I've got a quick question regarding Mcafee. I just updated one of my company's PC's dat files. The user is on 4.5.1 and I updated the dat files to the lastest dats from http://www.nai.com

Now when I boot the machine, I receive a blue screen and a STOP error.
Anyone know why, and/or how to solve this problem.

I have never had this problem before when updating a users dat files.

thanks
