Recent day,many people get ram disk with idle physical memory. I am one of them. Since a few day before,NOD32 have got update error,simultaneously my all received e-mail were broken. Why? Cause of problem is NOD32 use fixed temp location,that is c:\windows\temp. If you have changed temp location to your ram drive and delete c:\windows\temp then NOD32 can't update himself therefore he break your mail. ESET,Don't use fixed temp location,use user specified temp directory!
