How does online checking for Android viruses work and what does it give?
Services with similar functionality are offered by antivirus software developers. For example, online scanning is available from ESET, Kaspersky Online Scanner, Doctor Web. The advantages are obvious:
- no need to download and install antivirus on your phone;
- you don’t have to worry that your gadget won’t have enough memory;
- there are no problems with periodic checks and threat messages;
- no need to pay for the purchase of the application or software subscription.
The instructions are simple:
- we go to a site / service that provides the ability to check online;
- connect the phone to the PC via a cable (optional);
- start the process of checking the external media and wait for it to complete;
- we receive notifications about the system status and detected threats.
But checking for viruses without installation on Android also has serious disadvantages. For example, some services can only detect malware on the device. You cannot automatically delete it or quarantine it. The user will not always understand how to do this manually (the installed antivirus on Android executes commands in a couple of clicks). There are other disadvantages:
- the number of checks is limited;
- the system can scan only files or only links;
- the list of databases is limited;
- scanning of individual files (selective) may not be available, there is a risk of false positives.

The application scans installed applications for potential malicious activity, and its search speed is slightly faster than other similar applications. The app has an excellent built-in basic antivirus application that scans and shows potential vulnerabilities.
. Mobile Security: VPN Proxy & WiFi Network
McAfee is one of the most famous antiviruses. It is also one of the heaviest. The app includes scanning, anti-theft, spyware, and blocking features. In addition, the antivirus can take a photo of a potential phone thief, record his location in the cloud before turning off the phone, and do other useful things.
McAfee also has a variety of standalone apps for different purposes. Its interface is old and does not look very aesthetically pleasing. In addition, it has features that work only on PRO and to upgrade to the professional version, you need to create an account.

4 tips on which antivirus to choose for your phone
There are too many software to protect your device from threats. For an inexperienced user, it may be difficult to understand. To make your choice easier, you need to understand what criteria you should use to choose an antivirus. Here are the most important parameters to pay attention to:
- Percentage of detected threats.
It is the detection rate that shows how reliable the antivirus is. The higher it is, the better. The program must recognize all suspicious files and types of threats. - Antivirus errors
. If the error rate is high, then the antivirus often raises false alarms and blocks access to files or sites that do not pose any threat. This interferes with the full use of the device. - Impact on system performance.
This parameter shows the speed of the program and how it affects the operation of the OS. The less the software drains the battery and slows down the device, the better. A good antivirus will work almost unnoticed. - Availability of additional functions.
Good antiviruses contain many useful functions, in addition to protection. This could be parental controls, call blocking or SMS filtering, backup, etc. Here it is worth starting from your own needs.
AVG
AVG is another famous name in the antivirus field. In fact, it’s the same as AVAST. And VAST actually acquired AVG back in 2020. Thus, the operation of both antiviruses is the same. You can scan your phone and look for potential vulnerabilities in much the same way.
The app has anti-theft features and tracking via Google Maps, but it does not have access to a root firewall like AVAST. So they are different enough to be different products. Please don’t use phone booster feature because they are not effective. We don’t know why antivirus apps so often have junk features.
ESET
ESET is another famous name in the antivirus world. The app has a decent set of features including scanning, anti-theft, security audit feature, scan scheduling, and more. The installation process is a bit intrusive. The app is one of the few that requires an email address. Otherwise it works quite well. You get a one month free trial after installation.
Ahnlab v3 mobile security
Program from South Korean developers. The antivirus is not yet widespread among Russian-speaking users, but has proven itself well abroad. According to test results, AhnLab V3 Mobile Security demonstrated a very high level of threat detection.
The program is not demanding on device resources, so it is suitable even for older phone models. The developers have introduced a unique “Hidden Gallery” feature, which helps hide personal photos from prying eyes. And the “Quick Clean” function allows you to delete all activity history data in different applications.
Android 11 will not be released on Huawei and honor smartphones, they will be immediately updated to harmonyos
At the Huawei Developer Conference 2020, the company presented EMUI 11
, the latest version of its mobile software. It was also announced the launch of beta testing for several smartphone models.
As we learned, these builds are based on Android 10 and not Android 11 as expected. The company later provided further clarification on this matter. First, the Chinese telecom giant confirmed that some select Android 11 features will be included in EMUI 11. This means that the core of the final version of EMUI 11 will likely remain Android 10, just like the beta versions.
Due to the US ban, Huawei was unable to collaborate with Google to develop its new software based on the latest version of Android. In a second statement, the company said that devices running EMUI 11, which the company claims is based on distributed technology, could be upgraded to HarmonyOS in the future. However, this statement does not mention specific models that will be able to update. It is also unknown whether the HarmonyOS update will be forced or optional.
The complete list was published yesterday
Huawei and Honor smartphones and tablets that will receive EMUI 11 and Magic UI 4.0.

