There are a number of ways to interpret your question. I will try to
answer all the possible permutations.
First: If the pop-up ads are coming from a free host (Tripod,
Angelfire, Geocities, etc), depending on the method implemented, it is
unlikely you will be able to avoid these advertisements from being
displayed to the end user without them installing additional software.
That is to say, if your web page is hosted on one of these services,
then a) you will most likely be violating their terms of service and
b) it may be impossible to remove the ads depending on their method of
implementing. As slicksingh2k-ga mentions,
http://www.cexx.org/diepop.htm will provide you information on
eliminating popups using these services (but is not an exhaustive
source for the reasons previously mentioned). Please see
recommendations at end of answer.
Second: If you are trying to allow users to go to your site and have
popup ads blocked for all subsequent sites, this is not possible
without the user installing additional software. Browser settings
usually require that they agree to this installation, or download the
software seperately and install it. Alternatively, if you are trying
to clean the user's machine of spyware, there is no automatic method.
Third: Depending on the choice of browser, these advertisements may
be automatically blocked based on user settings.
If you are using one of the free services, I would like to mention as
other researchers already have that there are a number of commercial
website hosting services that do not include popup advertisement
services. In addition, the company that provides your Internet
service MAY provide free, non-popup-ad web space. Contact them for
