I bought a laptop from a coworker of mine here recently. Got a heck of a deal. Too good to be true deal if you know what im saying. Anyways, i acquired it and in the midst of our transaction he states to make sure im using a firewall if i get on the wireless network cuz apparently the guy who got the laptop can track my activity. He said this with a smile, so i dont know if he's being serious or what. Now im about as noob as a noob can get. So bare with me. My question is if i do a complete system restore to factory settings before i install any other programs would that delete any programs that were installed on the system to prevent any activity from occuring? Also i included a screen shot from my computer folder, whats up with all the $uninstall$ folders? Im running xp pro right now but i may upgrade to vista later this week also what programs do i need to get, right now ive got AVG and of course spybot, adaware, spyware blaster...what are some good firewalls?
