Q: Is Windows Defender Enough for Windows 10 in 2021? (Reddit)

"Thinking of sticking to Windows Defender because it is free. I do mild gaming and video editing but I use my rig also for work, mostly spreadsheets. Should I buy an antivirus?"

Q: Is Windows Security as Good as Antivirus?

"I can't find Windows Defender that I was reading about on my computer, but I do have Windows Security. Are these the same thing? Also, do I need third-party antivirus software or is Windows Security enough?"

When it comes to computer security, there are a lot of options out there. You can spend extra money on the best antivirus software, or you can use a free program like Windows Defender. From what we investigated, Windows Defender is generally far better than many free antivirus programs on the market, so it is a good option for home users who don't consider paid software. However, if you're looking for more comprehensive protection with fast scanning speed, advanced malware scanners and customer support, Windows Defender is honestly not good enough at this point.

Next, we will guide you with a full analysis of Windows Defender's features and abilities in virus protection, to help you make a decision with a clear mind. At last, no matter how many security programs you have on your PC, you must do regular backups to ensure that your data is safe in case of any disaster.

About Windows Defender: Features, Pros & Cons

Note: Windows Defender is also known as Microsoft Defender Antivirus and Windows Security.

Windows Defender is a program that helps protect your computer against pop-ups, slow performance, and security threats caused by malware, spyware and other unwanted software. It runs in the background and monitors your activities to make sure no malicious software is installed on your system. If it detects something suspicious, it will notify you and give you the option to remove the offending software.

Here are some of the key features of Windows Defender:

• Free yet powerful: As a free anti-malware solution, it's so far the best among all third-party free antivirus software on the market.
• Real-time protection: This means that Defender will scan your computer for malware constantly and block anything it finds.
• Automatic updates: Microsoft releases new virus definitions regularly, and Defender will download and install them automatically.
• Behavioral monitoring: This feature watches how programs behave and can detect malicious activity even if the program itself is not yet known to be malware.

As Microsoft's built-in antivirus program, Windows Defender has gotten better in recent years. The highlighted improvements we can benefit from the Windows Defender are mainly as follows:

• Reduced false positives with improved heuristics and machine learning models
• Enhanced detection of attacks that use PowerShell and exploit mitigations
• New capabilities to detect ransomware at the earliest stages of an attack
• Cloud-based protection that helps to guard against the latest threats

Does Windows Defender fall short in certain areas? let's find out some:

• Only runs on Windows. So, if you have Macs or Linux machines in your organization, you'll need to use a different solution for those devices.
• Doesn't protect against all types of threats. In particular, it's not very good at protecting against zero-day exploits and targeted attacks.
• Can be resource-intensive, which can slow down older computers.
• There have been some reports of false positives with Defender. E.g. Windows Defender-Security Warning.

Direct Answer to Windows Defender Good Enough or Not

Now that we've looked at an overall introduction of Windows Defender, let's answer the question: is Windows Defender good enough for basic security? The short answer is yes. Windows Defender offers a decent level of protection against most threats. And it's always improving, with new features and updates being released regularly.

But there are a few things to keep in mind. First, Windows Defender is not perfect. It can miss some threats, especially new and sophisticated ones. So it's important to supplement it with other security measures. Basically, third-party reliable antivirus software. The renowned ones are Avast, McAfee, Norton, Bitdefender and Avira.

Second, even if Windows Defender does its job well, it won't be able to protect you from everything. So it's important to be aware of the risks and take steps to protect yourself, such as using strong passwords and being careful about what you click on, especially the email attachments and some tech support scamming phone numbers.

Finally, remember that no security measure is 100% effective. There's always a chance that something could slip through the cracks. So it's important to have a backup plan in case something does happen. You must know that harmful virus generally corrupts your computer by encrypting your valuable files/folders with random codes, and no one can decrypt the infected files unless you pay the ransom.

Overall, Windows Defender is a good security program that offers a decent level of protection. But it's not perfect, and it's important to supplement it with other measures. And don't forget that no security measure is 100% effective. So always be prepared for the worst.

For Everyone: Build Your PC up with Virus-proof Backups

Windows Defender is a good security program and it is free. So it's not necessary to purchase any third-party antivirus software if you've already had Windows Defender turned on for real-time protection. However, you should never rely on only one form of protection, especially when it comes to your valuable computer data!

If you want to be as safe as possible, it's important to use multiple forms of protection, including a backup program. Here are some reasons why we focus on running backup software together with Windows Defender!

For one, even the best security programs can't protect against everything. There are always new threats being created that can slip past even the most up-to-date defenses.

Additionally, relying on only one form of protection leaves you vulnerable in the event of a software or hardware failure. If your only form of protection is a security program and it fails, then you have no other defense against losing all your data.

Backups provide an additional layer of protection by creating copies of your data that can be restored in the event that something goes wrong. This way, even if your primary form of protection fails, you still have a fallback that can help you recover your lost data.
