The developers are based in Romania and they have made a name for themselves by releasing light-weight and really modern-looking software. Let’s see what they have in the newest version of Bitdefender.

Test Results

Antivirus protection

Bitdefender uses the same malware detection techniques for all its Windows products. Bitdefender Antivirus Plus was tested by Reviewed by Pro researchers.

Firstly, we carried out a test using different samples of malware[2]. To our surprise, Bitdefender wasn’t that good at first – it hardly removed any viruses at all from the first full scan. However, results got a lot better after a restart of the system. After carrying out a full scan for the second time, about 80% of the malware and viruses have been removed. Even though it took a lot of time, we can say that Bitdefender is quite effective, but you will have to have patience.

Another test we carried out is installing malware and spyware on a Windows 10 system with Bitdefender Antivirus Plus already installed. The results looked good at first, as about 50% of the malware has been detected, blocked and quarantined. However, about 20% of the malicious software went through and infected the new PC. There’s another 30% of the malware that seemed to be blocked but left some leftovers in the registry and a few icons on the desktop.

In addition, Bitdefender Antivirus system was tested by the independent AV-TEST testing lab. According to AV-TEST test conducted in March – April 2018 results,[3] Bitdefender detected 100% of zero-day malware attacks, including web and e-mail threats and 100% of widespread and prevalent malware discovered in the last month. 

All in one, Bitdefender Antivirus demonstrates an excellent antivirus protection.

Bitdefender successfully identified and blocked 100% of the sites that were using phishing methods.

Now another important feature is the anti-phishing system[4]. We have to admit that Bitdefender Antivirus Plus did quite well on that, successfully identifying and blocking 100% of the sites that were using phishing methods. That’s a very rate for any prestigious anti-virus program.

Additional features

Bitdefender Antivirus Plus combines security, performance and privacy features. The package includes Complete Data Protection that works against various kinds of threats such as viruses, worms, Trojans, zero-day exploits, rootkits and spyware; Advanced Threat Defense, Multi-Layer Ransomware Protection, Anti-Phishing, Anti-fraud and Rescue Mode.

When it comes to Performance features that helps to increase device’s performance, speed, increase it’s battery life and more. Bitdefender Antivirus Plus includes Bitdefender Autopilot, Bitdefender Photon, Global Protective Network, Game, Movie and Work Modes and Battery Mode.

Finally, Privacy features include Bitdefender VPN, Safe Online Banking, File Shredder, Social Network Protection, File Shredder, Password manager and Vulnerability Assessment.

System-performance impact

We have measured the percentage of the operational memory that has been used by Bitdefender Antivirus Plus when a full scan was carried out. The results were pretty good – the anti-virus software took only 6% of the system’s resources. The only thing that caught our attention is that Bitdefender slows down the start-up of the system a bit – by approximately 20 seconds. However, it could be clearly stated that it is one of the most light-weight applications currently on the market because it almost takes no resources when Bitdefender just runs in the background.

In addition, according to AV-TEST, Bitdefender Antivirus Plus does not have a noticeable impact on system-performance and slow downs the system when launching popular websites or using commonly-used applications not more than the industry average.

User interface

Talking about the previous versions, Bitdefender is known to have a modern user interface[5] with nice colour schemes. If you have used a previous version of this software, then you will notice some differences. However, the new look is quite modern too and it is surely easy to use.

When using Bitdefender, sometimes it is not convenient to move from one feature to another, as you can get lost quite easily. That means the guys at Bitdefender could work on their navigation more – it could have been easier to have a menu on the left and then nobody would get lost in the user interface looking for a feature.

Customer Support

Of course, all of the antivirus software has a weak link to its chain and Bitdefender Antivirus Plus is no exception. There are some issues with the technical support part of it, which you may not like. Firstly, even though there is a button on the application that would let you contact the technical team, you will only get a form to fill in and you will not know when they should contact you. There are no time frames and no promises.

Of course, you can also try to reach them by email, but that might be just the same difficult case like reaching them by the built-in form. You will have to send your license key to prove that you are a customer with a legal version of the software.

If you get infected while using Bitdefender Antivirus Plus, you will need to pay an extra fee of 99$ for their technical team to remove the virus for you. However, some of the other big names in the market can offer you this service totally for free, so this fact doesn’t add an advantage to Bitdefender Plus technical support team.

There is one good thing about the support – they have a pretty huge database of frequently asked questions, documentation and various tutorials that you can use to identify the problem you are facing. However, it still doesn’t hide the fact that Bitdefender customer service avoids talking to their customers.

The final verdict

As you can see, the new Bitdefender Antivirus Plus has improved compared to its older versions. You can actually feel that these guys were working a lot on the resource usage – it is really one of the lightest programs on the market, so if you have a computer that gets slow very easily, Bitdefender Antivirus Plus might be a perfect choice. All in all, Bitdefender Antivirus Plus is a great anti-virus program with excellent antivirus detection rates and great set of privacy and security features.
