I just wanted to uninstall a program and noticed that's there are tons of new Adobe applications I've never seen before as well as some other applications I don't know. Only a handful of programs have the uninstall button, but most of the applications can't be uninstalled because the button is simply missing. Here's a screenshot:

Spybot - Search & Destroy and Avira Antivir didn't find anything. I'm logged in as administrator.
Any ideas?
