Apparently, the new Symantec product called Symantec Endpoint Protection may cause Blue screen errors in both Windows XP and Vista. Our Windows department at work recently begin upgrading individual workstations to this new version and Blue screen errors began almost immediately. Here is an example of the error message some of our PCs are getting:
Faulting application Smc.exe, version 11.x.x.x time stamp XXXXXX, faulting module ntdll.dll, version 6.0.6000.16386, timestamp XXXXXXX, exception code 0xc0000005, fault offset 0x00061635, process id 0x694, application start time XXXXXXXXX
Basically, the solution is to turn off some of the protection included in the software package....if you ask me, what's the point? If its going to cause errors, why even release the software.
Just another case of a vendor not testing software 100% before releasing it. Don't get me wrong, I am a big fan of PC security, but if a product does not do what it should, don't release it until fully tested.
