda terkena pishing selalu pergunakan ‘secure email service” misal gmail, selalu mengecek kebenaran email yang anda terima dengan cara mengunjungi website aslinya, jangan sekali-kali mengklik link untuk melakukan login, usahakan untuk selalu mengetikkan sendiri alamat website yang anda tuju dengan ejaan yang benar, kalau anda login pada sebuah online banking pastikan website tersebut mempergunakan “secure login” (cirinya : alamat website tersebut berawal https:// bukan http://) dan juga mempergunakan physical security token yang akan lebih menjamin keamanan login anda.
