Aimersoft

There is a company called Aimersoft which apparently has the same software for sale under different names. Total Media Converter and Aimersoft Video Converter are two examples which obviously have the same interface. People have examined the package installers and found the two to be essentially identical, right down to the same Read Me file.

Someone's delved into it a bit deeper and it seems like this company (which goes by a list of different names) has a group of people posting blog posts, comments and reviews (even on bogus review sites they create) to promote their software.

There's info about this mess here.
