I shared a YouTube video gave viruses.

I am using my YouTube app on my phone and I shared a video through gmail like I usually do for a certain friend who’s usually at his PC. This time however he said it took him to YouTube but also opened internet explorer and downloaded 10 viruses to his PC. So now he’s reinstalling Windows, any ideas? I try googling from my phone and if I put YouTube link and virus together I get viral video links lol. Avast says there’s nothing on my phone. Here’s the only line of the email, and link I said I just clicked on share like I’ve always done.
