Is Bitdefender Good?

Well, let me make it easy for you. You expect solid protection against virus attacks, less intrusive, should not degrade computer's performance, and not to forget, at a reasonable price. That makes a perfect choice!

Is Bitdefender good? Is it worth a try or good enough to fulfill all those requirements? In case you are in no hurry, you can read our detailed Bitdefender Total Security review.

So, I am going to dig deep into Bitdefender's performance and other factors to find out the truth about whether Bitdefender is good or not.

How effective is Bitdefender Virus Protection?

I don't believe in the claims made by companies that are nothing but marketing gimmicks. So, I will just take into consideration the results of independent Antivirus testing labs. Also, I will consider a lot of user reviews to reach my judgement.

VBSpam+ Award

In the latest Virus Bulletin's VBSpam test reports, Bitdefender scored 99.98, earning the VBSpam+ award for its high spam catch rate and superior detection.

 "Bitdefender has been participating in Virus Bulletin's VBSpam testing program since its outset in 2009 and has achieved a pass in every published test it has taken part in," said Ionuț Răileanu (VBSpam Test Lead - Virus Bulletin).

AV-Test and AV-Comparatives

AV-Test Institute rates antivirus programs on protection, performance, and usability, assigning up to six points in each category. Bitdefender earned 18 out of 18 in this three-part test. AV-Comparatives performs a wide variety of tests, four of which I follow closely. Bitdefender rated Advanced+, the highest rating, in all four. Bitdefender also bagged the Product of the Year Award for 2022.

So, we can conclude that it is pretty effective and something we can rely upon.

Moving on to next factors.

Does Bitdefender Slow down Computer?

does Bitdefender slow computer

It is said that an antivirus program slows down computer speed by 10 - 15%, and that is not completely false. Many Antivirus solutions use a huge amount of resources, leaving a little for other computing operations. However, with time and iterations, they have focused on low-impact performance.

Even our customers, especially gamers, prefer Bitdefender over any other solution. They are certainly the ones not ready to trade off the Gaming score for security.

Does Bitdefender slow down Internet surfing speed?

Test also includes operations like launching a website and downloading a file from the Internet. As Bitdefender is configured to scan files only after the download, there was no extra load.

While launching a website, however, Bitdefender had a load point (1), which is justified considering real-time scanning and Phishing website detection. Still, only 1 point is considered as lowest when compared to others.

You can configure Bitdefender to scan fewer elements on web pages. We have noticed that using SSL scanning can slow down page loading speed at times.

What Makes Bitdefender Different?

Just Install and forget it. Dead accurate and silent than ever.

Bitdefender's AutoPilot is the most innovative of its features because it takes the guesswork out of protection by covering the firewall, antivirus and privacy settings, and automatic updates. All you need to do is set up a user profile, and Total Security does the rest.

You will hardly notice that it's there.

Bitdefender Photon ensures that no computing power is wasted on constantly scanning trusted applications. Bitdefender developed Photon so that users can gain the benefit of maximum security while enjoying a great user experience and optimized computer performance.

Includes Ransomware Protection.

Before anyone else, Bitdefender introduced Ransomware protection module in their 2016 version. It monitors important files and blocks any application trying to alter/change it. Though it is capable of analyzing behavior and blocking applications like CryptoLocker, WinLocker or MBR, you must read these 11 things to protect yourself against ransomware.

Additional features.

Helpful and useful features available in Bitdefender Internet Security, Bitdefender Total Security, and Family Pack versions include Parental Controls, Firewall, File Shredder, Secure Browser for online transactions, Webcam Protection, and Microphone Monitor.

What's Good about Bitdefender?

  • Low Performance Impact
    It doesn't slow down computers and is designed to not interrupt while gaming or watching movies.

  • Ransomware Protection
    Freshly introduced protection module as a shield against modern threats.

  • 100% Zero-Day Malware Test
    Bitdefender detected almost all of AV-Test's 363 samples of zero-day malware, with the industry average being 99.4 percent.

  • Top Notch Fraud Fighter
    According to PC Mag review, Bitdefender did an impressive job of detecting freshly submitted phishing URLs outperforming its competitors.

What's Bad about Bitdefender?

  • Slow Full System Scan
    The first scan took 35% longer for a full system scan in our tests compared with others. This should not matter as long as you are scheduling it at night or when not working. If that's not the case, AutoPilot will detect idle machine and utilize that time for scanning.
  • Huge Installer File
    It's almost half a gigabyte of space on a Hard Disk. In an era of having storage in terms of Terabytes, this shouldn't matter, right?
  • Auto-Renewal
    When you buy the product from the official website, by default, the auto-renewal is active. The cart design makes it impossible for a new customer to identify and disable it. Hence, you have to be careful!

  1. I run Bitdefender Total Security and have never had a problem with the software or its performance. The computer boots quickly. When I first changed to the current version It did take me a long time to find the Update (installs the latest potential threat ID’s), searching the programme top to bottom without success. I then found it, not in the programme itself, but elsewhere on the computer, easy to access, just click and there it is. Maybe I could have paid more attention to the instructions?
    However, as said, Bitdefender is, in my opinion, very good and puts no obvious load on the computer (a desktop), keeping itself up to date (once per hour). I, as an ordinary user, have no complaints at all.

  2. BitDefender is the safest to use as it provides all the latest criteria to catch malware and it does not disturb others apps. This is the Best Value for Money Antivirus.

  3. Does it see whether the download is safe or not? and is it free?
    Will it really slow my computer i got icore 5 4gb ram and i am using a laptop

  4. I am using also Bitdefender. I install it because my all web browsers are opening new tab but all the time. I was scanning and cleaning my mac book pro with Bitdefender several times, but still the browsers but themselves are opening new tabs. Can you please help me what can I do with it? How can I stop it? P.S – I am new mac user. Thanks in advance!

  5. Adequate protection is provided. The down side is that internet connection is slow to impossible & would not allow the printing of pages from the internet or pages from an email. Needed to completely uninstall in order to bring my MacBook pro back up to speed.

  6. Bitdefender is a scam, I bought a 3 year for 3 computer subscription, after one month I got a notice that my subscription has expired. I called their help line, they verified that I bought a 3 year subscription, but now they want to charge me a maintenance fee to reload it on my computer. I reversed the charges on my credit card and will never to business with them again.
