I'm not getting that. It's working fine for me. When you say 'any trainer' you mean either W3 trainer or any trainer for any game? You're giving the trainer Admin rights?
I'm using the 1.06 trainer for the 1.06 patched W3. You might try running MSCONFIG when it happens to see if maybe some module of the AV is still running in the background and killing the trainer. A lot of the AV apps will lead you to believe you've disabled them only to find out something like real time scanning is still running in background.
I used to use McAfee a few years ago and it did that to me. Even though I thought I had it turned off and had made exceptions for the trainers, it was still killing them. When I called them about it and asked if there was a way to completely disable it, they said "nope." So I said bub-bye to McAfee after that.

Well, it started happening about 2 weeks ago. My AV has been good all this time. And yes, I always give the trainer admin rights. So I'm not quite sure what's going on.
I'm starting to think it's windows 8 because all my trainers for any game just crash/shutdown.
