There is a virus (more than one?!) calling itself NAPSTAT.EXE In Task Manager, I can see it using up tons of memory. The little blue circle is always spinning even when I am not running any programs. Both Microsoft Security Essentials AND MalwareBytes freeze upon running. Malware won't even get through its own update. This is very similar to the problem I had a few months ago--same evidence, different virus name. I run Windows 7 on a Dell desktop. Please, please help! I will give money for beer!
