Hi, A few days ago I think I contracted a virus - I turned on the PC and the screen was covered in adware, pop-ups and the like. One of those being alluded to was W32.myzor.FK@yf. I was also bombarded with antivirus software adverts telling me that my system had been infected with a number of other viruses. Having done a quick search, I have followed a number of procedures on this site (those based in the sticky threads). I have scanned the PC using a number of tools, some of which have found a few things which have subsequently been removed but nothing that looked too major. It was a bit diturbing though that my own Anti-virus software (McAffee/Norton) picked up nothing.... However, I am left with two problems. First, is the machine occasionally makes random sounds for no apparent reason. Second, and more disturbing is that the systems keeps freezing. Its like it functions fine for about a minute, at which point everything just stops for about 2 minutes. This repeats over and over again. A look at the task manager does not show any unusual movement when things are frozen. Its so bad that it has taken me about 10 hours now over 2 nights to complete the few tests in the sticky threads. Please help. Attached are the logs that are required. Many thanks.
