- Make sure you have automatic updating turned on. This feature ensures that you have the latest security improvements from Microsoft installed on your computer. If you’re using other antivirus software, make sure that it is up to date with the latest malware definitions.
- Manually update your security software, reboot your computer, and run a full scan.
