We have received some reports of people either getting a Trojan Horse message or Payback suddenly 'disappearing' from their computer.

This is a false positive report and we've informed Microsoft so they can remove this from their threat database.

We can confirm that there is no virus or malware threat.

Microsoft have now removed this from their malware definitions so this problem should not happen in the future.

Go to Windows Security

Go to Windows Security. You can access this either by the Windows Control Panel, or by:

Clicking the little up arrow (^) at the bottom right of your desktop

Then click the Shield icon to go to Windows Security.

Change Settings for Virus and threat protection

Click Virus and threat protection in the Window Security screen.

Restore Payback

Select 'Restore' whereever an affected item has Paybackie in the name.

As soon as you do this, Payback will reappear.


Note that if there are any other quarantined items, DO NOT restore them!


  • You may also like to move to Cloudpay, where you are not at the mercy of third party products and issues such as this do not happen. Please let us know if you would like to do that.
  • You may have to re-install Payback. If you do this, the threat screen may appear again. Select 'Allow' if it does.
