cis causes 100%cpu system process

Hi I have a huge problem with cis 7.0 as it causes 100%cpu for System process on my newly reinstalled windows xp sp3 pentium 4 2.8.

Could you please make some suggestions how to possible resolve the problem. I assume this is CIS fault as any change in CIS + any new action on my computer causes 100% CPU for System proces.

I’m going to work now, will be back in about 2 days,

Cheers,
Slawek
