Hi there.
Over the weekend I've managed to get hold of a virus/trojan that infects the lsass file, and I can't seem to get rid of it! The virus is kind of like a time bomb- it switches my computer off without warning at unpredictable times, and then whenever you try to boot the PC up, it gets as far as the windows loading screen before saying "warning: unable to open lsass.exe" and then closes itself off. It has some sort of time release on it, and you can't boot up your pc for a couple of hours afterwards. I'm not entirely sure how I picked it up, but I think it was from a download I extracted into a game.
No anti-virus software, including avast! is picking this up, nor is spyware or adware programs. I've tried doing a system repair, and the computer just shuts itself off with any type of repair work done to it. :/
Can anybody help me please?
