Comodo Firewall will not install

I have download 3 different version of Comodo Firewall, however I cannot get it to install. I have removed Norton / Symantec Internet Security 2007, as it stopped working, but now I cannot install Comodo FW as a replacement.

I have also had a I Worm Beagle ij Trojan on my PC, which I’m trying to clean off. Also flec006.exe, which AVG Anti-Virus has cleaned.

I also cannot run some programs, I get fro example errors such as “firewall.exe is not a vali Win32 Application”

Can anyone help, I am also loosing Internet Connection intermitantly?

I have download version, and, all do the same, they look as though they are going to run and extract installation files, then nothing, back to the windows desktop and no program has been installed???
