I have never heard of anything like that (then again taking the right steps means you don't run into viruses at all). Run an antivirus (Clamwin or AVG are some free ones), scan for spy/adware (Windows defender, Lavasoft Ad-aware, etc.), and uninstall mysterious applications. If this doesn't work, find your local computer guru and get him/her to look at it.
