Fucking up my files

I recently downloaded a game from a website, it took 4 hours to download, and when it was done it said "There could be some files that are recognised by malware. These won't harm your computer." So I just started the game and guess what? AVG put some files "in quarantine" and somehow, once I try to restore the files and open the game, it say's that some files can't be found. You guys better fix this shit because I have to reinstall the game rn, which takes another 4 hours of my life waiting. I deleted AVG right away, because 1: You always get shitty messages like "oh you could optimise your pc" bla bla. most of the things they detect aren't even viruses. Y'all can go do what my name says.
