Hi Arthur
I read in another thread that you had taken your laptop in to P C World to have a new Norton anti-virus programme added.
If you are using a Microsoft system like Vista XP or Windows 7 then you can easily get their" free"
Security Essentials.
I have it on two computers and it works fine and does not run out and need renewing, and did I say it is "Free"
Happy computing,
Mick
