hello, i have a lg g3 running on andriod 5.0.1. ive kept it on stock settings. at the time i got the virus, i hadnt even logged in a google account, so it wasnt because i downloaded a bad app. when im using the browser, it redirects to a website saying that my phone is infected. i factory reset the phone and when i started using the browser again, i was redirected to the same page. at this point, i decided to click the option below which took me to the du cleaner app on the play store. ive attached screenshots of the page i was directed to. thanks in advance.
