Can you please do the following.


===============

Scan with HijackThis and then place a check next to all the following, if present:


F2 - REG:system.ini: Shell=Explorer.exe regsvr.exe

O4 - HKCU\..\Run: [Msn Messsenger] C:\WINDOWS\system32\regsvr.exe

O7 - HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System, DisableRegedit=1
...(Unless you've restricted the use of registry editing, have HiJackThis fix this.)


Now, close all instances of Internet Explorer and any other windows you have open except HiJackThis, click "Fix checked".

===============

Locate and delete the following item(s), if present. Make sure you are able to view system and hidden files/ folders:

files...

C:\WINDOWS\system32\regsvr.exe


-

Note that some of these file(s)/folder(s) may or may not be present. If present, and cannot be deleted because they're 'in use', try deleting them in Safe Mode by doing the following:

• Restart your computer
• After hearing your computer beep once during startup, but before the Windows icon appears, press F8.
• Instead of Windows loading as normal, a menu should appear.

Select the first option to run Windows in Safe Mode hit enter.

-

Reboot.

===============

After rebooting, rescan with hijackthis and post back a new log. Please let me know how your pc is now.
