Kebanyakan virus menyamar seperti folder,word doc, atau icon2 yang boleh mengelirukan user, kadang kala ia disembunyikan bersama autorun.inf.
Oleh itu, jangan sesekali double-click sebarang file atau folder yang mencurigakan.
Kebiasaan virus berada dalam bentuk applications (.exe). Ianya seperti recycler.exe, ravmon.exe, psp.exe ..etc
Right-click dan lihat properties folder atau icon tersebut dan lihat type samada folder atau applications.

Computer Virus
A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the owner. The term "virus" is also commonly but erroneously used to refer to other types of malware, adware, and spyware programs that do not have the reproductive ability. A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.
The term "computer virus" is sometimes used as a catch-all phrase to include all types of malware. Malware includes computer viruses, worms, trojan horses, most rootkits, spyware, dishonest adware, crimeware, and other malicious and unwanted software), including true viruses. Viruses are sometimes confused with computer worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a program that appears harmless but has a hidden agenda. Worms and Trojans, like viruses, may cause harm to either a computer system's hosted data, functional performance, or networking throughput, when they are executed. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious.
Most personal computers are now connected to the Internet and to local area networks, facilitating the spread of malicious code. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, Instant Messaging, and file sharing systems to spread.

Whats New On Microsoft Windows 7?
Windows 7 was built around your feedback, so you'll see a lot of things you've asked for. You asked us to make everyday tasks faster and easier, to make your PC work the way you want it to, and to make it possible to do new things. And that's exactly what we're doing. See how it's coming to life.
Improved taskbar and full-screen previews
The taskbar at the bottom of your screen is what you use to launch programs and switch between them when they're open. In Windows 7 you can pin any program to the taskbar so it’s always just a click away, and you can rearrange the icons on the taskbar just by clicking and dragging. We’ve made the icons considerably bigger, too, so they’re easier to use. Hover over the icons and you’ll see thumbnails of every file or window that open in that program, and if you hover over the thumbnail, you’ll see a full-screen preview of that window. Move the cursor off the thumbnail and the full-screen preview disappears.
