Summary

Microsoft Defender Antivirus detects and removes this threat.

A trojan is a type of malware that can’t spread on its own. It relies on you to run them on your PC by mistake, or visit a hacked or malicious webpage.

They can steal your personal information, download more malware, or give a malicious hacker access to your PC.

Because of the way this threat works, it might be continuously detected.

To restore your PC, you might need to download and run Windows Defender Offline. See our advanced troubleshooting page for more help.
