Uninstalling v2.73 has not been a straight process due to the "unkillability" on my system of some residual WSVX process after exiting it in sys tray. Again, this ocurrence was displayed in Process Explorer Gui, but not in windows Task Manager. A workaround has been to 1. Display WSVX gui, 2. in settings, uncheck "Prevent WSVX to be killed" and 3. exit WSVX from the systray. Then, after installing WSVX v3 and rebooting, I ran into several issues (system hanging/frozen). The sole way I found was to hard shutdown my pc, reboot in safe mode, uninstall WSVX, reboot in normal mode, reinstall WSVX, reboot, much of the time with the same hanging problem after that. A workaround for that has been to install WSVX v3 in safez mode. Or maybe I just had luck?? In the process of all that, I lost all the exclusions I had gradually set up these last weeks. So, I suggest you give the user a mean to export/import them. Concerning new features, I tested mostly the firewall. Very interesting to have that. There are little Gui problems though: in the field for rules name, I can paste a name with blank characters, but can't type blank characters when using the keyboard. Moreover, the "export" feature doesn't work well. Immediately after rebooting and connecting, WSVX let me know that some app was trying to access the internet, asking for a decision on my side (blocking/allowing). In that precise case I knew that the connection could be done, but more generally, the user's decision would be helped if WSVX specified to which ip or url the app tries to connect.
