So a day or two ago, I opened Chrome on my tablet and another window opened saying I needed to update my device. Yesterday it said that my tablet had a virus and if I didn't update, the system will get worse, maybe even fail. Today it says my battery is "seriously" overcharged, and if I don't update, the system may fail completely. It's coming from a website called qqmars.com, which I have never heard if. I tried researching it but found nothing. I am horrible with technology and I have no idea what to do when problems like this arise. I emptied my cache and my cookies, but that clearly did not work. I don't really get on websites through my tablet, and on the rare occasion that I do, it's always a trusted one. I'm 90% sure this is just a scam, but I still don't know what to do. Thoughts?
