I have scanned with Norton, AVG free, SUPER Anti Spyware, and Walwarebytes' Anti-Malware, and each search has come up with nothing malicious found. I have also tried system restoring to a date before I starting having these problems, and it said the restore failed. I have uninstalled Fire Fox, downloaded it on another computer and transfered it to the ailing one via flashdrive, reinstalled it and everything to no avail.
I honestly have no idea what happened to it. It was working around two in the afternoon or so, then I went to work and came home around ten and it was not working.
Any advice and help will be greatly appreciated.
