Windows Defender Glitche

Sometimes (once in a blue moon 0-) Windows Defender suddenly blocks MultiMaps setup file.

We are absolutely sure this is an erroneous Windows Defender behavior, so called “false positive”:

All users who faced this issue use Windows Defender as antivirus program. Other antiviruses don’t detect any threat.

  • We checked MultiMaps setup files with the most powerful anti-virus online services: VirusTotal and Kaspersky VirusDesk. Both services did not detect any threats. You can do it as well (see step 6 below) when you have some doubts.
  • Also we checked setup files with Windows Defender’s own online service ( And it did not find threats as well!
  • After download and install MultiMaps version that Windows Defender considers infected, we checked one by one all the files in the installation directory – with the same Windows Defender. He did not find any threat in either of them. Here is an interesting result – none of the files Windows Defender detects as infected, but.. finds a trojan in the setup file of which this one consists…

So, if you want to use MultiMaps add-in, but Windows Defender does not allow you to download and install it, you can:

  1. Open Windows Defender: click on the Settings icon in Windows system tray and go to Defender Security Center or find Windows Defender Security Center in the Windows Start menu.
  2. Click the “Virus & threat protection” icon.
  3. Click the “Virus & threat protection settings” link .
  4. Turn out the “Real-time protection”.
  5. Download MultiMaps setup file.
  6. At this step you can check the setup file as described above – via online services VirusTotal and Kaspersky VirusDesk.
  7. Or you can immediately install MultiMaps and turn on real-time protection disabled on the 4th step.
  8. To prevent Windows Defender from blocking MultiMaps setup file in the future, put this file in Windows Defender Exclusions. To do this: in the same window as the real-time protection, scroll down to “Exclusions” and click the link “Add or remove exclusions”. In the next window click “Add an exclusion”, then “Exlude a file” and then browse to and choose the downloaded MultiMaps setup file.

Good luck!
