Firstly you should clean your computer of adware and similar pains:
Get Ad-Aware 6.0, Build 181 or later, here:
http://www.lavasoftusa.com/support/download/. Update and run this regularly
to get rid of most "spyware/hijackware" on your machine. If it has to fix
things, be sure to re-boot and rerun AdAware again and repeat this cycle
until you get a clean scan. The reason is that it may have to remove
things which are currently "in use" before it can then clean up others.
Another excellent program for this purpose is SpyBot Search and Destroy
available here:
http://security.kolla.de/ SpyBot Support Forum here:
http://www.net-integration.net/cgi-bin/forums/ikonboard.cgi. I recommend
using both normally. After fixing things with SpyBot S&D, be sure to
re-boot and rerun SpyBot again and repeat this cycle until you get a clean
"no red" scan. The reason is that SpyBot sometimes has to remove things
which are currently "in use" before it can then clean up others.
After this, people have reported that repairing or re-installing IE6 solved the problem.
Good luck.
