While many people in the anti-spyware sector are doing this mostly because they are dedicated to security and privacy, there are always a few black sheep trying to make quick money using the fear of many users.

Two such black sheep are BulletProof Soft with their Spyware and Adware Remover and TrekBlue with their SpywareNuker.
Both products are based on a hacked version of the Spybot-S&D database. Evidence for this is very clear as Spybot-S&D contains some entries to determine such theft. These entries are wrong entries, some detecting things that do not really exist, some detecting minor threats under the wrong name, etc. These tricks are absolutely harmless to the normal user of Spybot-S&D, but do clearly identify a stolen version of the Spybot-S&D database. Both products mentioned above detect exactly the same 'mistakes' the Spybot-S&D database contains.

I am in contact with two attorneys to sue these two companies. I recommend that you use neither of the two programs mentioned above. Using them is a copyright infringement!!! (and in addition you won't get more than with Spybot-S&D, as they are based on older Spybot-S&D databases)

Another interesting thing: there is someone 'spamming' at download.com: Spybot-S&D and AdAware have received thousands of negative feedbacks with the same text (CNet is removing them constantly), but the BPS Remover has gotten more than 10.000 positive feedbacks from the same name and the same text.

A discussion about this has been started at our old support forums (link removed on August 25th, 2006 since the old forum is no longer available).
