FreeSmartSoft is the developer of a range of popular Windows freeware, including FSS Video Downloader, FSS Google Books Downloader, FSS ePub Reader and more.

Youíve installed one of their packages before? Then beware: weíve discovered they have a mechanism that can silently install adware on a userís PC.

The issue is with a component called FSSUpdaterService, which is installed as a part of some FSS applications.

Sounds like just another innocent software update checker, right? But itís not as well behaved as some other applications. The installer doesnít ask if you want to allow the package to phone home, and we can see no option to turn it off.
