Honestly, it really depends on if you're connecting it to the net directly, through a Firewall, or through a VM, as well as what you're doing and if you have an adblocker.
As long as you have a decent Firewall, adblocker, and are using common sense, you should be fine.
If you're extra paranoid, you can still set up an antivirus, since some still support XP
