I'm going to try to explain this as quickly as possible, even though there is a lot to say.

It all started yesterday when my computer shut itself down. I don't know why, but my computer was suddenly overrun by some fake virus scan programs (I don't remember any names, it happened very quickly, and rather unexpectedly) that began to create random .exe processes, ones with names like 1ODEF4G.exe or something with seemingly random filenames like that. They overran and bogged down my PC within a minute, and Windows actually shut itself down. It restarted to a blue screen saying that Windows had shut itself down to avoid possible damage, and it listed some other info I cannot quite remember.

Figuring something was very wrong, I ran a search right away with Malwarebytes AntiMalware Software and it detected numerous (54?) infections and trojans. The computer was running smoothly at this time and the program said it would have to restart the computer to complete the removal. I accepted, and once the computer had restarted, that's when the real trouble began.

My computer has had some errors in the past, and I've had help on other PC Fix It forums from posting my HiJackThis logs; the most recent left me with an annoying but non-threatening need to have to manually start explorer.exe. I mention this because when my computer restarted after the Malware scan, Spybot S&D appeared right away and started running it's own scan. I have not used that program in awhile and I have never had it do an autoscan, so I closed it, wondering why it would do so now. After I did that, I manually started explorer.exe and that's when my computer slowed to a crawl, one so slow, that it was practically frozen. The Task Manager showed 100% CPU usage, and I was never able to get anything done. It still does this if I turn explorer.exe on.

I thought it might have been something to do with the Spybot Search, so I restarted the computer and let it complete the search on the next start-up, but that didn't help at all. Running the computer in Safe Mode is fine, and I ran a Virus Scan search with Avira AntiVir, and another Malwarebytes scan, neither of which seemed to help the problem. I did update the Avira recently, and it had to uninstall the old version, and when I set up the new one, I chose the "extreme" (I use this term because I don't know the real one Avira uses) protection, which stated provided the most protection but would noticeably take longer on start-up. I thought that might be the problem, so I uninstalled and reinstalled Avira in Safe Mode, this time choosing the normal protection, but that also did nothing to help the problem.

I also ran Combofix, and while that fixed the problem of not having to manually start up explorer.exe, it did not help anything else.

The only way I am able to post this right now is by using a work around; I open Task Manager instantly when the computer boots and close explorer.exe before my PC freezes, and I choose to start a new program, and input firefox.exe.

I know this probably isn't the best way to be operating, but my father absolutely needs this computer to do his daily work, and using this workaround, I am able to let him use Adobe Audition without the computer freezing at start-up.

I believe I have explained everything, and I really hope someone can help me with this confusing and crippling problem. I will not visit any potentially harmful sites while using this workaround, only the BleepingComputer forums and my Gmail account.

I will attach a HiJackThis log as I cannot run the dds script without starting explorer.exe, and freezing up my PC. I will also try to attach my Combofix, Malwarebytes, and AntiVir logs if I'm allowed to do so.

Thank you in advance for any help given

Oh, and before I forget, I had saved on my desktop a text document named bgsvcgen because it was a process unknown to me that occurs at start-up (which I always instantly shut down), and looking it up on Google showed unfavorable results, so I figure it might be useful to mention.
