Please put ComboFix directly on your desktop, not here:
Running from: d:\my documents\downloads\ComboFix.exe ---> it should be here:
C:\Documents and Settings\Aba\Desktop\ComboFix.exe

I strongly advise you to cleanup your Desktop. Remove everything but links to run programs. Do not download and save programs here and definitely do not use it for long term storage. You need to keep ComboFix.exe here for now as we need it, but we will be removing it when we are finished with your cleanup. A cluttered Desktop is malware's playground and it can also cause performance degradation especially when you start saving large files here like you are doing.

I am not seeing any malware or MBR infections in your logs. You need to tell me exactly what Avira is reporting......the exact paths!
But you have since removed them from quarantine. You did the right thing to quarantine them. So I can only suggest that you keep Avira updated as well as your other AS programs.

If you are not having any other malware problems, it is time to do our final steps:

1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no real-time protection. They are useful as backup scanners.They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
   
   • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
   • "%userprofile%\Desktop\combofix" /uninstall
     
     • Notes: The space between the combofix" and the /u, it must be there.
     • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
4. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
5. Go to add/remove programs and uninstall HijackThis.
6. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders related to MGtools and some other items from our cleaning procedures.
7. If you are running Vista, Windows XP or Windows ME, do the below:
   
   • Refer to tahe cleaning procedures ian step 3 the READ ME for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
   • Then reboot and Enable System Restore ato create a new clean Restore Point.
8. After doing the above, you should work thru the below link:
   
   • How to Protect yourself from malware!

 

First off, you are most welcome.

Now, I suggest that you also keep SAS. The rest of what you have is fine. Windows Defender will not harm anything if you want to keep it. Quarantine is the best way to go, as sometimes what is removed could be a false positive and do harm, so you want to be able to restore items in quarantine if such an occurrence happens.

I suggest you install this:
AutoEater.

Then make sure all your protection software is up to date. Then run MBAM, SAS, and then Avira on that external drive.
