I've tried several virus / spy-ware programs to detect the problem (MSE and Defender scans, HijackThis, Ad-Aware, and Spybot), as well as some other tools (TDSSKiller, CWShredder, and resetting the HOST file via the Microsoft web download). None of them have done anything. Neither does re-installing Firefox.
Does anyone have any ideas about what this may be? I haven't actually seen it re-direct me to any strange pages besides the initial homepage and the embedded Google search, so I'm not sure it's a typical browser re-direct virus. Just that not only is this annoying (changes homepage / unselects function to re-open prior tabs), but I'm kind of worried to be logging into any really private sites like banking.
