//Normally Kaspersky checks a program's trust rating the first time it launches. There's an option to scan and check all programs when turning on this feature, an initial investment of time that will pay off in speedier operation later.
Known and valid programs naturally receive full trust from the firewall, allowing all reasonable access to the system and the network. Known malware is, of course, untrusted, other programs may be labeled Low Restricted or High Restricted. For these programs, certain actions are forbidden, while others are permitted only if the user confirms it's OK.//
Bernie there is no doubt that Kaspersky is very good. Is it possibly a setting issue for you to investigate. The above was from a review site.
