Hi!
I installed Windows 10 Technical Preview version , which was released yesterday. When i tried to install Avast 9.0, the process was aborted and i got Microsoft notification saying ‘there’s compability issue with Avast Antivirus 9.0’. I even turned off Windows firewall in case it was trying to prevent installation. Didn’t help.
Because of this, i don’t have any antivirus software on Windows 10 . I also have 1-year license for Avast VPN tunnel, which i also can’t use now. :-\
Hope this problem is solved soon!
