In normal mode Windows XP crashes after login, the reason given is inspect.sys. If I remove inspect.sys from the Windows/System32/Drivers folder I can start in normal mode (but of course it reappears).
When I then tries to remove Comodo (after stopping it) via the Control Panel I get a message saying that there is a network error trying to read from the file C:\Windows\Installer\CIS.Setup.msi. There is no folder C:\Windows\Installer on this hard disk.
I can use Internet Explorer and Thunderbird, but not Firefox, which hangs when loading data.
I have downloaded CIS again trying to reinstall, but the install crashes.
CIS version 5.5.195786.1383 and Windows XP Home edition SP3.
