Best free antivirus for Android in 2018

Best free antivirus for Android

Malware, adware, fake applications, scams: just some of the dangers that your Android device can find every time you install something new.

The answer is simple, at least in theory. Independent tests show that the best antivirus applications do a great job to keep you safe and regularly block 100% of test threats.

The problem lies in deciding which application to use, because although there are hundreds, many are very inaccurate, and some can be malicious.

AV Comparatives 2018 The Android security report gives an idea of ​​the scope of this problem. The company tested more than 200 applications and, although many had a good performance, 79 detected less than 30% of the same malware or regularly generated false alarms with popular clean files. That suggests that about 4 out of 10 of the antivirus products you'll find in the Play Store are so poor that AV Comparatives found them unsafe or even deceptive.

It is important to choose your security applications with extreme care, then. To help, this article will highlight five of Android's best and most trusted free antivirus applications, as evaluated by our own experience and the results of AV Comparatives and AV Test evaluations.

Put it all together and Avira Antivirus Security 2018 offers complete and versatile protection for a free application, although there are a couple of problems that can persuade you to update.

Bitdefender Antivirus Free

3. Bitdefender Antivirus Free

Detection of lightweight malware from a market leader

Precise antivirus engine

Blocks threats automatically, requires no configuration

Does not include real-time scanning / blocking of web pages

Bitdefender's Antivirus engine is one of the most accurate and reliable, and regularly tops the detection rate lists of independent testing labs.

Mobile Insight not only searches for known malware, but uses multiple scanning techniques to detect new threats and potential privacy risks in legitimate applications, and Norton Security and Antivirus uses this information to warn you about dangerous applications before they can cause problems.

The results are often impressive, with Norton detecting 100% of the sample threats in the recent AV Comparatives test of more than 200 Android security applications.

Norton Security and Antivirus also has what appears to be a robust set of anti-theft features, including the ability to block, erase or remotely locate a stolen device through a text message. However, check the fine print and you will see that they do not work on Android 4.03 or later.

The main limitation here is the lack of navigation protection. You can avoid dangerous websites to some extent by using Norton's secure search tool, but the full SafeWeb filter, the excellent Norton website reputation technology, is only available in the premium paid edition.
