I have OneCare. My computers have been hit twice this year by a spy ware called Vista Antivirus 2010. It takes over IE. It cost me $200 so far because OneCare does not protect against it. The People at Best Buy say OneCare is useless against this thing and is a waste. Now I have a computer that got hit again. Now either give me an answer or get ready for OneCare to be exposed as the waste that I find it is.
I'm not aware of any security software that protects 100% against the rogue "antimalware" pop-ups that are constantly morphing. As soon as the vendors code to protect against this malware, the writers modify the code to successfully bypass the security and trick *you* into allowing the PC to be infected. Your best bet when one of the popups appear is to ctrl-alt-del, start task manager, and kill all iexplore.exe instances. Then reboot the machine, and go to Control Panel/Internet Options and delete your temporary Internet files. Clicking on the popup in any way will allow the PC to be infected. As a OneCare subscriber you have access to *free* support. Although I shop at Best Buy, I find their advice to be rather useless. Jim already provided you the path to support.
