On the bottom right dock of Windows XP there is a little red shield with an X in it, the same as the XP Security logo that is there. A text box pops out that says “You have a security problem.” If you click on the box it takes you to a web site called pro-scan-online.com, saying it is doing a “Free Virus Scan”. It NEVER goes away. Everything on the website is very shady. Has anyone else experienced this problem?
