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

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.

Why do I see “Internet protection: basic” in Spybot’s Start Center?

SDDisableProxyResultIf your Internet protection is set to ‘Basic’ the most likely reasons are that when the software was installed the default setting was ‘Disabled’ or when updates were installed the setting was changed automatically. This setting can also be changed by the user.

The ‘Proxy’ feature filters all Internet traffic thus it can reduce your browsing performance. While this provides maximum protection it can sometimes be annoying. We therefore issued an update to 2.1 and released a new Software installer (Spybot 2.1.20 SR 1). This update turns off the Proxy and so the Start Center to display “Internet protection: basic” instead of “full”.

If speed is not an issue and you want all data coming from the internet to be filtered, you can enable the proxy by opening the Start Centre selecting ‘Settings’ clicking the “Internet Protection” tab and ticking the box ‘Use Spybot proxy’.

Why are some of my favourite internet sites blocked?

In that case the immunization has to be undone. To do so run the Start Center and click on “Immunization“. On the navigation bar on the left you can “Undo immunization“.
Please note: Now the bad downloads will not be blocked any longer! You may have to restart your computer. Then try again to open your favourite pages. Do not forget to Immunize again after visiting that page.
