One of the problems Google faces when developing its mobility-oriented operating system is malware. The truth is that it is becoming almost an obsession for this company and, therefore, it has decided to take new action on the matter in Android 4.2.
It was expected that security will be improved in this new version of the operating system that is included in Nexus 4 manufactured by LG, and those of Mountain View have complied. According to an article in Computer World, it is confirmed that Google has included greater security in Android and, in particular, against malware and, therefore, that end users do not have bad security experiences when using the latest version of Jelly Bean.
According to this medium, the new advanced protection runs in the background in real time and does not affect the use of the terminal, so users are not affected ... but they are protected. The review it performs is complete both for applications (come from Google Play or another source) and potentially dangerous files.
This is how protection works
When an installation is carried out, this service runs and reviews the process and, to do so, checks against a database if what is being installed is "clean" or includes malicious code. In the event that a problem is found or something abnormal is detected, the installation is stopped to prevent possible infections. In the end, the new addition is similar to the one used in Google Play, which is why examinations of the applications are now carried out in two ways.
Such is the power of this new protection included in Android 4.2, that is able to check even SMS messages and the telephone numbers from which the message is received or sent, to check if it is part of a malicious or scam network. Therefore, the security seems to have improved very significantly with the review of Jelly Bean, something that was needed and that Google has done. Android is becoming more and more secure.
But it is also a collection of personal data as well, so our privacy is open
