Part 5: Virus protectionViruses, Trojans, and other malicious software programs pose a great risk to computers. Several forms of malware are spread by using e-mail messages. However, a computer may also become infected when you search the Internet. This problem may occur if a new security vulnerability emerges in your browser or if you download a program that you believe to be trustworthy, such as a computer game, that it is actually a backdoor program.
Viruses and Trojans can cause major damage. These programs can damage single files or delete a whole hard disk. They can use a computer to attack an Internet server or to send spam. They may also be able to "phish" for passwords and for other private information or cause major problems on a computer.
Virus protection programs are the only effective means of protection against these types of attack. These programs help prevent attacks on a system and remove any existing malware.
How antivirus software worksWhen you use e-mail programs or search the Internet, you subject a computer to viruses. A virus can infect a computer when you do something as harmless as clicking a file attachment in an e-mail message that is sent from someone on an infected computer. The more that you use a computer for communication, whether this communication uses the Internet, e-mail, or file sharing, the more susceptible a computer is to viruses and to virus-related problems.
Protect your computer and your contacts by using antivirus software. Antivirus software detects, fixes, and prevents viruses from spreading to and from a computer. Antivirus software searches for latent viruses on a computer. This includes viruses that may have spread to a system without your knowledge. The software can also install antivirus fixes on a computer. These fixes help protect a system from future infection and help prevent the system from unintentionally spreading viruses to other computers.
Unfortunately, some computer viruses are not discovered until you try to upgrade or to modify software. Therefore, we recommend that you use antivirus software before you install Microsoft Windows XP.

Microsoft Windows Malicious Software Removal ToolYou can help protect a computer from malicious software by using the Malicious Software Removal Tool. This tool checks Windows XP-based, Microsoft Windows 2000-based, and Microsoft Windows Server 2003-based computers for specific, prevalent malicious software and helps you remove threats after they have infected a computer. When the detection and removal process is completed, the tool displays a report that tells you which, if any, malicious software was detected and removed.
Each month Microsoft provides an updated version of this tool that removes malicious software that is found to be prevalent for that month.
