Once upon a time I tried Comodo firewall but did not keep it. When I uninstalled it I didn't manually search the registry for stray entries related to Comodo. I did however run my registry cleaners to see if any of them found invalid entries left by Comodo. No entries were flagged by any of the three registry cleaners I have. Today while doing a manual search in the registry I found several entries related to Comodo. I am wondering if they are safe to delete since the application is no longer on my computer. I did run all my registry cleaners again just to see if any of them flagged the Comodo entries as invalid and none found them to be invalid. Here are the registry entries in question. Should I remove them or am I better off leaving them be?
