Couple quick things: slows down my pc, constant pop ups, very slow scans. BUT:Worst issue is my recent bout with PC_Antispyware2010 (which, for those of you who haven't been infected, is NOT spyware, it IS the virus!!!). My home pc had no virus protection (my bad) and got hosed with the PC_Antispyware2010, which has a long list of trojans and virus' and spyware attached to it. Loaded this product and it did not detect, or remove the virus. Only after a web search did I find out McAfee cannot handle this particular virus. I purchased Norton and it cleaned my PC. I'm sure another prodcut would work too, but I knew of Norton. But McAfee was a huge and costly disappointment. Pass on this; there are many better options out there.
