I have KIS 2013 running pretty well on one of my desktops. One setting I made was to uncheck the "trust applications with digital signature" which is checked by default. Also I made a setting change to move unknown applications to untrusted. I also disabled the web, mail and IM antivirus and also disabled anti-spam. I noticed under the anti-banner settings there is a setting to have IP addresses resolved to domain names. Is there a similar setting for the firewall / network monitor connections? Any other tweaks to KIS 2013 people would like to share?
