Hi. Tonight I was on Facebook looking at stuff and browsing through it's everyday normal stories. Suddenly this big starts freaking out on my phone. Took up the whole page. It said "Android has Expired." That warning came with a "Install Now". I panicked and installed 360 Security antivirus. This app has made my phone wonky and heats it up to all heck so I deleted it-yesterday. I have deleted this app again since. I'm not on Facebook,currently on here looking for advice. No screen shot because my mistake of panicking and not reading the whole warning has left me curious,confused and feeling very brain-dead for not reading it all. I have McAfee for security so I'm going to run a full scan but what is this all about? I know it's not my service because my bill is paid. Please help, I'd be very grateful.
