Antivir premium 9 re enables a Disabled Job

Hey guys,
I have a problem with the Scheduler in AntiVir Premium 9.I have a weekly scan that I implement. But this week I did not want to run it so I unchecked it as an option. But when the time came for the scan to run it actually ran even though I unchecked it. When I check it has been rechecked as an option. How do I fix this?
