I have been having chronic problems with slow downs and lock ups in Windows 7 and Office 2003 programs. I have found no good answers but have discovered if I uninstall Bitdefender (not just Repair), then restart the computer, my problems are gone. Then I can re-install. Things go along OK for a day or two and then, most often after allowing my computer to go to sleep for the night and reawakening in the am, my problems are back...and Bidefender is logging a host of supposed Trojan infections. Has any one else experienced a similar problem. Is there something profoundly wrong with the marriage of Bitdefender and Windows 7?
