Removing a "Trusted Publisher" from Internet Explorer and Office 2007

harin35,

Let's check the Registry...

Please download SystemLook:
http://jpshortstuff.247fixes.com/SystemLook.exe
Save to your Desktop.

Right-click SystemLook.exe, and select: Run as Administrator

Copy all the content inside the following quote box into the main textfield of the program:

:reg
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domain
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Ranges
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Ranges

Click the Look button to start the scan.

When finished, a notepad window opens with the results of the scan: SystemLook.txt

Please post SystemLook.txt in your next reply

Also try the following:

Press the Windows key and the R key at the same time
In the Run prompt, Copy/Paste: certmgr.msc

Is Comodo Security Solutions there?

You can find the serial number of the certificate by right-clicking the certificate, and selecting:
All Tasks > Open > Details > Serial number

Next, open a Command Prompt, and copy/paste the following at the blinking cursor:

certutil -delstore trustedpublisher serial number

(You will need to provide then serial number at the end!)

Press: Enter

Glad it worked!!
