a better one than XP contains, zonealarm (do this first)

lots of this stuff is just normal traffic, and the
firewall doing it's job, no need to get notified.
get adaware download it update it, then scan your machine.
get cwshredder, do the same download update scan, get
spywareblaster, this will stop some of these
hijacker/helper programs from installing.
