Since yestrday when I reopend my laptop and as soon I connected on internet my whole pc hangs and not even ctrl+alt_del working. I cheked several times and came to conclusion that as soon as I connect to intrenet vista hangs, then I disable the avast and restat the PC its working fine. Anything that I can chek in avast so that it works properly. I have avast 4 free ver and using it more than a year till I face prb yestrday.
