This just started happening: Running Firefox 10 (started in 9 before updating), doing a search in Google (either from the Google.com website or the search engine box in the upper right corner of Firefox). With me so far? I do a search (used Bleepingcomputer). The Google search results look fine, but the search link is messed up. Bleeping computer should be "http://www.bleepingcomputer.com".
Instead it is "http://www.bleepingcomputer.com/&sa=U&ei=IMI6T7ruFeXs2QXv5oCyCg&ved=0CBEQFjAA&usg=AFQjCNFnCpAywSTLxpxpGDkZuCprOY5nxg".
This is on every search result. The characters are different, but the result is the same when you click on it... a lot of 404's, can't find file, url, etc.
Tried wife's PC and my notebook, search is normal.
Running new HP i5 Quadcore, 8GB RAM, 1TB drive, 2GB Video card, 64 bit, Windows 7. Plenty of space, cache, cookies, temp files, etc. is cleared (using ccleaner from Piriform). Have run Malwarebytes, Avast, TDSSkiller. System appears to be clean. Hosts file has not been altered. Nothing ordinary that just jumps out and slaps you in a hijackthis report.
I'm hesitant to remove and reinstall Firefox because of all the plugins I've got. Besides, the same thing happens in IE. This seemed to start happening after upgrading a Silverlight request. (Which I've removed, but hasn't made a difference.)
Ideas? Questions? FIXES?
