Installing sp2 behind a router

[imported_mson]

If I install XP sp2 via windows update behind a router will that protect me from the worms that are out there?

It'll protect you from hackers if you use the routers firewall and also Windows XP SP2 firewall. Getting all the latest MS updates and possibly a anti-virus package that can protect against worms should help to keep you safe.
