Firewall Problems on blog

I’m new to comodo -it was installed after a particularly nasty virus infestation. I run a blog and since this has been installed, my people are unable to comment. Is there a setting that I need to change in order to make it possible to get messages? Thanks for any help!

are you running a server? if not it has nothing to do with your computer. Check the settings on the blog to make sure comments are allowed.
