Well £95 later I have my HP back.
It was reset to factory settings as it was seriously infected ,and all my files were encrypted ,I couldnt open anything in the end ,couldnt even get past the opening stage.
I wondered if it was worth keeping this laptop going but I love it (when not infected that is).
Why didnt Avast stop this ,or are some things too much for any virus ware?
Very fed up at the mo
