WEIRD THINGS OCCURING

magenta3104728

    I have a Samsung Galaxy S7.  Under settings, the service provider is listed as a GIGA LTE, KT twophone service.  I also have two device maintenance options and two applications options. This is odd.  I had some sort of malware because I received a pop up saying that I have four virus.  I did not click on anything and went into the setting to clear the cache and noticed these odd things under settings.  Please advise.
