Teatimer is runtime protection. Don’t use it. It doesn’t really work anyway.
Spybot S&D scans the registry as part of it’s general scan and should catch most malware related problems. You can also use CCleaner for more general stuff.
Most registry programs are overly invasive and I wouldn’t use them if you paid me. If you have a specific problem in mind, google it for the exact answer, other than that you need to avoid playing in the registry as you can screw things up in a jack flash.
