I tried AVG, but it was the scanning was ridiculously slow. In regards to McAfee, my laptop has a trial version of McAfee installed on it by default (which comes back everytime I reformat my computer) and my trial for it already ran out, so McAfee isn't an option for me.
I tried using what the top answer suggested in this link:

So far, I've got rid of this annoying pop-up that kept saying "You're infected with the Zlob.Xa trojan" or whatever. It's also got rid of this annoying banner thing that said "You're explorer is infected, find out how to fix this" or something along those lines which was always under the first link of my Google searches. Also, whatever my first Google search result link was, it would always redirect me to something related to some IE Defender program (yeah, I'm gonna totally trust your program if thats the link it suggests you to go to in order to fix my virus/trojan problem

). I'm not exactly experiencing the slowdowns from previous before trying that fix. Anyone know a good online virus scanner thing?
I think I was infected with the trojan Zlob.Xa or something along those lines. Here's some info on this IE Defender rogue anti-spyware thing:
