I'm not sure Comodo knows what portable means.
I'm not sure that any company knows what portable means. Or even if they want to know. I don't get it...they could potentially double the number of users if they'd offer a portable alternative to their software (i know sometimes this is a very hard thing to accomplish but they don't even leave the impression they try). And wait, there's more: some (like Google) struggle to find the deepest path of installation into the heart of OS. This is behind my comprehension abilities. Someone should tell them that portable settings = future.
To be truthful, I'm skeptical about anything from Comodo after using their firewall ... since using theirs I had an infestation.
I can't second you on that. I have Comodo firewall and Avira antivir (free) combo for some time now and never got a problem (occasionally i scan using SpyBot and AdAware free).
Hope this helps somebody
Helps me a lot (to stay away from it for now)
