My first compromised XP computer

Picked up an XP dinosaur tonight from a customer who currently does not want to upgrade and insists on using XP.  I am discovering why you really should ditch XP.  Currently not connecting to the internet.  Solved that, now doing my typical scan of the system and the amount of issues present is astonishing.  At this point, it is definitely a result of not upgrading.  I fixed this system 2 weeks ago and right now it is almost crippled with issues.   Tell your stubborn friends, please upgrade.  If not for yourself, for your local tech guy!
