Re: WHITCH is the best antivirus program for windows 7 whitch don't cause BSOD??? I'm using AVG Internet Security Suite for Win7 64bit... I do not have any bugs since I disabled the "accelerator". In my opinion, it's a waste of coding space and an issue for end users on a good product. Do know if that's what giving you the 'bug', but here's the instruction to disable the "accelerator". I highly recommend disabling the "accelerator". Go to AVG Tools -> Advanced Settings -> LinkScanner -> Online Shield -> uncheck "Enable AVG Accelerator".
