In "Start Up" what are the systems that need to run and "don't" need to run

all you really need is a firewall and a anti virus application some developers offer suits which include it all together but to disable pograms that keep poping up upon start up go to start, run, then type" msconfig", click run, go the the start up tab, and check all the programs that do or dont want to start up.
Spyware and adware will get by almost every removal tool I ever used until I got Zone Alarm and now that is the only spyware program and virus program I endorse anymore! No I do not work for or own stock in Zone Alarm, but I probably should! It is the best I've used yet. When you browser freezes, this is a dead giveaway you haven't flushed them out yet!
