Kaspersky and Spybot S&D conflicting?

My roommate doesn't have the, er, malware savvy that I do, so he's asked me to clean up his computer. I'm doing all of the scans, and Kaspersky keeps finding Spybot's backups and calling them out as malicious. I'm letting Kaspersky delete / disinfect them as it sees fit, but I was wondering if anyone else had run into this problem?

Just a bit annoying, I guess :unsure:.

Probably just a false positive.... I'm only running AVG Anti Spyware and Windows Defender now... along with Norton Internet Security.

I had used Spybot...but I'm taking the guess it's just a false positive.
