This is also the same issue I was experiencing with v6. I would notice that the entire computer would freeze when the Comodo firewall was asking me what I wanted to do. Also, I noticed that it no longer makes recommendations on the applications when you get the popups. I do consider myself technically savvy however I like to have a warm fuzzy that the checksum of the presented executable or module is, in fact, considered safe. I don’t like the program to make the decisions but I do want the program to at least give me some advice like with the v5 firewall.
By the way, only use HIPS and the Firewall- I don’t use A/V because there are better products out there on the market and I’m very concerned with rootkits.
Please fix the product and release a version that doesn’t feel like a beta version.
On another note, I do want to say thank you for allowing us to have such a powerful firewall product for free. Your app, according to Matousec.com, is one of the highest-ranking firewall products on the market! :-TU
