Hello byodasa and welcome to TSF,

Please print out or copy this page to Notepad since you will not have any of browsers open while you are fixing this. Make sure to work through the fixes in the exact order it is mentioned below. If there's anything that you don't understand, ask your question(s) before proceeding with the fixes. Again, you should not have any open browsers when you are following the procedures below.

Go to My Computer->Tools/View->Folder Options->View tab and make sure that 'Show hidden files and folders' (or 'Show all files') is enabled. Also make sure that 'Display the contents of system folders' is checked.

Download CleanUp! (Alternate Link if main link doesn't work) and install it. Do not run it yet.

Restart your computer and boot into Safe Mode by hitting the F8 key repeatedly until a menu shows up (and choose Safe Mode from the list). In some systems, this may be the F5 key, so try that if F8 doesn't work.

Run a scan in HijackThis. Check each of the following and hit 'Fix checked' (after checking them) if they still exist (make sure not to miss any):

O4 - HKLM\..\Run: [aqcufwv] c:\windows\system\aqcufwv.exe

Delete the following file:

c:\windows\system\aqcufwv.exe

Run CleanUp! and click on CleanUp! button. When it asks you if you want to logoff, click on Yes.

Reboot into Normal Mode and run another scan with HijackThis. Save the log and this time, post the un-analyzed log.
