Bsdelfpr.sys Bsod With New Xp Product Installation Bitdefender 2010


After installing your NEW BitDefender 2010 product on my Windows XP system, it will not boot, giving me a BSOD, driver_irql_not_less_or_equal 0x000000D1 error. My system will reboot, generating a corrupt Minidump file with no info. My system will then 'recover from a serious error' and boot normally. The file bsdelfpr.sys IS NOT PRESENT in my system. I have Updated BitDefender 2010 to the latest version. I have registered with you, and Activated my copy of BitDefender 2010.

So far, I am Not Impressed with your product.
