Keep your computer secure at home – Microsoft Support

Keeping your computer secure helps you avoid malware and direct hacking attempts designed to steal your personal information. Here are some ways you can help reduce your online risk when you use your computer at home.

Don’t use USBs or other external devices unless you own them To avoid infection by malware and viruses, ensure that all external devices either belong to you or come from a reliable source.

Stay away from pirated material Avoid streaming or downloading movies, music, books, or applications that do not come from trusted sources. They may contain malware.

Browse the web safely Avoid visiting sites that offer potentially illicit content. Many of these sites install malware on the fly or offer downloads that contain malware. Use a modern browser like Microsoft Edge , which can help block malicious websites and prevent malicious code from running on your computer.

Don’t open suspicious attachments or click unusual links in messages. They can appear in email, tweets, posts, online ads, messages, or attachments, and sometimes disguise themselves as known and trusted sources.

Tip: If you’re a Microsoft 365 Family or Personal subscriber, you get Microsoft Defender included with your subscription at no extra charge. It helps protect all your devices – Windows, Mac, Android, and iOS. For more information see Getting started with Microsoft Defender.

Use antivirus software and keep it current If you run Windows you have Windows Security or Windows Defender Security Center already installed on your device.

Keep all software up to date Make sure to turn on automatic updates in Windows Update to keep Windows, Microsoft Office, and other Microsoft applications up to date. Turn on automatic updates for non-Microsoft software as well, especially browsers, Adobe Acrobat Reader, and other apps you regularly use.
