THE SOLUTION TO ADS
go to downloads.com and find and download spywareblaster, and spybot (no spybot isnt the cause of the problems, that person lied. its spyware or adware thats the cause. spybot is the cure.) and install the programs, run em, update em, use spybot's scan to eliminate adware/spyware, and use spywareblaster's enormous range of scripts to immunize yourself from the adware/spyware (and, a couple virii, as ive noticed... worms to be specific).
goto the start menu, goto run, type in command, use the dos prompt to get to the directory c:/windows then type in "edit hosts" with no quotes, then press enter, then type in:
"127.0.0.1 localhost"
then on the following lines, as many as you want, you can do something like
"127.0.0.1 ads.track.net"
or
"127.0.0.1 track.net"
track.net is an ad site. you can put whatever site in the place of track.net. whatever you put, will turn the banners from that host, into "this page cannot be displayed" in microsoft's IE.
also, those people who mentioned the google toolbar are right, it does stop all popup windows that are automatically brought up. i use it.
if there is anything i missed, be my guest, tell me what i missed. yes i am completely aware of ad-aware, (accidental pun) but spybot is the better alternative.
