There's a virus on my tablet?
I have a lenovo ideatab and sometimes ( different apps like candy crush saga and pinterest) a little rectangle appears in the upper left corner of the screen. It is pink and yellow and it says "Lou Memory" or that's what it looks like to me. Usually it does nothing, but quite often, it closes my app and brings me to my home page. This wouldn't be a problem except it also changes my background to black. Has anyone else seen this before? I don't know what to do!
