The Best Antivirus Apps for Android Smartphone in 2020

Best Android Antivirus Apps at a Glance

Today smartphones are more than just the means of communication: we store both personal information and bank account data in our smartphones. Mobile devices also allow us to solve many problems on the go, and this has made life much easier for people.

At the same time, confidential information, which is the primary target of cybercriminals, is becoming increasingly vulnerable. Moreover, devices and data can be lost and stolen. We risk losing them if we treat the issue of data protection carelessly.

Antivirus apps are as popular among users as the most popular social media apps. Also, malware and viruses can break the normal Android functionality, making the work with your smartphone inconvenient.

There are several security rules for owners of Android smartphones. First, do not download apps from the third-parties and do not follow suspicious links. Second, do not pay online if connected to public Wi-Fi, and do not forget to install antivirus on your phone.

The Android antivirus provides complete protection against mobile viruses and threats to personal data. The main goal of Bitdefender Mobile Security is to provide as many opportunities as possible to protect your Android device and essential information on it, not consuming a lot of system resources and battery.

Bitdefender is built on one of the most reliable and modern anti-malware engines (read the review here). During tests, this antivirus scored a perfect 100%. The software automatically scans all apps that are just installed or updated. However, there is no feature that would allow scheduling scans, and that’s a downside. The scan on demand is quite fast – it will take around 30 seconds. The antivirus is using cloud-based malware detection and doesn’t take a lot of resources.

Bitdefender Mobile security package will cost you $14.99/year. 14-day free trial is available.

Key features

  • Antivirus scan. The Bitdefender Malware Scanner automatically scans apps during installation to avoid installing malware. The antivirus runs in the cloud, so it is always up to date and protects your Android device from the latest threats and aggressive advertising.
  • The Application Lock feature shows a list of all applications installed in the system and allows you to select those that can be password-protected against unauthorized access. This way, only you and someone who knows the password can use these applications.
  • Bitdefender Web Security protects you in real-time when you visit websites by blocking malicious and phishing resources.
  • VPN. The service provides 200 MB of traffic per day for free. If you need more, please subscribe to the Bitdefender VPN.
  • Anti-theft includes a web-based remote control panel that allows you to send SMS commands, lock, locate, sound the siren and erase Android information from any device with Internet access, as well as to listen to your phone.

Download Avast

The mobile security application protects personal data with automatic virus scanning and notification of malicious URLs and blocks hackers’ actions using the built-in firewall. There is a basic free version, but the premium edition includes all the advanced options.

Avast antivirus offers pretty reliable protection, although lab tests are very inconsistent (read our full Avast Antivirus review). In some tests, Avast scores 100%, in others — only 5.5 out of 6. However, even the lower scores are not as bad – it has the award because of its low system impact. The app offers several modes: a real-time shield that protects the device from malware; the scan-on-demand; scheduled scans. The last option allows to schedule scanning for, say, 3 a.m. when you’re asleep, so you don’t have to deal with a laggy phone.

Prices for the paid option of Avast Mobile Security are as follows:

  • Monthly – $1.99/month
  • Yearly – $7.99/year

Key features

  • Antivirus scanner performs on-demand scans of installed applications and the contents of the SD card and scans in real-time when applications are first launched. It includes scheduled scanning, updating antivirus databases, deleting apps, deleting files, and sending false positives reports to the Avast lab.
  • Security advisor — privacy report. The app scans the system and detects all the potential privacy risks.
  • Application management shows lists of running applications and their size, CPU, and memory usage, as well as some threads and services.
  • Web Protection powered by the Avast WebRep cloud technology. The antivirus checks every URL you enter, alerting you if it is malicious. The new SiteCorrect feature detects the most common errors in URL typing and allows you to be redirected to the website you intended to visit.
  • Firewall (for rooted devices only) protects against hackers and network threats to your mobile device.
  • Wi-Fi Security component scans wireless network access points the device is connected to, and reports on their security level identify potential Wi-Fi vulnerabilities and offer solutions to address them.
  • Avast Anti-Theft: application masking, invisible mode, self-protection, battery power saver, notifications about SIM card changes, list of allowed SIM cards, remote control.

In general, this is quite a good Android antivirus solution from one of the most popular vendors. It works smoothly and provides enough protection for most users.

