Step 3. Select Full scan and click on Scan now. When the Behavior:Win32/Rugmigen.B malware is detected, it will immediately remove it from the system.

Way 2. Manually Remove the Behavior:Win32/Rugmigen.B Virus

According to user reports from the Microsoft forum, the Behavior:Win32/Rugmigen.B mainly occurs after installing the latest update, KB5053606. If this scenario also applies to you, follow the guide below to uninstall it and manually delete the virus.

Step 1. Press the Win + I keys to open the Settings app, and then select Update & Security > View update history.

Step 2. Click on Uninstall updates, and then right-click the most recent update and select Uninstall. Then follow the on-screen prompts to complete the uninstallation.
