Pop-up ads

How can you prevent them?

[webknowledgeskr]

I have a relatively popular site, and it has come to my attention that visitors are running into pop-up ads.
My question is, is there anything I can do server-side oor on the firewall to block these pop-ups? They are unwanted and are interfering with business. My site is running on IIS.

Please help.

If you aren't running pop up advertisments on your site, chances are your visitors have picked up some adware at some point while surfing the web.

As far as I know, there isn't anything you can do to prevent the pop ups from coming up when your site is visited because these popups are not originating from your site. The user must remove the adware from their own system.

Thanks for the info. I thought the major sites like Yahoo, and Google had figured out a way to deal with the issue server side.

You may have thought this but when I visit Google and other SEs I get popup ads (I know I probibally should clean my system). They try to prevent ads with their toolbars. I also heard somewhere XP SP2 is "supposed" to stop popups.

The popup ads generated by spyware and scumware on your system won't be blocked by any popup-blocking toolbars, because they are not generated by Internet Explorer, but rather by the scumware program itself. If you are getting popups on sites such as Google, you know you've been infected by something, and it is highly recommended to get the computer offline, and clean up with tools such as Adaware or Spybot Search and Destroy.

The scumware may just be serving up ads, but it may also hide a myriad of other problems with your system, making it unstable and insecure. You wouldn't want it to be sending out your online banking info to a remote server, or sending a few million spam mails in the background, would you?
