I also use Avast and have had far fewer problems with that, than any anti virus I have ever used. A deputy sherriff told me he used it and so did everyone in the department and they never had a problem.. None I have ever had came close to doing what Avast does.. That things updates all day long. I strongly urge you to dump what you have and get that.. I use limewire from time to time and it has caught every virus BEFORE it got to my machine. The best part of it is that it is completely FREE! (just my kind of price!)
