More safety tips
Keep your Windows up-to-date and always install Microsoft security updates as soon as possible. The easiest way to do this is by configuring Windows to automatically install new security updates.
In addition, you should always have a current virus scanner installed on Windows computers. If you do not want to use a third-party virus scanner, you should at least use the Windows Defender provided by Microsoft with Windows.
