Hi Mike,

> I use zonelabs security suite. I wonder how to fix this?

Well personally I would just ditch any anti-virus software that had such a continuous negative system performance effect.

But often times software like that will have some settings in it that will stop it from interfering with certain specific programs, so you can kind of turn it off in a more fine tuned way rather than just all on or all off. Look for some settings like that and add MoI.exe to any list of programs to not interfere with.
