If it is an update by Samsung, it is safe. They make every system update in their security system, so I can say that it is worse not updating rather than updating. It would be best if you were more accurate only with software that is not licensed. This kind of software can harm your files on your personal computer. But I don't have problems with it, because I am using only licensed software. O don't like risking, and I would better pay some money and buy the licensed version from softwaredeal store rather than the risk with my security.
