Avast vs AVG vs Windows Defender – Which Antivirus Is Better?


You can’t risk leaving your computer unprotected while surfing the internet. You’ll get infected with all kinds of viruses and malware, and in worst cases, hackers could steal your identity, your money from your bank account, and all you’ve built in your life can collapse in a moment, because you didn’t install an antivirus program. We will compare three of the best software and you’ll decide which one is best for you.

Avast Free Antivirus 2015

Since it’s a free antivirus, it offers only basic protection against viruses and spyware. It monitors your browser activity and informs you if you have weak passwords or mediocre settings. You’ll get a Dropbox account with 2GB of free storage and for your Android mobile you’ll get a free separate application, plus anti-theft provision.

In a performance test, Avast scanned around 18,000 files (50GB of files) in 5 minutes and a half (55.4 files/second), but the re-scanning was quicker and overall, the final score was 4.0 out of 6.0 because it has a 4-second delay.

Its interface is simple and in the left-hand side is a bunch of menu options. You have the option to adjust settings, get information about recent threats, etc. In the Usability tests, Avast scored 5.5 out of 6.0 because it gave four false positives in two months after it was installed.

AVG Free Antivirus 2015

Besides the free protection against viruses and spywares, AVG offers add-ons for many browsers, to provide safer searching. The interface is also simple, the fonts are bold and after performing a scan, a pop-up will appear, informing you when it’s done. In the AVG-Test, it gave only three false detections, which makes AVG one of the most reliable antivirus programs, since the group average is seven false detections.

The interface will somehow encourage you to upgrade to the Pro version, in order to get additional features. The program scanned around 240,000 files at a rate of 65.2 files/second, which is a weaker result compared to Avast.

Microsoft Windows Security Essentials (Windows Defender)

It can be downloaded for free from Microsoft’s website, and it provides Security Essentials (WSE) with Windows 7, while Windows 8 and 8.1 will receive the same function with Windows Defender. The antivirus detected 77% of established threats and found 55% of the zero-day attacks.

WSE scanned 50GB of files in over three and a half hours, resulting in a scan rate of 102.9 files/second, but at least it didn’t give any false positives.
