Basically, i'm pretty new and wanted to start programming my own roguelike, so i looked at roguebasin's c++ libtcod tutorial - while reading it I clicked on a hyperlink that supposedly was a link to libtcod's manual, but instead it opened a site that offered something that seemed to be a reCaptcha, that after being ticked off gave me a pop up saying something along the lines of "To be more certain that you are not a bot, click 'windows key + R' then Ctrl+V and then Enter" which i assume is a virus of some kind.
(i'm pretty new + english is not my first language + not as experienced programming so if ANYTHING i said doesn't make sense please do say something so i can explain myself better/ learn something from somebody who is more knowledgeable than me)
