Double-Protection Tips: Use Antimalware Software and Backup Together

Windows Defender is a built-in security tool in Windows 11/10/8.1/7 that helps protect your computer from malware. It does this by scanning your computer for threats and blocking them if they are found. Windows Defender can also help remove malware that is already on your computer.

What's more, to keep your computer running safely, you can also schedule scans, or scan your computer manually at any time.

Nonetheless, Windows Defender is not perfect and far from enough to fully detect all threats. However, it is a good first step in protecting your computer from malware. If we compare Windows Defender to a brave soldier defending against outsider intrusions, EaseUS Todo Backup is the warrior who saves the injured people from the war.

It's significant and essential to have both Windows Defender and Windows backup enabled on your computer:

  1. 1. Windows Defender can help scan for and remove malware, while Windows Backup can help restore your data if it is lost or corrupted.
  2. 2. In case Windows Defender fails to resist virus infection, the data backup can be the last hope of full recovery from the virus damage.
