I have Xp Pro, I never ever get viruses or spyware or hackers woot I dont know how I do it
1.Spyware-Ad-aware, Spybot Search and Destroy
2.Viruses-Either Norton Anti Virus 2005, Or Mcafee Anti-Virus
4.Browser- No browser is safer than Fire fox www.getfirefox.com
5.spam-Mcafee Spam Killer
I dont know I just use all that stuff, I make sure that its updated and I run them at least once a week, And I never get viruses or spyware etc....
Another good way to stay protected is to make sure that all of youre spyware and virus programs are up to date
And I do all of the windows updates for my computer
