Using the latest beta. I noticed this morning that Prevx real time was turned off. Went to turn it on and had a BSOD. This was quick so didn't have a chance to catch the numbers. After the reboot the keyboard would not respond. Mouse was ok. tryed a different kb this didn't help. Scanned with Avira boot cd and this came up clean. Can't get to system even in safe mode because it can't get pass the pw screen. Running Win7 HP (7600). Right now I'm restoring a image from last night. I don't suppose Prevx removed the keyboard driver?? The other av I was using was NIS2010.
