The source code of the Android operating system is available to many software developers. This factor is the main reason that a large number of viruses already exist for a relatively young OS.
The bulk of virus programs for the Android operating system can be divided into several categories. The most dangerous of these are Trojans that use SMS technology. Such software is referred to the Android. SmsSend group. The obvious harm of SMS Trojans is the loss of funds located on the subscriber account of a client of mobile operators. The virus sends out expensive SMS messages using a database of paid short numbers.
It is important to note that the described type of virus is dangerous only for smartphone owners. Android tablet computers are not designed to send short messages. Exceptions can be made by devices that support work with GPRS and 3G networks. Some models of such tablets can partially function as a smartphone.
Tablet PC owners should pay special attention to protection against Trojan horses. This type of virus is designed to steal confidential information. Basically we are talking about accounts in various social networks and e-mail boxes. In addition, similar programs can cause the appearance of various ad modules. Removing such windows when working with a tablet is much more difficult.
Practice shows that the presence of certain virus modules can significantly reduce the overall performance of a tablet computer. For owners of budget models of tablets, this is a very serious problem. New Android viruses are used by cybercriminals to connect the device to the desired botnet network. After that, the tablet PC, without user intervention, starts periodically sending requests to Internet servers.
To exclude the possibility of installing virus software, it is recommended to carefully check each new application. In this case, it is better not to allow utilities to access personal information and the Internet, if this is not necessary.
