OneCare hanging Thunderbird RRS feed

  • Question

  • I have OneCare installed on my HP laptop with 64-bit Vista Home Premium. I use Thunderbird as my email client and leave it running all the time. Several times per day, Thunderbird reports as Not Responding, the mouse becomes difficult to move around the screen and the CPU(s) run at 80-100%. Looking at task manager, MsMpEng.exe seems to be the culprit. If I kill that task, everything immediately returns to normal, and so I've learned to kill that task any time I see it running. Of course, I'm guessing that makes OneCare pretty much useless.

    Any idea what to check?.
