Well done mat for suggesting this !! Just removed Avast one free version and .... bingo.!!! The pc now operates on USB and WI-FI . I have gone back to defender plus AVG free. All working again. I looked at your link in the post and tried to follow the instructions , but could not do so , as avast would not allow the unblocking options .... unless you have bought the premium version. So off it came. Shame really as i was happy otherwise. See how i go on again with this. Surely defender plus AVG on a secure private network should be ok , but i did have problems sneaking in last time ! thanks again ..
