Even by installing apps from trusted sources, it is quite easy today to infect a tablet or phone. To avoid unpleasant consequences, it is enough to install one of the many antiviruses.
Why do you need an antivirus?
Unfortunately, even trusted mobile app stores still manage to infiltrate viruses. For example, Lookout Mobile Security specialists recently identified as many as thirty-two programs that passed all the pre-filters on Google Play (the main source of applications for devices running on the Android system). These applications disguised the malicious component as a standard ad unit.
A modern mobile antivirus must contain at least two modules: a scanner and a resident monitoring. The scanner checks applications only at the user's request; it is needed to identify a malicious application already installed on the device. Resident monitoring is constantly running on the device and constantly checks the state of the file system. It consumes a certain amount of resources, but it can detect a virus before installing it on the phone.
There are a number of free antiviruses that have proven to be effective
Norton Mobile Security Lite is a free version of the antivirus. This program is constantly updated, scans quickly and does not "hang" even the fastest devices. The application window in the free version is not very informative. In it, you can see the progress of the operation, information on the files being analyzed, and the general results of the virus scan.
Comodo Mobile Security is one of the most functional antiviruses out there. It has all the "gentlemanly" set of necessary functions - quickly scans applications in real time, monitors changes in the file system, and in addition is able to show the network activity of all applications separately, which can be very useful.
Antiy Labs AVL can detect atypical connections between files that may indicate a virus infection. For the rest, it is a typical antivirus that can do everything that the previous copies can do.
TrustGo Antivirus & Mobile Security differs from previous programs in the presence of a self-defense function (which means that the virus cannot disable it). This antivirus offers the ability to safely browse the Internet. Along the way, he checks applications for personal data leaks. It is more demanding on phone resources than previous samples.
BitDefender Antivirus Free is a very simple antivirus that completely checks all installed applications. It has a not very informative interface, but at the same time it is quite effective.
