Introdution to system administration in Window Xp

I disable autorun feature in my PC and created a Limited user account, so that I'll be protected from malwares and virus that get inside my PC thru a USB device. I also install Avira PersonalAntivirus, which solve(coz' AVG don't work)my virus problem in the past.


Could somebody please give me tip on how to use sys admin account to protect my PC? thank you in advance!!

Hello,

What do you mean by use "system administration"? Don't you already have an admin account?
