I installed remotly through admin kit, kav wk 6.0228 on ten pc ,where previously was installed kav wk 4.5 . on some pc anti-hacker module failed to start.
All Pc are win xp sp2 whit the same configuration .

Any suggestion ?

Maybe the 2nd Windows Firewall Service is running on that machines - look under services for "Windows Firewall/Internet connection Sharing" and disable this service.
Otherwise take a look into the eventlogs to figure out where the problem comes from.
