As most new posters - I found this group because I have a problem. I'm hoping the colelction knowledge of this forum will help me get to the bottom of this one.

I have several systems on a small network that seem to be passing around a virus that Nortn can't find. The symptoms are the repeated display of a Data Execution Prevented message that simply says that a Generic Host Process has been prevented from running. This comes up repeatedly every time the systems are rebooted, but stops after about 8-10 times. After that they get another message that says a program has attempted to write to memory location 00000000. This shows up randomly the whole time they are runnign the systems. The only other symptom is a general slowing down of everything.

The only systems that seem to be affected are those running Win XP (SP2). There are a few W2K systems that appear to be OK.
I've actually wiped out one of affected systems down to repartitioning the HD, but the problem came back within three weeks. I think it's passing back and forth through the network.
All systems are running at least Norton Anti-Virus 2005, which does not see any problem. Has anyone seen anything like this lately?
Thanks,
