Windows10 Trojan detected Installation impossible

[aandrei]

Hi Dan,

I recently updated to from Windows7 to Windows10. I absolutely can not install/run the varranger.
I eved disabled UAC (that I should NOT do!) and still I can not run the program:
see what I get:
Threat found - action needed Severe
Threat: Trojan:Win32/Wacatac.C!ml
.......................................................
Details: this program is dangerous and executes commands from an attacker.
File: C:\Program Files\vArranger2\vArranger2.exe

More than that, Windows announce that the certificate for the program vas explicitly revoked by its issuer.
Same problem with vArrangerSynth.exe (revoked certificate).

Now, the program is invisible (quarantined).

What you suggest that I should do?

Hi aandrei,

I had the very same problem recently after updating my old laptop from Win7 to Win10 but I could release the .exe from quarantine and tell WIndows to leave it in peace in the future. It was not difficult but I cannot remember what I exactly did. Since then it works fine. Don´t be desperate, you will find the solution.

I installed and run the program. Now, Windows defender says: Active threats are running on your device ...Trojan:Win32/Bitrep.C

What is going on, Dan?

Uninstall the antivirus.

We also try to improve this a bit in new versions, and regularly submit false positives detections to antivirus vendors, but they finally decide...
