I recently installed a Video downloader.
I was not happy with its behaviour, so I tried to uninstall it using CPM 1.3.2.30. The option was for a Standard Uninstall. Immediately the uninstall started, a message popped up saying that in order to complete the installation (it may have said removal) the PC needed to be restarted. Although I felt it was all a bit fast, I said yes. The result was that the application remained in place after restarting. This happened 3 times.
In each case, I had to re-start CPM in order to have another go, as it seemed to freeze, even after I had hit the Cancel button to end the uninstall.
Comodo IS also sandboxed a process connected with the uninstall. Looking at Defence listings, it appear the boxed app was related to the uninstaller of the app, and not CPM.
After the first failure, I had to use another app that had a Forced Removal option, which just removes all references, pretty much regardless of what the installed programme tries to do. This option does not seem to be available in CPM.
I have tried installing again and the uninstall seemed to work using CPM, without that restart message.
The difference is that I now have Web access, which I did not have when the uninstall failed. I had no access because, in reaction to the behaviour of the app, I stopped all services using CIS. So it would appear that if the app cannot get to its site, it causes this uninstall failure.
I just thought that this may present a loophole, as it did allow a programme to refuse to be uninstalled.
