How to find and remove a virus on Android?

No matter how users cussed that the operating system "Android" is vulnerable to various kinds of viruses, the main cause of infection is the illiteracy of the person himself. How does the threat come in the phone or tablet? For example, the user wanted to download a broken version of the paid game. This manipulation in 80% of cases threatens infection with the virus. Another common situation: there is a message in any social network with a link. Few will resist the temptation to move on it. At this stage, the threat penetrates directly into the phone. About what to do and how to protect yourself from this situation, let's talk in this article.

Counterfeits

Often, the virus on "Android" can be hidden under completely harmless applications: browsers, navigators, games, players, books and, most interestingly, antiviruses.

There are two types of threats. One of them is called "fake". It got its name not by chance. Such a component can look like a known application, but inside it you have a malicious code. Such a program (viruses on "Android" can be masked by favorite "VKontakte", "Classmates", etc.) at the opening begins to act actively.

"Trojan horse"

The second type of threats received a general name - "Trojan Horse". Such viruses are more harmful, they are difficult to calculate, accordingly, it is almost impossible to delete if the user is a novice. They are built into any application that is frequently launched on the phone or tablet, changing its source code.

We'll talk about ways to remove such threats, but you need to know that most of them are located in the Downloads folder.

What are the dangerous viruses?

The virus on "Android" can perform many actions. The most popular ones will be discussed below.

• The most common action that an unsafe component does is to make calls and send messages. All this is done in the background, so the person does not even notice it. The action of the virus stops when the funds in the account run out. After replenishment, it is activated again.
• Another type of virus is collecting information and sending it to the appropriate server. As a rule, passwords and logins, data from bank cards, come under the sight. Rarely when viruses steal information from the device itself.
• The rest of the infected components block the operation of the smartphone or tablet, which they hit. Often they are banners that extort money.

How to distinguish a "healthy" application from a virus?

The vast majority of viruses, which are quickly and easily installed on devices, are written by non-professional programmers. They are necessary for easy money making. That's why it's quite easy to calculate such threats - just look at the list of permissions for the installed application. As soon as this virus appears on Android (on the phone or tablet), and the consumer activates it on the system, he immediately starts sending messages to paid numbers or calling them.

Not all applications work this way. However, these are the most common and, by the way, easily eliminated.

What should I look for when installing applications from third-party resources? The first bell - if the program makes unclear requests about:

• Access to the camera - it means that the developer wanted to shoot something;
• Access to memory and Internet connection - you need files from your phone;
• Administrator rights - are needed in order to block the screen advertising.

A qualitative virus on "Android" is harder to identify. But you need to be alerted if the application is downloaded from an incomprehensible resource and requests the right to perform paid functions - such software is 99% virus.

How can I delete a virus if I have access to the menu?

A public and one of the easiest ways to get rid of viruses is described in this section. If the consumer has realized that a threat has settled in his phone or tablet, it is worth taking active steps:

1. To get started, you must immediately remove the SIM card. This step will help to secure the account of the owner from unpredictable waste.
2. After that, you should download any antivirus via Wi-Fi. To recommend some kind of special can not, since most of the known defenders are updated every time, so they are all highly effective. The most popular ones are Doctor Web, Kaspersky.
3. You must run a detailed scan and remove any existing threats.
4. After the whole procedure, you should remove the antivirus.
5. You need to download the second antivirus. The first one must be removed for the reason that sometimes two similar applications can not work simultaneously on the same device.
6. After checking the device and removing all suspicious programs, you must disable access to administrator rights for all installed software. If suddenly one of the programs does not do this (which already makes you think), you need to load the device in a safe mode and perform this manipulation from it.
7. After that, you need to go to the installed applications and remove from the device those that are not familiar to the owner.
8. The last step is to reboot the device.

For those who have not been helped by the above method, you can recommend resetting the settings to factory settings. Typically, this erases all the viruses that were installed. But this option will not be useful for components built into the system itself. So, the most simple way how to remove a virus from the phone "Android", has been described in detail and will be able to help most consumers. If you still can not solve the problem yourself, then one thing remains - contact the service center.

How can I remove a virus from my phone or tablet if I can not access the menu?

As a rule, there is no access to the menu if the screen is "captured" by a banner that requires replenishing the account of a phone number or bank card. What to do in this situation?

Attention! In no case is it necessary to transfer money to the specified requisites. Scammers do not unlock the phone.

1. The first thing to do is remove the SIM card from the device. Otherwise, the virus can devastate it in a short time.
2. You must download the phone in safe mode. No need to worry: the banner will not appear in this case, since only the basic applications necessary for operating the operating system will work.
3. You should go to the menu and disable all the programs with administrator rights.
4. You must uninstall unknown applications.
5. Next, restart the device.

If it does not help, the standard way to reset the settings will be a reasonable solution.

Change firmware

The question of how to remove the virus from "Android", which is deeply "stitched" in the firmware, is of interest to many people. Let's consider some effective ways.

Immediately need to say that a banal reset of settings will not help. Such viruses are built into the operating system and get root-rights, which (according to the standard) even the user does not have.

The most effective and, perhaps, the easiest solution for experienced owners is to change the firmware. If you care about the integrity of all the files that are on the device, you can always make a "backup". However, some devices have a similar function in the public domain, while others require administrator rights for this. Firmware is best downloaded from the official resource. If there is a desire, you can install any other, not necessarily the one that is factory. It is enough to use the search engine and find the right version for your phone.

Root-rights

If the consumer is an advanced user, you can get root-rights and manually get rid of the virus. It should be noted that some threats are considered standard and are personally built into the system. Often, such software does not deal with the collection of money or data. Such a virus just occasionally displays ads over the windows. You can close it with the help of a "cross". Many people ask themselves the question: "How to remove viruses from Android through a computer and really do it?" This is often how the user gets super administrator rights. By the way, you can also change the firmware via a computer. Instructions for installing root-rights are available on the Internet. From ourselves we add that this method is suitable for those who know which application is viral.

The result

The article describes in detail the standard and more complex ways to get rid of your device from infected components. Now it's not so scary to deal with the problem when viruses from Android are not deleted. Such systemic threats can cause serious consequences if you do not deal with them in advance. Therefore it is worth to be as watchful as possible. You do not need to download games from extraneous sources or navigate through strange links.

To remove a virus from the phone ("Android") through the computer, you need to have the necessary skills. And if they are not, it's best to contact either friends who have repeatedly changed their firmware or installed root-rights, or to a service center.
