Ghost generally is a good program m8, but I think, as Norton releases a new version of their software, there's a newer way for it to fuck your pc up.

Firewall, Norton Internet Security or Personal Firewall, Blackice PC Defender, McAfee are good

I attended a job the other week, guy bought norton internet security 2005 and got go back free, installed it, told him to restart his pc and it's goodnight from microsoft.

Couldn't do nothing with it whatsoever, had to format it and put xp on again

Hence why I'm sticking with Norton Systemworks 2003
