Uninstalling Trend Micro’s PC-cillin Internet Security suite without a password

Submitted by on Thursday, 19 July 200719 Comments

Go to your registry.

Delete this key: HKLM\software\trendmicro\pc-cillin\system

BE CAREFUL AS YOU’RE DEALING WITH THE REGISTRY. I HIGHLY SUGGEST YOU EXPORT THAT KEY FIRST PRIOR TO DELETING.

Go to your control panel, add/remove programs, click on the Trend Micro PC-cillin Internet Security “Remove” and be done with it.

Toodles.

    Thanks for the information about the registry, it worked a treat,
    my client was unable to remember there password and this sort of thing makes it harder for technicians to repair there computers,
    So its sites like this that help technicians out a lot
    And thanks again
