Answer
Hi Alan,

First thing, you should never run more than AV program at any given time as they will usually conflict with one another. No matter which program you use, keep it up to date and run a virus scan at least once a week.

To verify that the threat is on the computer, I would suggest using Internet Explorer and go to:

http://security.symantec.com/sscv6/default.asp?langid=ie&venid=sym

Click the GO button, then under Virus Detection, click Start. You might be told that you need to download and install ActiveX Controls for the scan to work, answer Yes.

Write down exactly anything it finds, then go to: http://www.symantec.com/search/  and do a search for what was found. Symantec usually has a removal tool and/or directions for removing manually. Make sure that you follow the instructions for removal, step by step, especially the part regarding disabling System Restore.

Hope this helps!
