Even though I added Winpopup LAN Messenger to "Exclusion" on Eset Smart Security, it still blocks it from communicating with Winpopup LAN Messenger on my network. I even added the program folder such as "C:\Program Files (x86)\Winpopup LAN Messenger" in the "Exclusions" on both my computers whose running Eset, but no luck. However, if I turn off the firewall on eset, everything works fine. Any help would be appreciated P.S: the messenger does not access the internet at all, just little program that helps communicate within the network... THANK YOU IN ADVANCE and ESS FTW, ITS LIKE NO OTHERS!
