Windows Defender, the built-in security application on Windows 10 computers is far more advanced than any of the security applications present in Windows systems. This desktop app can run in the background ensuring the basic level of protection every windows 10 PCs need.
If you’ve used Windows 8, this Defender program won’t be new to you. But, when it reaches at Windows 10, Defender advanced to a level that its predecessor couldn’t reach – both in terms of real-time protection or while updating with new malware definitions.
Working in Background
The defender can automatically run in the background while you’re working on any programs. It’ll alert you once it detects any malicious activity or virus on your system. Probably, you may see a pop-up that says “Malware detected” or “Windows Defender is taking action to clean detected malware” and so on. You’ll know any of such errors by looking at your Windows Action Center on the bottom right of your taskbar.
Anytime you can check whether the virus definitions on Defender is outdated or not. For that, open your Defender program on check Update tab. If virus definitions are outdated, it’ll show up here. If it’s outdated, click “Update definitions” button on the screen. It’ll check the web for the latest spyware definitions and if found, it’ll get downloaded and installed on your PC.
In case of outdated virus definitions, you’ll also receive notifications about this through Action Center or via pop-ups from Defender program through system tray.
Once you find a virus infected item through Defender, you can either quarantine this item or allow it to run on your PC. You’ll get information on all these quarantined and allowed items through History tab on your Defender program. You can remove items located in quarantine anytime for your convenience.
It’s the time to move a little-advanced section – Windows Defender Settings. Here, you can turn Off the Real-time protection that disables your defender program in your PC. It can be enabled back at any time. An Automatic sample submission option allows Defender to send samples of suspicious files to Microsoft to aid malware detection. By default, this option will be turned on and if you want, you can turn it off.
And, a Cloud-based protection option is available here that enables Defender to send info to Microsoft about potential security threats. If you’ve enabled automatic sample submission option, it’d be great with this option.
If you want, you can add exclusions in Windows Defender making your PC more vulnerable to malware threats. You can exclude a particular file, a folder or a file type. If you exclude a virus infected file like this, Defender won’t treat that file as virus infected.
An option “Windows Defender Offline” will allow you to run a boot-time scan by using your recent virus definitions. Once the OS is loaded, it’s not possible to remove some virus programs from the PC. Here’s the importance of boot-time scan. It prevents virus programs to load in OS memory. So, Defender can easily remove such programs from PC.
Note: Sometimes with Windows Defender, you may accidentally delete some of the quarantined items. Using a professional file recovery program, it’s possible to get back such deleted items. But make sure that, the program won’t harmful for you after the recovery. Unless, you’ll really pay for that.