AVG AntiVirus FREE works in real time, and on-demand file scanning is also available. Like most other mobile antiviruses, AVG scans the SD card and internal memory of the phone.

Private data, applications are blocked by a pin code. You can restrict access to instant messengers, photos and videos on your phone. Another protection function is to block the smartphone after changing the SIM card.
AVG also offers the function of permanently deleting files in the phone memory or on the SD card. This may be necessary, for example, if a smartphone/tablet is being prepared for sale or the data is of extreme importance. Personal information erased in this way cannot be restored.
AVG AntiVirus also has other, less important tools: a task manager, a file cleaner and a battery optimizer (Power Save). There is no particular need for them: the latest versions of Android have built-in optimization tools.

Cm security (security master) — antivirus optimized for Intel devices
What can we say, considering in order the best antiviruses for Android: if you need fast and discreet operation of the application, then you should pay attention to the CM Security mobile antivirus in the FREE version. We could list the program’s capabilities for a long time, but we will only focus on the important features of one of the best free antiviruses.
As for the important differences between CM Security and its competitors, they lie in the fact that you get the opportunity to “catch an intruder” who is reading your correspondence or trying to gain access to the device. If this is unauthorized access, then the antivirus for Android will take a photo of the intruder with the front camera of the smartphone and send it to you by email. In addition, a photo will be taken even after entering the password incorrectly twice when unlocking a smartphone or tablet.

Dr.web (light, security space)

Download link
The software claims to be the “best free antivirus for android”.
Dr.web light
This antivirus ends with the word “Light”, but, in fact, I would not say that. It has quite a lot of capabilities to protect the gadget from various types of pests.
Doctor Web has already established itself on computers as one of the best. It functions quite quickly, without loading the CPU and RAM, which is comparable to antiviruses that have many functions. This software has excellent optimization for Android phones and tablets.
The application has excellent customization and it allows you to select a scan mode, quick or full. Also, you can simply specify only a folder or a specific drive in the settings, and Doctor Web will scan only them.
Dr.web light – free, lightweight antivirus for smartphones

Despite the prefix Light, Dr. Web offers a full range of basic features that will protect your mobile device from malware.
What is important, Dr. Web works quickly without loading the processor and RAM, as more functional competitors do. The program is perfectly optimized for working on Android smartphones and tablets, so background protection will be invisible to the user. Even on devices with 512 MB of RAM, Doctor is very fast and does not drain the battery.
The antivirus is highly customizable and allows you to choose a scanning mode, full or fast, as in the desktop version of Doctor Web. If you need to scan a folder or disk for viruses, this is not a problem; you just need to specify them before starting the scan.
If you often check the contents of your phone and want the antivirus to be always at hand, you can add a special Dr. widget to your home screen. Web Light. With its help, it is convenient to check downloaded Internet content. However, there is no particular need for regular checking, since SpIDer Guard monitor provides real-time protection for the phone.
Let’s note other possibilities. Dr. Web Lite successfully copes with blocking viruses. If the device is blocked, the antivirus will eliminate the threat and remove protection. If there is no virus in the Dr Web database, Origins Tracing™ technology will help identify a potential threat by analyzing the behavior of running processes.
Dr. Web Lite is regularly updated along with anti-virus databases (as of November 9, 2020, the last update occurred on October 19, 2020).

