Endpoint Protection

I have a client machine with win xp sp3.
earlier it was working fine with sep 11 mr4 mp2 installed on it. but for some reason user uniinstalled sep and later when i installed sep on that machine it boots fine but when sep starts a BSOD appears(memory dump error) . again i removed sep (through add/remove program and cleanwipe) and installed sep (managed) the same thing happened.

one thing i have noticed eachtime i install sep after removing it a new teefer2 driver gets installed like teefer2 #1, teefer2#2 and goes on.

is this the cause of the problem. hwo can i see the teffer2 driver in lan properties in mr4

 You will have to check in the memory dump what is the cause of the issue..

Teefer2#1,2 ,3,4,5 will go on till you keep re-installing it its like your LAN card once you re-istall it becomes LAN2,3,4,5..

what is the message seen in blue screen, you may use those keywords to check in Microsoft site!!
