Hi,
I had Avast free since 2008 on my old PC. New one last year came with Norton Internet Security, so for the sake of £15 I registered it. However the year is nearly up so I am thinking about returning to Avast (probably free). However I quite like the idea of the integrated AV, firewall and antispam.
If I were to go for any Avast product how do I go about completely ridding my system of all traces of NIS?
