Well I was trying to install Sophos and it **bleep** well caused my system to go crazy along with sequential freezes and crashes of multiple apps, Firefox included as I had to start over and type this message again.
I can't say I'm pleased with this 'program' and for the time being I had to force-quit it through Activity Monitor that I had opened before starting the installation to make sure nothing went wrong... well it did. I mean what the hell just happened?! Although, as of force-quitting Sophos AV everything has seemingly went well on my system and apparently not caused any more issues so far, though if I restart it, the problems begin again.
