There's a new thing out called "Search Settings 1.2.1". Normally I don't blow the whistle on these sort of things, but I must stress that this is NOT a virus, malware, spyware, or anything malicious! If you look online 99% of the results say it's malware but it's not! If you go download some crap to get rid of Search Settings, you're just going to get a REAL virus.
Normally I wouldn't be concerned, but 14 of my computers have come down with this. It's a rogue package installer and it'll keep trying to install and install and it really acts like a nasty bug. All you have to do is download the package install cleaner from Microsoft and remove Search Settings from the list and it will go away. It seems that MS has released an update that doesn't work on most computers. Typical.

There should be a new update out in a few weeks, but until then if you get the Search Settings setup program going all of a sudden go download the package install cleaner from MS.
