So I got hit by a virus(posting from wii fyi) and it restarted my computer making a weird noise for a few seconds. So everything starts up normal until I get to the login screen. I log in and my computer immediately restarts. I tried Safe mode with networking and it did the same effect. So I did Safe mode itself and same effect but when I log into another account, it works. So I ran mbam and found 1 infection then removed it, it didn't work. I went to windows defender to look at startup programs, I noticed there was explorer.exe listed as something i forgot but it was a registry key. So i deleted it and it didn't help. I tried System Restore with no effect, but a few restarts later, I couldn't log in. BTW, I checked my task manager for any unusual processess but none but noticed in the performance tab, my cpu usage jumps to 100% frequently like a pattern with a red line, not your usual green line. Also in safe mod w/o networking I tried to open Chrome but it said it stopped working but firefox and IE opens but obviously no internet. Windows Vista SP2 64-bit
