Running Spybot and Windows Defender – Windows 10 (Error 577)

February 4th, 2016

User of Windows 10 may have noticed that Windows Defender will stop running in Windows 10 when Spybot is installed.

Windows will disable this program if it detects another antivirus program on your PC in order to prevent conflict between the multiple antivirus programs installed.

The Free Edition of Spybot also falls into this category, because it contains antivirus components from the paid editions.

To fix this issue, please disable Spybot’s Security Center Service using the instructions below, as this will prevent Windows from detecting Spybot as an antivirus program.

  • Open Spybot by right clicking on the Spybot icon and click “Run as Administrator”.
  • Open Settings (Tick the checkbox next to “Advanced User Mode” if you do not see “Settings”)
  • In Settings, go to the System Services tab.
  • Here, click “Stop” beside the Security Center Service.

After disabling the service and rebooting your PC, Windows Defender should function correctly again when it is run.

However, the antivirus programs could now conflict and cause issues.

To avoid this with Spybot, please also disable Live Protection / Real-Time Protection in either Spybot or Windows Defender.

You can find instructions for disabling Spybot’s Live Protection here.
