Well, that's some shady shit. Obviously if it may be unwanted, then it isn't a false positive. And the direct download link nonsense is also suspect.
1. If at all possible, get any program you download directly from the maker of said program. Neuber STM has the install exe, and JUST the program install, right on their webpage. They even have a zip if you want to run it without installing, which is pretty rare. Not necessary to go to CNET. Third parties love to piggyback installations with their bullshit, and while CNET used to be an ok mirror for lots of files, it isn't anymore. They are deceptive.
2. If getting it from a third party is your only option, pay attention to the install options. Check in custom. There's almost always "a great new service" or "quick answers with our new search option!" in the program install that's really just more bullshit; that being said, there's almost always a box that lets you NOT install it.
It isn't just third parties anymore, quite a few free progs we all know and love are loaded with this stuff.
Gotta be cautious out there fellers.

This is weird. The anti-virus/malware programs removed this crap from FF. But did not remove it from IE. I didn't notice because I almost never use IE. But IE is currently unusable by me because it's locked in to that Blekko taskbar, and the programs that removed it from FF don't seem to remove it from IE.

From the BLekko website ...

Thanks.
