Ive used Trend Micro for about 6 years. I like it because it does the job, straightforward to configure, gives good control and updates are fast behind the problem.
Norton can be a bi*** to uninstall. TIP, download trial Trend Micro Internet Security and install without first having uninstalled Norton. It uninstalls Norton perfectly and without any user interaction.
Then if you want to uninstall TM, just click the uninstall. Clean system
