|it started yesterday when my computer all of a sudden froze for a second then restarted. i was able to log back on that time but when i tried to open AIM it wouldn't log on. then i tried opening firefox and whenever i tried to go on a website it said something like unable to securely connect and a message would pop-up that said something about xml.freecause.com:443.|
i turned my computer off and this morning i tried to log on to my account and it keeps saying that i have the wrong password, even though i'm 100% positive i typed it in correctly everytime. now i can only go in the guest account because that doesn't have a password. i haven't tried to connect to the internet again with it because i am afraid someone has hacked into my computer or something. I'm currently on my brother's laptop.
Is this a virus? If so, what do i do? I installed the new version of firefox earlier yesterday. does it have anything to do with that? please help, i don't want to lose all my files.
