Okay then........I say if it ain't broke don't fix it.
I don't see any malicious files or entries in the ComboFix log, or anything remaining in the MBAM log, and you say you aren't being redirected and that it's running well. Maybe all it needed was this last touch to do away with the problem.
I'll leave the thread open for a couple of days to be sure the problem doesn't return.
Please delete ComboFix and the folder it made C:\Qoobox
, empty your recycle bin and reboot. I'm sure you already have, but I have to say this just to make myself feel better.....make sure you have AVG reinstalled and running.
Let's clear all the restore points and set a new and clean one :
Click Start Menu > Run > type (or copy and paste)%SystemRoot%\System32\restore\rstrui.exe
. Choose Create a Restore Point
then click Next
. Name it ( something you'll remember) and click Create
, when the confirmation screen shows the restore point has been created click Close
Next goto Start Menu > Run > typecleanmgr
, Disk Cleanup will open and start calculating the amount of space that can be freed, Once thats finished it will open the Disk Cleanup options screen, click the More Options
tab then click Clean up
on the system restore area and choose Yes
at the confirmation window which will remove all the restore points except the one we just created.
To close Disk Cleanup and remove the Temporary Internet Files detected in the initial scan click OK
then choose Yes
on the confirmation window.
