How to stop sheduled PC scan

I cant stop scheduled PC scan on SDP. I create schedule scan in web form http://SDPServer/SetUpWizard.do?forwardTo=netDefconfig but this was big mistake. It began scan my huge domain. I disable schedule scan in web form but schedule task don't stop. HOW TO STOP IT? Maybe in DB?
There is table Schedule with row. I manually set ADMIN_STATUS column to Disable.
4 WorkstationSchedule No Description Disable 106
5 WorkstationRediscovery No Description Disable 107

there is table Task_input where task schedule with schedule_id = 4
