SafeSurf,
Thanks for the reply,I can't update to Vista Sp2 without a complete new install,and that's a major hassle pertaining to Vista but mainly Dell, their worthless Media Direct and Partitioning along with Dell's lack of any help or common courtesy(long,maddening story)!
I did update to 6.0.1125 and have not had the problem on restart,I will wait and see if this was a random occurrence as others have said?
One other question though, What unauthorized changes would be made by Avast to Windows to cause this error- (0XC0094D401)[The security processor reported a system file mismatch error]- this only started after the last Avast Program update?
Any help is greatly appreciated,
Thanks again,
Steven
