Firefox crashed earlier and I tried starting it back up (checked to see if the process was running but it wasn't) and nothing happens. I try again nothing. I try starting it in safe mode, it starts up showing my previous session, I click restore and it crashes, I try again hitting start new and it crashes (even if I don't click anything). I tried opening the profile manager and that crashes. I tried to run a system restore, but it will not restore to earlier. I'm thinking it could be some malware, but have no idea where to begin on an issue like this.

Whenever I try to start it the process starts, but it crashes after a few seconds.
