Need some help.

Well, I was on Facebook and I noticed that it shows that I 'Liked' a picture that was uploaded a few hours ago. Yet, I wasn't even on Facebook.

The 'Like' was on a "Jane Smith changed her profile picture," so, it could just be that I liked it before, but I simply don't remember the image.

Just to be safe, I'm running MalwareBytes and resetting all of my passwords and such in case of a RAT or key-logger. I just want to know what else I can run to keep my laptop clean.

My AVG hasn't picked up anything until I went to download Dark Comet's RAT remover.

Try those. They're free, good virus/malware scanners. This area really isn't my speciality though - you'd be better off checking other forums/sites to be honest.
