Trojan:Win32/Wacatac

Detected by Microsoft Defender Antivirus

Aliases: No associated aliases

Summary

The Wacatac trojan enters a device or system by deceiving users into downloading and launching a malicious file that appears legitimate.

Microsoft Defender Antivirus automatically removes threats as they are detected. However, many infections can leave remnant files and system changes. Updating your antimalware definitions and running a full scan might help address these remnant artifacts.
