noticed today that YouTube wouldn't work on chrome, forefox or (god help me) edge. after some investigation i checked adguard and it was trying up update but seemed to be failing at doing so. I uninstalled it and youtube working fine. I reinstall adguard version 6.4.1795.4865 RC and youtube now works BUT... the update that it says it available and you can see it downloading it then start to apply the update then the UI disappears. Looking at running processes while this happenes it goes from 4 processes to one - Adguard for windows 32 bit. If i then go into start/programs/adguard the UI reappears and the update still comes up as available but to press the update button is to rinse and repeat any advice?
