virus/malware help!

Any help would be greatly appreciated.

I began having issues about a week ago... Here is basically what happens:
The problem began with me getting a pop up message telling me i was infected - it was a type of window that Windows would use to alert you, but was obvious to me that it wasn't ... I immediately closed everything and did not click on anythign else...
Now...
Internet explorer and Firefox crash constantly - Firefox especially (which is what I mainly use) when going to normal websites that i reguarly visit [ie, checking email, bank account, facebook, etc]
With Internet Explorer, when I do searches [via google] and click on links, I am often instantly redirected to some sort of ad page but then can tab back to the page I was trying to reach.
I've also noticed that my Norton 360 which had said it expired [and to me it seemed like it was reasonable that it had] about 2 days before this all happened... now all of a sudden says it is active again for 45 more days?? However, it doesn't show up in my desktop tray anymore instnatly, i have to actually open the shortcut for the main page from my desktop. Also yahoo and myspace IM that always auto started upon start up no longer do.

I had tried using Avira and it said it found a virus... something like blumblebee and would say it removed it, but upon another complete systom scan would continually find it again.

I've gone through all the steps and have attached my logs.
I had issues with Combofix - i couldn't get the program to download or go to any of the bleepingcomputer webpages at all - they just didn't load. I tried Firefox and when I attempted to save it to my desktop got a message that said "C:\Documents and Settings\******\Desktop\combofix.exe.part could not be saved, because the source file could not be read.

Try again later, or contact the server administrator."
with my first and last name [computer name] as the ****** part
Then it appeared to download.... but upon trying to open the .exe file, got no response at all. after trying to delete the original and re-download it, had no success adn again received the same message above.

Also. while using MGTools, I only got 2 logs, I did not get the newfiles.txt log at all.

Thanks so much
Let me know if I can clarify anything

Getunkey.txt was too large to upload with this set so i'll upload it separately

 

here is the other log...

woops.... this is the message i get
"GetUnKey.txt:
Your file of 399.1 KB bytes exceeds the forum's limit of 250.0 KB for this filetype. "
???? What should i do?

 

Thanks

With MGTools it just stopped after it created those first 2 files. I left it be for hours and it never did anything else - no error messages, never got the HJT prompt..nothing.

I'll try the other thing you suggested tonight and post what happens

Thanks

 

Attached is my Avenger log.

I ran into the same problem when running MGTools. I just stops when it goes to process the 'new' part... just never does anything after that. I let my computer sit for 12 hours and still nothing. No error messages, program stays open, but nothing happens.

 

Here is the DrWeb log
