Hi,
This is usually caused by another program- often malware. Start with
BHODemon from
http://www.definitivesolutions.com/bhodemon.htm Your problem
may simply be a bad BHO.
Then download and run CWShredder, Ad-aware, Spybot (in that order.)
See:
http://mvps.org/winhelp2002/unwanted.htm
Also note the security tips and other important information on that page.

If unsuccessful with those programs, you may have to post a HijackThis log
for analysis. Start at
http://forum.aumha.org/viewtopic.php?t=4075 Then go to
http://www.aumha.org/a/quickfix.htm work through the preliminary cleaning
steps and post a HijackThis log to the forum at
http://forum.aumha.org/viewforum.php?f=30
Or...
A legitimate program running in the background may be causing this. Disable
(for diagnostic purposes) programs such as pop-up blockers, security,
anti-virus, etc. You may have to reinstall, or not reinstall, a program.
