This all started when my mouse started acting weird (right-click menus opening without click, slow responses, snapping to corners), so I started a massive malware and virus scan with MS security essentials and spybot search and destroy. I noticed my windows defender was turned off and tried to turn it back on to no aveil. I also updated security essentials. I set for full scans and went to sleep. In the morning I saw the computer restarted. I logged in to find a message saying I may have been a victim of software counterfeiting from MS security essentials. All my microsoft software were opening windows saying that it could not validate my OS. I needed my product ID. I went to look for it and under product ID it says, "not available". I started trying to repair, restore my Windows 7 professional 64 bit edition without any luck. I didn't make a disk image. I do have my files backed up on a separate drive. Now when I start the computer, after I sign in to windows, I immediately get a blue screen with a registry error and the following codes: 0x00000051, 00000000`00000001, fffff8a0`000242e0, 00000000`00e9d000, 00000000`00000374
Blue Screen View says it was caused by ntoskrnl.exe.
Any1 able to help?
