Tcp/Ip problem

A while back my wife ran some spyware and virus checks. Did the normal thing removing said threats, re-booting, etc. After the computer restarted we got a message saying the tcp/ip wasn’t installed. Through all my efforts i haven’t been able to come up with a fix without spending money or buying a new OS. I’m running Windows XP sp2. if anyone has any way to fix this let me know. Thanks in advance.

I just did a quick Google search and came up with this

It may or may not help you, hopefully it does. In serious cases probably the easiest thing to do is back up any important data and reinstall XP from scratch, at least you’ll have a clean slate then. Spyware and/or viruses can do alot of damage.
