Many users believe that their tablet is completely safe during Internet sessions. However, the Android system running on tablets has open source code, which means that it is poorly protected from various malicious programs that can steal information, block the operation of the device, etc. How to detect the problem and about effective ways to fix it, we will tell in our article.
There are a number of signs indicating a possible viral infection:
- unstable operation of the OS and individual programs, accompanied by crashes and a slow reaction to user actions,
- Internet traffic has increased significantly
- slow file loading, browser speed drops,
- the appearance of extraneous messages during a reboot (dialog boxes offering to win a cash prize, etc.).
There are several ways to check.
- In online mode. Specialized sites (vms.drweb.ru, virus.total, etc.) contain free scanners. Choose the right tool, download and check the file that you think is suspicious.
However, this method has disadvantages. Objects of a certain size are allowed for loading, and simultaneous verification of several elements is not provided.
- Directly on the tablet. To check the level of danger, you need to download an antivirus, it may be a trial version. Software can be found in the Play Market, where there are both paid and free applications.
On a note! Devices with Android above 4 have a built-in scanner that can detect the most common threats.
- Check by PC. You need to connect the tablet to a stationary computer or laptop on which the licensed product is installed. When you find the tablet must be cleaned.
Important! In order to avoid additional problems, before connecting the tablet, enable a full scan of the computer itself using antivirus. When he confirms that there are no problems in the system, you can connect the device and activate its full scan.
The leading positions are occupied by applications:
- Dr. Web,
- Kaspersky Internet Security,
- ESET Mobile Security.
Reference! The rating is determined by the number of downloads and users' assessment of the level of effectiveness. Russian companies are confidently holding the lead, and only the Slovak company ESET was able to win the third position.
Briefly consider the advantages and disadvantages of software development.
Dr. Web, in addition to the commercial version, is also available in the free version of Light.
Distinctive features of a freeware utility: there is a whole set of necessary tools, easy operation without system load. Effective detection of most types of threats, ease of management, regularly updated updates. Disadvantages of free software: protection against spam and data theft is not provided (available in the premium version).
Kaspersky Lab product has two modifications: paid software and trial version, designed for 30 days of use (with incomplete functionality). The program works in real time, on demand it performs a full or partial scan. There is a module that detects fraudulent sites. If the device is lost, the program will determine its location, blocking applications on the device will save personal data intact. Databases are regularly updated. Scanning and removal (treatment, quarantine) of detected problems are available in the trial product.
Software from ESET is available in two versions: a trial version, available for a month (with full functionality), and a paid program.
Important! After 30 days, the utility remains available, but with a limited set of features. You can search for and eliminate system vulnerabilities, malicious and spyware applications, conduct selective scanning and use the anti-theft function when the device is lost.
The commercial version is supplemented by a module for detecting fraudulent sites, verification and protection of applications.
The removal method depends on which threat detection method you used. Let's consider in order:
If the gadget has a downloaded and installed antivirus (commercial or trial version), then upon completion of the scanning process, it will offer solutions to the problem. This can be a complete deletion of the file, its treatment or quarantine.
On a note! In software options, you can set a priority: the utility will automatically apply the tools to eliminate detected threats and then only display messages about completed operations, or ask the owner for consent to the measures applied.
When connected to a PC, the procedure will be the same. Additionally:
In the settings of the device, select the section "Use as a multimedia device", in the section "My Computer" we find and open the connected device. We launch anti-virus software and specify the tablet as an object for scanning.
Antiviruses are configured by the manufacturer so that they automatically act in an optimal way. For example, malware is completely removed, files infected by them are treated (if possible), components of the system itself are usually quarantined.
When using online scanners, the user receives a full report of detected threats. However, these tools can only provide a list of harmful elements, they are not capable of destroying them or treating the consequences of infection. The owner takes the next steps on his own: removes viruses and decides what to do with the damaged files. It is not always possible to do this correctly, especially if there are problems with system components.
We looked at ways to detect viruses and methods to combat them. If the problem persists, then the system is seriously damaged, and you must call the wizard or contact the service center.
