Yes, the free combo is the Comodo Internet Security Premium.
If you mean healing a Windows system file, i.e. remove the virus and leave the cured file alive then CIS cannot do this - it just deletes an infected file. I do not know if the Comodo Cleaning Essential can do this, may be other guys can say about the CCE.
Why not install a backup & recovery software, they are free ones available? And then do regular backup of the system drive and restore a previous image of the system in case of infection.
Hi littlebigman,
All installers have the same capabilities after install whether it be the Antivirus/Firewall you will have the option without downloading another installer.
Go to the Start menu>Comodo>Comodo internet security>Add/remove components>Next>Change (See Screenshot) and tick the components you require then click next to continue.
Alternatively go to the Control panel Add/remove programs and proceed from there.
Note: It is recommended to run both components from the same installer.
