found out what a lola is lol.

For some reason
www.free-lola.com has set itself as a homepage and it can't be undone. I've deleted cookies, changed in under internet settings to a differnet page and I've tried cleaning out all the interent files that I could but it still comes back if you restart the computer. I did a search for any files that might relate to that site but could find anything suspicious.
Anybody know what I can do to get rid of it?
