Inet delivey sys??

I had (or possibly still have) a problem with popup adds. I am constantly connected to the net via cable, but the adds would popup if i was on the net (using mie) or not. Always 2 windows with random adds for this and that. I'd close them out and thats all, within a few hours they would pop back up.
After running HJT, i found that a porggy called "intdel" and "inetdel_2" were starting up on my computer from a file in my program files folder. I had not put them there and they were both applications. I have removed them both and fixed the line in HJT it was reffering to for the apps to start up.
I had noticed at the bottom of one of the web page popups was a "reffered by inet traffic-2" line. this must have been causing these adds from just popin up for no reason whatsoeven. Does anyone have any other info on this?
Thanks in advance, i did a search for inet here on your forums and returned no hits like i described.
