Can you please do the following.
===============
Download the newest version of HiJackThis ; version 2.0.2. Place it in a permanent folder before scanning. Repost your log after following the steps below. This version has features that might be more helpful in 'cleaning' up your system.
===============
Let's look for, and delete, any program segments (prefetches) that might be present, and are associated with the 'problems' we're trying to remove from your PC. To do this, let's:
1) Click "Start | Search", then search for each of these program's base name(s), in all files and folders:
zngkmg.exe*
2) Then if any are found in the 'prefetch' folder, delete them.
Look closely, since the 'base' name will have a bunch of random numbers and letters attached to it.
===============
Run HiJackThis then:
1. Click "Open the Misc Tools Section"
2. Click "Open Process manager"
-
Next, while holding down the CTRL key, locate (if present) and click on (highlight) each of the following:
C:\WINDOWS\system32\zngkmg.exe
Now double-check and make sure that only those item(s) above are highlighted, then click "Kill process". Now, click "Refresh", check again, and repeat this step if any remain.
===============
Scan with HijackThis and then place a check next to all the following, if present:
O4 - HKLM\..\Run: [Microsoft] zngkmg.exe
O4 - HKLM\..\RunServices: [Microsoft] zngkmg.exe
O11 - Options group: [INTERNATIONAL] International*
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\zngkmg.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.
