It all started when I noticed that when I pressed ctrl alt del nothing happened. Then later when i typed regedit in the run box it said regedit was not a valid win32 application. First i tried to run the trend housecall virus scan and it seemed to be working rather well, finding lots of Malware. Before I could delete the malware and before the search was finished a message would pop up, saying "The instruction of 0x10101012 referenced memory at 0xffffffff could not be read. Click ok to terminate the program. Click cancel to debug the program" I tried both (i tried the search many times) and regardless of what i did the window would always close. Next I tried spysweeper, which for some reason could not find my internet connection. Spyware eliminator worked and removed some spyware, but it still didn't solve the regedit problem. Then a ran Ewido which I think also helped but still regedit wont open and my taskmanager still has problems. Any help would be greatly appreciated.
