Hi,
It's likely that there are still malware files present. The malware removal
programs can't remove everything.
First try BHODemon from
http://www.definitivesolutions.com/bhodemon.htm to
disable legitimate and questionable Browser Helper Objects. If a BHO or
add-on isn't causing the problem, you should download HijackThis and submit
a log to one of these sites for analysis.
Look for the proper forum and an "Important- Read This First" message so
that you follow proper procedure.

Or...
A legitimate program running in the background may be causing this. Disable
(for diagnostic purposes) programs such as pop-up blockers, security,
toolbars and other add-ons for IE, anti-virus, etc. Take a look at any
program that might be interfering with IE. You may have to reinstall, or not
reinstall, a program.
