Possible Virus

So I recently -very accidentally- opened an adult site via a pop-up that appeared last second. I closed out as soon as I could, but I didnt see that there was a second tab opened - warning that I had 13 viruses and my phone was 68% compromised and to download the Protection 360 app. Tbh I freaked out an downloaded it, only to find out later through research that I am SO not supposed to do that. I then Cleared my website history and cookies and reset my phone to factory settings. Is there anything I can do to see if there are actually viruses on that phone now? Because I am honestly a little scared to use it...
