Dont get me wrong, Im not knocking the program. Id love to continue using it. This was a process of elimination. I did check for malware for first, even using Icesword in case of something sinister. Then I removed SP3, with no change. Then I tried removing Comodo fw, still no change. It didnt improve until I removed MBAM, Pro version. Here's a brief story. I had a similar problem a couple of weeks back, which I put down to my removing a partition and extending the Windows partition. So I formatted and reinstalled for a new start. Then it started again. Im assuming there is something unique happening with my pc and MBAM, as this begins after a few updates. FYI- pc is XP Pro, Athlon 3200, 1.5gb, 160gb HD. I have Avast, Winpatrol Pro and Comodo. I have very few programs installed. I dont know if it makes a difference but I did install the Far Eastern language packs. One last point, but again, I dont know if it makes a difference, before I uninstalled MBAM I got Task Manager open and saw mbamservice was using over 27000kb's of ram, one of the highest usages.