How to Choose the Top Antivirus?

Do we need antivirus for Android?

The biggest advantage of Android became one of its biggest problems. We talk about the openness of the operating system, which gives the opportunity not only to customize but also opens the way to create malware and viruses.

In most cases (like 99%), you don’t need to even think about an antivirus on your tablet/phone running on this operating system. Mass media has led regular people to believe that Android viruses are even more dangerous than the Windows ones, but that is far from the truth. At the same time, they do exist, which is why a robust modern-day antivirus will still have some work to do.

However, can Android phones be infected with viruses? Android devices do not receive traditional viruses like the computers do but can catch other malicious programs.

Android developers built several security features:

  • Rights for apps. You are able to control which application has access to different device functions such as a microphone, camera, location, telephone, and messages.
  • Software and security updates. Do not ignore the system updates — they include improved security.
  • Secure browsing. This feature allows you to block some suspicious and phishing websites you visit on your Chrome mobile browser.

Antivirus for Android will fix the security flaws in your operating system. Here are some features of typical antivirus:

  • Real-time antivirus protection.
  • Scan for viruses and threats on request.
  • SD card scanning.
  • Device performance optimization.
  • Battery consumption optimization.
  • Checking access rights for installed applications.
  • Powerful identity theft protection.
  • Remote cleaning of confidential data.
  • Detect and remotely lock the device.

So give Android antivirus a try. Many products have a free version — it will help to understand whether you like this software or not.

Testing Results From the Labs

How to choose Android antivirus.

Most leading antivirus test labs regularly conduct comprehensive testing of Android antivirus solutions, checking the level of protection, performance, and false positives for each mobile antivirus.
The test uses the latest versions of mobile antivirus available at the time of testing. Applications can update the signatures and databases in real-time via their cloud services.

Each software is tested by three points: protection, usability, and functionality (up to 1 point). The following apps in our review regularly receive the highest result:

  • Avast Mobile Security
  • AVG Mobile Security
  • Bitdefender Mobile Security
  • Kaspersky Mobile Antivirus
  • McAfee Mobile Security
  • Norton Mobile Security для Android

Here you can find some tests results from leading labs:

Malware Protection for Smartphone

  1. Whether you use an Android antivirus or not, follow these simple rules to protect your smartphone from potential malware:
  2. Download applications only from reliable sources. Bypass suspicious applications downloaded from the Internet.
  3. Be careful, even when accessing a trusted site. Before uploading anything to your device, check the file rating, read the comments, and see who built the app.
  4. Install regular security updates on your device. In its updates, Google improves the Android OS every time, patching up security holes.
  5. Stop using outdated apps and phones –- they are not safe. Always install the latest operating system updates and mobile apps. It’s the best way to keep your phone secure, more efficient, and easier than any anti-virus protection.
  6. Don’t view important information on your phone over public Wi-Fi. As a rule, in public places, the Internet connection is not password protected. Think carefully before using public Wi-Fi for serious purposes, as easy access makes them more vulnerable.
  7. Do not store the most valuable data on your phone. In this case, there is less chance of losing them.
  8. Use strong passwords. The password is direct access to all your information, so do not underestimate its importance.
  9. Keep your passwords in special applications.

Bonus Features

Antimalware and antivirus protection, as well as anti-theft modules, are core features of any Android antivirus. At the same time, many programs provide some additional features. They may include the following:

  • Backup of contacts and files. Although Google allows backing up the contacts, many antiviruses additionally backup certain files like documents or photos too their cloud storage.
  • Battery monitor. You can easily control which apps consume the battery resources the most.
  • Performance improvement. You can boost the device performance and close the background apps you are not currently using.
  • Wi-Fi control. The antivirus software will protect your traffic in insecure Wi-Fi networks.
  • Pairing with Android Wear. Such antiviruses as Bitdefender, Kaspersky, and McAfee send reminders to Android Wear.
  • Privacy risks report. The application scans the installed apps and notifies you if there are any privacy leaks or risks.
  • VPN. Buying an antivirus subscription, you get an unlimited VPN connection, so you do not need to pay for additional service.
  • Scheduled call blocking. You can set up, for example, receive calls at night from your family only.

    If you bother about your data and your information is secured, then you should go for BullGuard for Andriod antivirus; I just completed my back-up for all my android data.
