trojan injector.EL

I've had this trojan on my computer for a while now, haven't been able to take the time to remove it...it's been quite a few months.

AVG recognizes it but can't really remove it (says it's been moved to virus vault but it keeps appearing) - it opens everytime a browser is opened (FF or IE), and occasionally a warning will just randomly pop up. Very rarely, random commercials will start playing, even if no programs are open at all. I'm fairly certain that the virus is why I can't run very many programs at once without everything slowing to a crawl, but that's just a guess (I have a ton more storage space, so I don't think that's a problem at all).

This particular trojan blocks a lot of the malware removal programs as well (I had to rename SAS and MB to even run them, but partway through scans they just stopped).

As you can see, I only have 2 of the 5 logs, the MB and SAS scans froze whenever I tried running them, and the ComboFix...I couldn't shut down my spyware programs all the way (I'm probably just missing something obvious) so I didn't want it to run and potentially mess up my computer even more. The last two, Root Repeal and MGTools worked just fine.

I've probably forgotten to include some very important information, I'm not very tech-y at all...

Thank you for your help, I'm getting very frustrated with this!

 

Thanks! Here's the logs for MB and SAS. I've stopped getting warnings from AVG when I open Firefox, so it seems like there's progress!
