I’m using Windows Vista SP1. I have AVG antivirus. Whenever I try to log in to Windows, the computer freezes after a few minutes. I think that SVCHOST.EXe is the problem. The memory usage increases and increases and when I saw the memory for svchost.exe it was up to 442300 or might be 4423000. It works fine in safe mode. I am very worried about this. Please help me to get rid of this problem.
