Summary
Windows Defender detects and removes this threat.
This threat is detected in a webpage that shows a fake security scanner. It falsely tells you that your PC is infected with viruses and that you need to install other software to disinfect it. The software it offers for install is usually a rogue security software, which doesn't clean your PC and instead tells you that you need to pay for more, nonexistent, cleaning.
See the Rogue security software page for more information.
Use the following free Microsoft software to detect and remove this threat:
- Microsoft Defender Antivirus for Windows 10 and Windows 8.1, or Microsoft Security Essentials for Windows 7 and Windows Vista
- Microsoft Safety Scanner
You should also run a full scan. A full scan might find other, hidden malware.
