when testing Kaspersky AV, dont just un-install it as usual as you'd with other AV's (NAV too an exception),

, download the "KAV/KIS Remove" tool from kaspersky labs website

, or be ready with Windows Install Disk
IMO get KAV or KIS & use ZoneAlarm Free (as firewall).
as Kniwor said, KIS/KAV are highly configurable.
just a example
