What are viruses and other malware
Malware are programs specifically designed to damage your computer, use your computer for illegal purposes
without your knowledge, or steal information from your computer.
Malware can:
• take control over your web browser,
• redirect your search attempts,
• show unwanted advertising,
• keep track on the web sites you visit,
• steal personal information such as your banking information,
• use your computer to send spam, and
• use your computer to attack other computers.
Malware can also cause your computer to become slow and unstable. You may suspect that you have some
malware on your computer if it suddenly becomes very slow and crashes often.
Viruses
Viruses are usually programs that can attach themselves to files and replicate themselves repeatedly; they
can alter and replace the contents of other files in a way that may damage your computer.
A virus is a program that is normally installed without your knowledge on your computer. Once there, the
virus tries to replicate itself. The virus:
• uses some of your computer's system resources,
• may alter or damage files on your computer,
• probably tries to use your computer to infect other computers,
• may allow your computer to be used for illegal purposes.
Spyware
Spyware are programs that collect your personal information.
Spyware may collect personal information including:
• Internet sites you have browsed,
• e-mail addresses from your computer,
• passwords, or
• credit card numbers.
Spyware almost always installs itself without your explicit permission. Spyware may get installed together
with a useful program or by tricking you into clicking an option in a misleading pop-up window .
Rootkits
Rootkits are programs that make other malware difficult to find.
Rootkits hide files and processes. In general, they do this to hide malicious activity on your computer. When
a rootkit is hiding
malware , you cannot easily discover that your computer has malware.
This product has a rootkit scanner that scans specifically for rootkits, so malware cannot easily hide itself.
Riskware
Riskware is not designed specifically to harm your computer, but it may harm your computer if it is misused.
