I recently bought MKS_VIR 2004 from the English distribution channel in US http://www.stormbyte.com
I viewed all the options, tools, update features, and quarantine features. I stumbled on an feature that is not documented in the instructions manual.
When there is a Critical Virus alert MKS_VIR 2004 has this handy feature integrated into the software. MKS everyday once a day connects to the server to check for a regular update. In the mean time every couple of minutes there is a request sent to the server if there is a emergency update available in case of a virus outbreak. Once the server responds that there is an update the program immediately downloads the new updated virus definition.
To all the people that have a firewall up and using MKS_VIR 2004 you need to allow mks_menu.exe to connect using UDP on port 2000 to have this feature enabled.
