So me and my friend were having a discussion another day, he's an computer engineer and he says that buying an antivirus program is foolish because Windows Defender has really caught up with premium antivirus software, and is sufficient enough for users. What is your opinion guys? Do you think I should invest in a paid antivirus?

Defender is sufficient if you use Windows 8 or 10 otherwise forget it. Windows Defender for Windows 7 is nothing more than anti-spyware. For Windows 7 Microsoft advised using Microsoft Security Essentials but Microsoft has given up development and advise using a third party antivirus on Windows 7.

The comments of mikey11 and JohnC_21, taken together, explain the current state of affairs about as perfectly and succinctly as possible.

 

I haven't used a third-party antivirus on my Windows 10 machines since they became (or were purchased as) Windows 10 machines.

 

Microsoft didn't do anyone any favors by reusing the Windows Defender name when they greatly expanded its scope of function with the advent of Windows 8.  I believe the next major release of Windows 10 is going to see its name change to Windows Security Center or something similar.  For myself, I think the sooner they chuck the Defender name, which has led to endless confusion, the better [though the confusion will now always be part and parcel of the mix].

If you are using Windows 10, then I would recommend Windows Defender (Windows Antivirus). I explain why in this topic.
Also see my comments about Windows Defender (Windows Antivirus) in Choosing an Anti-Virus Program.

@ quietman7 -- Why mention Win10 only? Doesn't WinDef do a good job for Win7 & 8?

 

@ anyone who knows -- Does WinDef include a behavior blocker?

I will try to reply to the best of my knowledge.

 

Windows Defender on Windows versions lower than 8 it's NOT A COMPLETE AV program. That's because Windows Defender has become somewhat of a misnomer. On w7, for instance, the Windows Defender included was just an antimalware program. Nothing else and nothing more.

 

On Windows 8+ Windows Defender is a full-fledged (or almost full-fledged) AV package that can compete with most Free AVs out there and even with some paid ones. It does its job. It has a small performance footprint and it's really free (it won't nag or pester you with any popup messages saying you need to pay to get all the bells and whistles).

 

And I think Windows Defender (which has evolved a lot over the years), it has got a behaviour blocker (AKA "block at first sight"). I think it's enabled by default if leaving WD configuration options at default (real-time protection, cloud lookup and such).

Windows Defender in Windows 7/Vista is an anti-malware (anti-spyware) program intended to supplement your anti-virus program, not replace it. However, this version of Defender is weak, meaning it does not provide comprehensive protection and cannot prevent, detect and remove all threats at any given time. Although it uses the same name, Windows 10 Defender is not the same as Windows Defender in Windows 7/Vista since it integrates both anti-virus and anti-malware protection.

 

Windows Defender real-time protection in Windows 10 Anniversary Update includes behavior monitoring and heuristics to identify and block crypto-malware (ransomware) based on known suspicious and malicious activity.

In Windows 10, version 1607, we invested heavily in helping to protect against ransomware, and we continue that investment in version 1703 with updated behavior monitoring and always-on real-time protection.
Windows Defender Advanced Threat Protection

 

Windows Defender Antivirus in Windows 10 Fall Creators Update, Windows 10 Creators Update and Windows 10 Spring Creators Update continues with improvements and additional security features to protect against ransomware. Windows Defender Exploit Guard has four components of new intrusion prevention capabilities designed to lock down a system against various attack vectors and block behaviors commonly used in malware attacks before any damage can be done. Windows Defender EG is intended to replace Microsoft’s EMET which was confusing to novice users and allowed hackers to bypass because the mitigations were not durable and often caused operating system and application stability issues as explained here. Windows Defender Exploit Guard enhanced attack surface area reduction, extended support to Microsoft Office applications and now supports Windows Server as explained here.

Windows Defender System Guard is designed to protect and maintain the integrity of the system as it starts up; protect and maintain the integrity of the system after it’s running; and validate that system integrity has truly been maintained through local and remote attestation. Windows 10 Spring Creators Update includes platform security with Memory integrity in Core isolation (VBS) by bringing a subset of VBS features to all editions of Windows to ensure users remain safe from sophisticated cyber attacks as explained here.

"Controlled Folder Access" Anti-Ransomware is a feature that allows you to protect files in certain folders to that they cannot be modified by unknown applications. This protects the files within these folders from being encrypted by a ransomware infection. In Windows 10 Spring Creators Update, Microsoft has added a dedicated Ransomware Protection section in the Windows Defender Security Center under the "Virus & threat protection" settings.
