Pc tune up, maintenance

George, we would suggest you to clean those keys. Though the scan finds such keys repeatedly, they are not the same as the previous one. Thank you.

I looked up the area that maintenance showed what can be cleaned up under browser and found this file
{B2B04F8B-6444-4364-89C8-F3088D4E8D02}, I googled it and it says it is a viruses.  Once I tried buying PC Pro, which it turned out to be a bad idea.  I had my computer reformated and windows 8. reinstalled at a computer shop, they installed the best anti viruses program which is AVG.  But everytime I run maintaince, it comes up with diffrent numbers to be cleaned up, and I can run, rerun and rerun and never get a clean pass.  Is there something wrong?  Is there anyway to insure I do have a clean computer?
