I cannot install McAfee Internet Security 2010 because of Trend Micro 2006 personal Firewall conflict. Can some one please help with this problem. I've called the McAfee help desk with no resolve.
First download/install Revo uninstaller application on your computer from http://www.revouninstaller.com/ & then i hope you should be able to uninstall
Trend Micro 2006 personal Firewall using Revo uninstaller if you can't find it under usual Add/remove programs.
Disclaimer : Revo uninstaller is a 3rd Party tool, you download/instal this @ your own risk. However as far as i know this tool hasn't caused any harm to PC.