Unfortunately, access to it is only provided for a month. The premium version adds real-time protection, application blocking and other interesting but optional features.
Users like the absence of useless utilities in Kaspersky and the completely Russian interface. The developer tried to make the application as effective as possible, equipping it with everything that the owner of a modern smartphone might need.
Against this background, the cost of the paid version of 499 rubles per year seems quite modest. If you are looking for an antivirus in Russian, be sure to take a closer look at the brainchild of Kaspersky Lab.

Antivirus 360 security
Any excellent antivirus has its own protective methods. When you purchase 360 Security, you become the owner of an interesting bonus. We will find out what this bonus is below.
Antivirus 360 security — another good antivirus for Android
As a rule, any of the antiviruses that claim to be the best or just good has a basic set of protective functions. In the case of the 360 Security antivirus for Android (distributed free of charge), you get an interesting bonus. Which? Read on.
Main features of the 360 Security antivirus in the Android edition:
Additional features of 360 Security:
An interesting feature of the 360 Security antivirus is the “do-it-yourself” function for cleaning the Android system. Shake your smartphone or tablet and automatic system cleaning will start. An interesting idea, although completely meaningless (why does a mobile antivirus need it?).
Anti-phishing module
KIS, like any firewall, works in the background, insignificantly loading the resources of the phone/tablet. If a user tries to open a link that leads to a fraudulent resource, Kaspersky Internet Security blocks the download and issues a notification.
Blocking access to programs
Kaspersky also has functionality such as blocking programs. If a password has not been entered for a certain application, it simply will not be able to start. Accordingly, it becomes unrealistic to take information from it.
Questions and Answers

Answer. Both Dr Web and Avast are quite effective antiviruses. Please note, however, that to ensure security, you need to update virus databases regularly (especially if information about new viruses for Android appears in the news).

Protecting your privacy — Huawei Russia

All apps published on the AppGallery store undergo a four-step security review to ensure they do not compromise your privacy. The test results for each application are available on the application details page.

If violations are detected, the company contacts the developer and asks him to immediately fix the problem. If a developer does not comply with this requirement, their application will be removed from the AppGallery.
When installed from AppGallery, some apps request access to your personal information, including your location or contacts. You will be prompted to allow or deny access. Access rights are granted to applications only with your consent. You can deny access at any time.
In addition, the company ensures that AppGallery apps are denied full access to your data, as well as access to certain types of data on your device. The company has adopted a strict privacy policy, is taking appropriate measures and will continue to improve mechanisms for protecting users’ personal data. The Company respects your right to privacy.
Anti-theft
If a mobile phone falls into the wrong hands after being lost and/or is stolen, Kaspersky will determine its location. If the thief is nearby, you can activate the siren on the stolen phone or take a photo and send it by email.

Do you need an antivirus for Android or not?
Some say that software is required to protect against unwanted processes. Others are confident that for the gadget to operate safely, systems built into the OS, such as the Google Play Protect antivirus, are sufficient.
But statistics show that default applications are not enough:
- in 2020, QR code scanners and alarm clocks were found in the official store infected with the AsiaHitGroup Trojan, which caught information about users;
- on Google Play, Trend Micro cyber security specialists found 36 programs that, after installation, showed unwanted ads and gained access to personal data.
Antivirus for smartphones is one of the measures to protect confidential information. People who don’t care about online security face common problems:
As a result, we can draw a simple conclusion: you need a good antivirus program. It is used to:
- find potential threats in software;
- scan WiFi;
- delete unnecessary files (cleanup recovery);

Not every one of them needs this mode. Also, the antivirus kernel can make the functioning of the Android OS gadget slower.
