CPF 2 evidently did not like the new version of Dell’s Support Center software. I possibly made a wrong choice on a popup alert too, and I have never found it easy to back out things with Comodo. (I know a number of people who have stopped using it because of this.)
So, I tried the typical Windows fix and uninstalled Comodo. 3 was available so I installed that.
Most things work just fine, but I can’t send e-mail. (Thunderbird using SMTP over SSL).
The info listed in another thread here worked:
…
3 - Email client problems
- Firewall->Tasks->Stealth Ports Wizard
- Select “Alert me to incoming connections”
…
I have no idea why this would solve the problem, it isn’t even logical.
I didn’t do the second part of the instructions.
…
Then Protocol analysis should be disabled.
- Firewall->Advanced->Attack Detection Settings->Miscellanous
- Uncheck “Do protocol analysis” option
…
One of the things I tried doing to solve the problem was to define Thunderbird as a trusted app. That didn’t work, and then I’m back to the old Comodo problem - how do I undefine a trusted app.
How do I reverse mistakes without re-installing? In some cases, how do I even find what has been defined and what hasn’t?
