DieSse Thanks for your two posts. I,ve just been reading the comparatives and come to the conclusion there is very little difference. At least I now know. Will tick this as resolved. If my daughter ever has any probs I will let you all know.
Let`s not get paranoid about the tests sponsored by various people. AVG Free is probably on the same base level for their free edition as well as a few others. If you are worried about it just pay Norton or Mcafee £30 - £40 for their offerings. I personally have never known a "Home User" who has been let down by either AVG or Avast. (With a bit of common sense applied)
