MS Security Essentials kills Zorro as it is recognized as trojan

After the last virus definition update from Microsoft for the Security Essential package, zorro (v. 1.74) gets killed with the notification "severe threat", Trojan:Win32/Azden.A!cl.

Zorro Real running on a Windows 2008R2 Server.

Anyone similar issues?

First check if your PC is really infected. For this you can submit Zorro.exe to a scan service like https://www.virustotal.com.

If your PC is infected, please stop all work, reboot it from a clean media, and run a thorough virus check with a serious tool (not Security Essentials). Then download and install Zorro again.

- Update: We got similar reports from other users and have informed Microsoft of this incident.

Thanks for the fast reply.
I re-installed zorro several times and the zorro.exe was immediately eliminated by ms-sec-essentials. However, checking zorro.exe with Jottis Malware scanner, only one showed "something" (ClamAV, PUA.Win.Packer.Upx-48), all other engines reported nothing.

Repeated as suggested with virustotal. With one exception (Cylance, Webroot, W32.Malware.Gen) all others reported nothing.

We have now official confirmation from Microsoft that Zorro 1.74 contains no malware. Hopefully they fix their virus defender signatures soon.

Until then, I suppose you can enter exclusions in the security essentials configuration: https://docs.microsoft.com/de-de/windows...tection-history

Thanks a lot.
Yes, the exception for the folder was the first I did since it looked to me that this is an automatically generated false alarm. So much for heuristics.
That's why I checked back here.
