Protecting your data from viruses, malware, spyware, and ransomware is crucial from external attacks.  Microsoft Windows version 7, 8, or 10 comes with a built in anti-spyware and anti-malware protection called Defender.  But, is it good enough to keep your sensitive data safe or do you need to install and purchase paid antivirus? To solve this question, we are doing a breakdown of the features of Windows Defender vs Paid Antivirus software programs.  Is Defender good enough not to purchase paid virus software?

What is Windows Defender?

Windows Defender is an anti-spyware and anti-malware protection installed onto the windows operating system.  Windows Defender can be used on Windows 7, 8, or 10.  Windows Defender is a good place to start your security preparations, but it’s important to keep in mind both the advantages and disadvantages of the software, so that you can make the correct decisions as time goes on.

  • Its free
  • Protects against Malware and Spyware
  • Most powerful protection software Microsoft has released
  • Frequent updates


  • Scan speed is slow

  • Limited functionality
  • No ransomware protection

Paid virus software

Reputable paid software will protect against all threats like Viruses, Malware, Spyware, Phishers, Key logger, and Ransomware.  Paid software will have more configurations and reporting to help tune your experience.  It also will have a faster engine that does not impede in the performance of the computer.


There is just no comparison using Defender compared to using a good paid virus protection.  I see hundreds of computers a month and it is alarming the users that have either never thought of installing a good paid virus software or letting the subscription expire thus Defender is automatically running and giving the user at least some protection.  Personally I would never use Defender as a solution but until I can get to every computer Defender is there protecting what it can.
