Windows Defender is an anti-virus and anti-malware program developed by Microsoft specifically for Windows-based computers. It was first released with Windows Vista, replaced with Microsoft Security Essentials in Windows 8, and integrated back into Windows 10 as Windows Defender Antivirus.
Windows Defender can be used to detect, quarantine, and remove malicious software on your system. It uses the same malware database as Microsoft Security Essentials, so it’s just as effective at detecting and eliminating viruses and other malicious programs.
The question of whether you should keep Windows Defender turned on is a personal one and depends on how much risk you’re willing to accept. Windows Defender is generally considered to be a good security measure for most users, as it is free and pre-installed with Windows. It can provide basic protection from malware, but it’s not as robust as commercial anti-virus programs.
If you are looking for complete protection from all sorts of threats on the internet, then you may want to consider upgrading to a third-party anti-virus solution. These anti-virus programs offer more in-depth scanning and protection than Windows Defender, as they are constantly updated to keep up with the latest threats.
However, if you are only looking for a basic level of protection and aren’t very tech-savvy, then Windows Defender can be a good option for you. It’s free and provides basic protection from viruses, malware, and other malicious software. It also has built-in features that make it easier to use, such as automatic scans and scheduled scans.
Ultimately, there is no wrong answer when it comes to whether or not you should keep Windows Defender turned on. It’s ultimately a personal decision based on your tolerance for risk and your knowledge of computer security. If you want extra protection, then you may want to invest in a third-party anti-virus solution, but if you are happy with the protection provided by Windows Defender, then there is no reason to turn it off.
