This is what Spybot Search & Destroy reports when found:
Description:
SpywareDetector seems to be in close relation to Smitfraud-C. It is installed together with Smitfraud-C. and pretends to be an anti virus solution. Scanning with SpywareDetector will return viruses found (that were installed before by SpywareDetector) but the user cannot remove them without buying the full version for about EUR 20. As SpywareDetector is often installed with Smitfraud-C. against the user's will, full alertness is essential.*
I just now had to clean three entries from my computer that was definitely malware and placed there by SpywareDetector.
When a program is inside of another program and then inserts itself to your system (system files and registry) and is placed there to deliver information to its owner about you and your buying/surfing activities, that is not ONLY malware, that is a TROJAN!
Here's another Spybot S&D report regarding MaxSecure RegistryCleaner.
McAfee declared their website as unsafe:
