When downloading Google Chrome I somehow also downloaded COMODO Internet Security. After several attempts I thought I had removed COMODO using the windows add/remove program. When I restarted my computer I got the message unable to start COMODO. Apparently COMODO is still in Program files/COMODO. When I tried to delete the file I got the message “unable to complete request because COMODO is in use by another program. I have no idea what program is using COMODO and would very much appreciate help in completely removing COMODO Internet Security from my computer.

Thanks Jessie

How to Uninstall Comodo Internet Security/Comodo Firewall (CIS/CF)

When I tried to delete the file I got the message “unable to complete request because COMODO is in use by another program.

Most likely there are services relating to COMODO which need to be stopped/disabled because they are in use. You can disable them, reboot in safe mode and then remove any left over folders.

Anti-virus software components insert themselves deep into the operating systems core and create files/folders/registry entries in various locations. If is not uncommon for some anti-virus programs to not completely uninstall itself using the usual method of Add/Remove Programs or Programs and Features in Vista/Windows 7. In many cases anti-virus vendors provide clean-up utilities on their web sites to remove remnants left behind after unintalling or for a failed uninstall so always check there first.

I was able to find this but cannot vouch for its effectiveness: Uninstaller Tool for Comodo Products

I had this problem also and found the following process by trial and error.

 

Start in Safe Mode
Rename the following files to something else. (eg change ext to .x) 
system32\drivers\cmderd.sys
system32\drivers\cmdguard.sys
system32\drivers\cmdhlp.sys
system32\drivers\cmdide.sys
rename the following folder
c:\program files\comodo
 
restart in normal mode
 
Rename the files and folder to their original name
system32\drivers\cmderd.sys
system32\drivers\cmdguard.sys
system32\drivers\cmdhlp.sys
system32\drivers\cmdide.sys
rename the following folder
c:\program files\comodo
 
Run Uninstall all Comodo entries from Control panel
Viola!

That may have worked but you shouldn't have to rename files/folders to remove the software.
