I have questions about a system (Asus EeePC netbook) with Windows XP Home, Avast Free Antivirus 2015, and Comodo Free Firewall version 220.127.116.1126.
I know that Windows XP is not supported anymore by Microsoft, and thus subject to unpatched vulnerabilities exploits, so I’m trying to make the system a little more secure (while being extra careful when using this netbook, e.g. by not reading e-mails). That’s why I have installed the free firewall from Comodo.
I have the impression (not sure) that the Comodo Free Firewall has some features which are normally found in antivirus software. Is this true?
I think I’ve read that this antivirus-similar functions are used just to protect the firewall itself. Is this true?
I am concerned that this antivirus-similar functions could conflict with an installed antivirus, in my case Avast Free Antivirus 2015. I think that this would be strange though, since a firewall should normally be designed to work together with an antivirus (which should be installed on most systems), and the programmers from Comodo should have thought about this.
I read some posts suggesting to configure mutual exclusions between the two programs (but they were old posts from years ago, I think on the Avast forum).
But is this really required? Sounds strange that Comodo Free Firewall would be designed in such a way that it conflicts with an antivirus by default (since an antivirus is installed most of the times).
Should I just leave both programs as they are, or do you suggest to tweak their options?
What do you think about this conflicts issue?
