Thank you for taking time to respond, Earth. I finally decided to install Comodo Firewall and disable HIPS in Eset. Everything OK, only functions like active memory scanner and anti-exploit were disabled in Eset as they are part of the HIPS block in Advanced settings. I did this mainly because of the fact that Windows firewall could be meddled with as it has no active self-defense, and as part of the OS, probably it is prone to vulnerabilities. Otherwise I like ti very much as a firewall, it's a great protocol filter! And this is primarily the job of a firewall. I really tried to find a similar 3rd party firewall for Windows 8 - firewall only, no HIPS and other bells and whistles - but I couldn't. If Look'n'stop was actively developed and was fully supporting Windows 8, probably I would have installed it together with NOD32.
