I have somehow acquired an odd virus. When I start up my computer a Security Center Alert comes up asking if I want to block suspicious software called Win32.Zafi.B with a high threat level . There is an enable protection button. I've pressed the button and when I do mozilla firefox comes up with a window that says restore previous session and start new session. When I restore previous session it crashes. If I start new session my homepage does not go to google but rather to a warning about their being a threat and suggesting me to continue without protection or buy windows defender. Sometimes I can continue but if i search in google or go to a website it often crashes right away. I cannot run STEAM either it just crashes after I log on. Explorer also seems to have problems as well. I have no clue what to do.
So I ran Super Anti-Spyware, Malwarebytes, and Norton Malware. They found problems but not of them removed this problem. I also cannot post a HIJACKTHIS log because I can't really get on the web with my other computer. I guess I could transfer it to this comp with a keydrive but I don't know if that'll transfer the virus somehow.
