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 aashish!!! That worked perfectly!!!
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
