  I have a similar problem. I tried to uninstall Comodo Internet Security and Comodo Firewall from my computer. I used Windows remove program utility and tried several other uninstall programs from the Internet. When the dust settled, I had this folder: C:\Program Files\Comodo\ It contains a half-dozen files with gibberish names. When I try to delete one of these in Windows or the Command Prompt I get an error message, "Access Denied." I tried giving myself access, but it didn't work. I am not familiar with Administrator and User procedures. I am the only one who uses my computer. When I try to uninstall with Windows, it gives me a message that the install program cannot be started on a 64-bit machine and that I should download the 64-bit installer from Comodo. At the Comodo site, they only have one installer, which is labelled 32-bit & 64-bit. It's the one I used originally. Helllllp!
