Got this issue repeatedly, so i have to alt + ctrl + del to close it again,

This happen every time i join in the room, not freeze directly but awating some minutes, and also if someone sending message to me, will be freeze, so i have lost many times to play a game

I have clear uninstall voobly, and also have run anti virus and mallware, everything good

Please keep in mind, that this directory also exists for different game mods, e. g. Wololo Kingdoms or 1.6 Game Data. You must clear those directories as well. That should fix the issue.

If the problem persists, please perform a clean installation of the Voobly client:
