Let’s get started!

Bitdefender vs Avast: Security

The primary reason for installing any antivirus software is to provide an extra layer of security. In this category, we check out how Bitdefender Antivirus Plus compares to Avast Free Antivirus in their ability to detect and stop the most frequent malware that preys on PCs and their users.

AV-Comparatives, an Austrian testing lab conducted evaluations on both antivirus software in 2016 from July to November. While Avast managed to block 99.6 percent of online threats, Bitdefender did even better and blocked 99.9 percent of threats online.

False positives are benign or harmless programs that an antivirus erroneously sees as malware. The lesser false positives an antivirus registers, the more credible it is.

While Avast registered 13 false positives, Bitdefender registered zero.

Another evaluation made by AV-TEST in 2016, a German lab saw its results agree with that of AV-Comparatives.  Avast and Bitdefender were put to the test on their ability to detect both known and unknown malware. Bitdefender had better scores on the test than Avast.

Bitdefender was tested for Windows 10, 8.1 and 7 and it stopped 100 percent of both known and unknown malware for all Windows except Windows 8.1 where it stopped 99.9 percent of known malware and 98.7 percent of unknown malware.

Avast, on the other hand, had fluctuating results on Windows 10, 8.1 and 7. Sometimes detecting and blocking all unknown malware and at other times blocking less than 98 percent. These varying results mean the software is not quite as stable as should be.

In the security comparison of Bitdefender vs Avast, Bitdefender comes out as a better option with zero false positives and much better malware detection.

Bitdefender vs Avast: Installation and Ease of Use

Installing both Bitdefender and Avast is relatively an easy process except that Avast tries to install Google’s Toolbar into your web browser, as well as change your default browser’s home page to the Google homepage.

Bitdefender users can navigate to the home screen where they can toggle on the Autopilot mode. This mode runs an auto scan from time to time on the files on your device.
