Using more than one anti-spyware program with a resident protection tool might cause conflicts. However, Spybot - Search & Destroy's Resident protection is designed such that there should not be any compatibility issues.

One thing that could appear is that another programm detects our TeaTimer as bad - because theoretically, it has the same function as a keylogger as it runs in the background. But only theoretically - it is a realtime protection tool for you and there is nothing bad about it.

Another issue could be that the Keylogger detection files Keyloggers.sbi and Keyloggers.*.nfo of Spybot-S&D are detected as Activity Monitor keylogger. These detected keyloggers are just the Spybot-S&D detection rules, which obviously need to contain the names of the threats. Please ignore these false positives.

For more information we created a compatibility overview (online link) listing some software for which there have been questions on compatibility.

One last thing could be that removed items which are now stored in the recovery area as zip files are being detected. The zip files are needed for the recovery. If something does not work after fixing a problem with Spybot-S&D you can restore these files. So there is nothing bad with them, either.
