Good anti-virus program with extras ...

... Which also works in and of itself good and is less intrusive than about a few free ones. Was very reasonable and the free purchase of the full version as a promotional campaign, that pleased me very much. It is, as with good smartphone anti-virus software probably become common to a conglomerate of various functions. You can not only find and destroy viruses, but also his cell phone in case of loss of lock or remote locations, make it emit sounds and if necessary to delete all data. At the same time, the software monitors the battery level and can end in the background running apps to improve the performance of the device. For the remote control, there is a website where you log in to another device (eg PC) and can control the functions. The Ales goes slightly out of hand and is largely foolproof.
The problem is that the app on my Galaxy S4, formerly öfters- now back at least now and then, makes for a very high processor utilization and it has brought with it a considerable time repeatedly crash. The change from the base to the full version has helped somewhat, stop all I could do this only through the installation of a second anti-virus package from the Play Store. Although this is intrusive in the advertising insertion and logs otherwise felt every quarter of an hour, but shows me when AVG again using too many resources and can be the appropriate AVG functions then quit. This provides a remedy and after several twists and turns to the apparently badly verkrotzten from manufacturers Android system, I ask myself why not and let everything as it is now actual never change a running system!
Because so holds double stitched better in this case, I'll stay with my solution, a point deduction, there is for triggering a lack of running stability by AVG.
