I've seen a lot of discussions about this on various forums lasting many months. I got a new PC yesterday and installed AVAST using my licence (which runs until November 2018). Ironically i just renewed it on the old PC when the whole PC crashed and died. So I have 51 weeks left on a licence - BUT i can't use the licence as it keeps going down. I've tried the repair - as suggested by others - I've also uninstalled and re-installed and uninstalled and re-installed... but to no avail. Has anyone managed to find a solution, or should i just be giving up, asking for my money back and moving to another provider? Avast has been great for the many years I;ve used it, until now. I've contacted the help centre, but had no response. I use Avast Premium, but i also tried installing the free version and the same thing happens. Help!
