Ok I finished the quick scan that was running while I wrote my post and it came back with a message that it can't check all files. These were the ones it can't check: http://imgur.com/3WXX6yK
avast just did a cleanup in signature folder .... so thats why you get the files not found error this error is usually gone if you reboot and scan again
Also, any recommendations on what I should replace Spybot with?
Malwarebytes ..... that you already have. :)
