Help! My PC is infected with malware (FAQ) InSecurity Complex - CNET News

What are the warning signs of an infection? An infection may cause the computer to run more slowly than normal, stop responding, or just crash. Applications may not work properly, and disk drives may be inaccessible. There may be unusual error messages and distorted menus and dialog boxes.

If spyware or adware is on your machine, in addition to it running slower, there may be new toolbars and links in your browser; your home page, mouse pointer, or search engine may be changed; you may be redirected to a different Web page from the one you typed in; and there may be pop-up ads even if you are not connected to the Internet.

How do I check for an infection?
There are a many free online antivirus scanners that can scan your computer for viruses and other malware, including Trend Micro's HouseCall, and Malwarebytes. (For the Mac there's the free ClamXav virus scanner.) Every major antivirus vendor offers scanners. Trend Micro's Perry suggests getting a second opinion if the scan fails to detect an infection and running a second scanner from a different vendor. Chances are that if one scanner misses an infection the other one will catch it since they use different technologies.
