Startup problems uninstall problems

Suddenly Commodo internet security will not start. It happened shortly after an update. Tried reinstalling to no avail. Cannot uninstall as it doesn’t show up in the list of programs to uninstall. Looked in the Commodo files and no uninstall there either. Any help appreciated.

Look: С:\Users[u]All Users[/u]\Comodo\Installer
Whether there is there msi the file.
Try to start.
Note: This folder is hidden. Include in properties of the folder: To display the hidden files and folders.
Also remove a mark: To hide the protected system files.
