After completely uninstalling Comodo, Windows Security Center reports that Comodo Firewall Pro is on...
Easily fixed. Go to run and type services.msc. Then find the WMI service ( Windows Management Instrumentation) and stop it. The go to C\Windows\System32\Wbem and delete the Repository folder and then reboot.
This should do the trick if you're using Windows XP. It worked for me many times with other security programs that remained in WSC. If you aren't using Windows XP, then perhaps you can google for how to do it on other systems like Pro or Vista. * Start>Run>services.msc [enter] Or go to start menu, Control Panel, Performance and Maintenance, Administrator Tools, and then services. * Scroll down to Windows Management Instrumentation and double-click it. Now click on the "Pause" button. Leave that window open and double-click My Computer. Navigate to %systemroot%\Windows\System32\wbem (where %systemroot% is the drive where XP is installed). Delete the Repository folder and *only* the Repository folder. Now go back to the WMI service window you left open and restart the service. * This will rebuild the Repository and hopefully straighten out the incorrect entries for all your duplicates. * In order to see the Windows files, you may need to unhide them: * Make sure you are able to see all hidden files and extensions (View tab in Folder Options). o Check "Display the contents of system folders". o Check "Show hidden files and folders". o Uncheck "Hide protected operating system files" and click "OK" to the dialog box.
