It looks like the software that runs a hardlock dongle: a piece of hardware that is used to prevent software piracy on certain programs. If you don't have anything like or connected to your compuer, you probably don't need it.
Do you have Ad Aware (download.com)? It's just like Spybot S&D but sometimes it seems to catch different things so perhaps it could delete the files you're having trouble with when you use Spybot. If not, it's still handy to have.
