seeking malware removal help

Hi. I have had ongoing problems with my Acer netbook for a long time now. A few months ago, I ran three different antivirus programs and only SuperAnti-Spyware was able to detect a virus, a trojan. But a few months later, my regular anti-virus, Avast, stopped working and my computer won't let me download it again, nor will it let me download any other antivirus or firewall program. So something is preventing it from working. I also can't download the new version of iTunes, flash or other program updates i've tried. I always get errors. Aside from this, the main indication I have that I have some kind of virus is that the sound on my computer is messed up. You can hear it even in the startup sounds. There is always some kind of delay and crackling sound in part of the sound that is supposed to be played. (I hope this makes sense...it's hard to describe.) Last night I ran ComboFIx and came here to seek help understanding the results and what to do next. I followed all of the instructions and ran all of the scans. Please note all scans were done AFTER I ran ComboFix. Please also note, while Avast won't open and I have no icon showing it working on my computer, ComboFix kept telling me Avast was working and that I had to disable it. But I could not disable it since I am unable to open it at all. Thanks SO much, in advance, for your help!

 

Here are my scan logs. I can only upload 5 so i can't add the combofix one...

 

here is the combofix log. please let me know if you need anything else. again, i really appreciate the help!

 

the registry keys found by roguekiller were not malware? do i need to do anything about them. in any case, thanks and i will do as you said and will report back.

 

OK, all done. Attached is the requested log.

 

I just deleted it manually. Is there some other way I should be doing it?

I didn't try re-installing Avast because you told me not to do so yet. I can try now.

I realized from the un-install process that what had not been functioning on my computer was the Avast interface. When I clicked on it it would tell me it didn't have the right configuration. But what I found out from using Revo was that it was actually there and had been working all the time even though I never saw the icon like I used to.

Anyway, I will do everything you instructed now. Do you need a log from ccleaner?

 

sorry, i had deleted the folder's contents but not the folder. gone now.

also...avast has re-installed! so yay, thanks!!! at least one thing is back working properly now. of course, when the avast lady (before i changed my settings so it would no longer talk to me, which i hate) told me my computer was now protected, her little speech was completely messed up by my computer's audio problem that i believe (because i was told long ago when a similar thing happened and it turned out to be true) is indicative of this virus i can't seem to get rid of...

so, yes. all these steps are now done. next step?

 

hi. everything is really running the same, unfortunately. problem with the sound continues, and computer won't let me install flash or itunes--both programs it has downloaded with no problem in the past. if it's not malware, could it be something else?


i tried to uninstall hijackthis but i didn't see it on the list. we didn't download it for this, right? so is it something you saw in my logs? how can i get rid of it?

i r-Renabled Disk Emulation software with Defogger and ran the mg registry file.

but when i clicked on MGclean.bat i got an error and then the entire contents of the mg tools folder disappeared. is that what was supposed to happen?

thanks again for your help! not sure if you have any other advice on figuring out what is wrong and/or helping me try to fix it but...i'm open to suggestion! thanks!

 

it's gone, so i guess we're good. thanks again for your help!

i'll have to try to find out what else might be at the root of my problems.

two more questions, though:
1. so did we not, then, find any malware on my computer after all?
2. what about the registry items found by roguekiller?

 

ok, well, i really appreciate your help! take care!
