I just downloaded the free edition of Avast. This was found MBR: \\.\PHYSICALDRIVE0, Threat:Rootkit: hidden boot-sector So I let Avast delete it, then it wanted to reboot and run a scan. Upon reboot I got a blue screen and cannot get into any form of windows at all. I can access the recovery and that's it. What do I do? This is my laptop for work, I can't afford to loose all the info on it. Please help!!!
