    Windows Antimalware Service Executable slowing down Firefox


    I seem to have an issue with the afore mentioned task. Whenever I start Firefox the task goes crazy, using about 30% of my CPU for several minutes. This is significantly more than other browsers. I have a second PC that is configured exactly the same but does not have this issue.If I disable real-time virus processing in Windows the problem goes away. I have reset Firefox and it didn't stop the problem. It's a recent problem, only affecting Firefox in the immediate past. I have also seen other people complaining about it very recently albeit no solution.

    :)
