I've been using for many years, very happily. At the moment I use AVAST premium for 2 minutes, then the system goes down, then for another two minutes, then it goes down again, and so on and so on. I've contacted you for some help, but no-one has responded. I see from the various discussions on this and other forums that this is an issue you don't seem able to fix. Should I just give up now and find another provider? Thank you.
