Both of the programs I mentioned above, SpywareBlaster and Spybot Search and Destroy, are anti-spyware related and dedicated programs and play nice with all anti-virus programs that I know of, including Kapersky, They should not pose any conflict or problem to Kapersky since they go after different things and don't/shouldn't get in each others' way, I believe. By the way, how do you like Kapersky? Me, I'm a McAfee user for about 8 years now and have no complaints and it has not presented any conflicts with the varied programs that I run, so I've stayed with it. Best to you
