So, this morning I've been getting alerts from my Avast! Antivirus about my PC being infected with a trojan. Since I also have MalwareBytes, I decided to run a MalwareBytes scan first.

The log from that scan:

Malwarebytes Anti-Malware

Database version: v2012.07.09.01

Windows 7 Service Pack 1 x64 NTFS
Internet Explorer 9.0.8112.16421

Though it says no action taken there in the log, I proceeded to quarantine and delete the file afterward. After restarting my computer, however, I found that the trojan still remains (and I'm still getting periodic notices from Avast mentioning that it is quarantining the file). I have also since installed AVG as recommended by a friend of mine, and I'm currently letting that run a scan as well. If a log from that would be needed, let me know and I'll be sure to post the result.

And before I forget, I'm running Windows 7 (64 Bit edition), and I normally use Firefox. I apologize in advance if this is problem that has been posted before or if I'm leaving out any other information, but I'm really not so good when it comes to PC troubleshooting as you can probably tell.

Thanks in advance. :>

So I just finished my scan with AVG and being new to using it I wasn't sure how to get logs from it, but there were two files that I had been unable to move:

c:\Windows\assembly\GAC_32\Desktop.ini Trojan horse BackDoor.Generic15.AXLA

c:\Windows\System32\services.exe Trojan horse Dropper.Generic_c.MMI

I tried to remove the first file, but then I had a prompt from AVG asking if I wanted to forcibly move the threat and that it would risk system stability or even cause a crash, so I decided against it for the moment. The second file however, was deemed white listed and AVG wouldn't allow me to move it. So, I'm unsure what my next course of action should be, and any help in fixing this would really be appreciated.
