The free anti-virus that is installed on our desktop had an expired registration. The message said that we have to purchase a paid version of Avast. And since Avg wouldn’t run under Windows XP, we are now looking for another anti-virus that is free from the internet. Do you have any suggestions? I am actually looking for suggestions based on their experience and not just what you had searched for I can also do a search. What I need is the review. Thanks to those who will respond.
