BleepingComputer.com: can't change homepage no matter what methods i try

you guys are my last resort, i can't seem to change my home page no matter what method i employ, it's only stuck in firefox, in IE and chrome my home page is fine. i'm sure it's malware/spyware, since after my sister installed some foreign games on my computer this problem has been occurring, but i don't know why it only is stuck in firefox (could it be it's my default browser). also, if/when you guys locate and isolate the problem found, is it also possible to notify me of any extra entries i don't need, since my computer is noticeably slower than usual after my sister installed her junk.

thank you

note: i don't want to not let my sister be able to play her games and stuff, but i know that spyware usually latches on to its programs, so if it's possible would she still be able to use her software so it's the best of both situations for us? she's 14 and doesn't know much about computing and the likes
