Define "no antivirus". A fresh OS install? Windows has a built in AV. Not perfect, but there it is.

went on Google to download steam and maybe check pcgamer?
And then 90 minutes later, after you have clicked here and there...who knows where you went.

If you are careful, sure. No problem. Are you that careful?
