ESET Mobile Security is the replacement for ESET Mobile Antivirus, which provided anti-malware and antispam functionality.
The program is offered free of charge, and can download updates if a network connection is present.
Initially the program gained popularity with IT workers in Eastern European countries, as ESET was based in Slovakia.It was created in 1987 by Miroslav Trnka and Peter Paško at the time when computer viruses started to become increasingly prevalent on PCs running DOS.Due to the limitations of the OS (lack of multitasking among others) it didn't feature any on-demand/on-access protection nor most of the other features of the current versions.On October 16, 2013, ESET Smart Security version 7.0 was released.It offers enhanced operation memory scanning and blocks misuses of known exploits.
