    Windows Defender Taskplaner Job "Windows Defender Scheduled Scan" Error 0x80508018


    Hello, I searched the complete Internet ;- , but I found no good answer: Why does the task ""C:\ProgramData\Microsoft\Windows Defender\Platform\4.18.2211.5-0\MpCmdRun.exe" Scan -ScheduleJob -ScanTrigger 55 always reports the error 0x80508018. The main problem is the undocumented option "Scantrigger 55". Without this option, the task works. If I change the option to "Scantrigger 50" the task works as well other values 21, 22 .. work as well, So the main question is : What does the undocumented option "Scantrigger 55" exactly do ?Regards Dietmar

    :)

    Windows Defender Released

    Microsoft has released the final version of its Windows Defender anti-spyware utility. Windows Defender is a product of the Microsoft acquisition of GIANT Software. Previously known as Windows AntiSpyware, after a two years beta period it's now available for Windows XP and Windows Server 2003 under the name Windows Defender. Windows Defender incorporates Real-Time Protection to monitor systems for spyware activity, automated spyware removal with scheduled scans, full integration with Internet Explorer 7.0 and automatic spyware definition updates from Microsoft. Windows Defender is available freely to all customers running a genuine copy of Windows. Microsoft has also announced that customers will each be allowed to report two support incidents for free with Windows XP and Windows Server 2003.

    Hi Ian,

    Thanks for posting your query on Microsoft Community.

    This issue might occur if you have set any task scheduler for Windows Defender.

    I suggest you to delete the task for Windows defender and check if it helps.

    Follow the below steps:


    • Search and open Schedule tasks.

    • In the left-hand menu, open the Task Scheduler Library, then select
      Microsoft >Windows >Windows Defender.

    • Double-click Windows Defender Scheduled Scan.

    • Select the Triggers panel, then select Delete.

    Hope it helps, reply to us with the status of your issue. We will be happy to assist you.
