Hello,
First thing first, update Kaspersky to the Kaspersky Internet Security 2014 version, and uninstall Comodo Firewall. As you may know, most Internet Security suites come with a firewall, so you do not need another one.
There are other things that you can do to improve your PC security, but this is the first thing that you should take care off as this may cause slow-downs, conflicts and other errors.
