Does original SCP have any viruses? Why do I remember to download it at some time and when I wanted to erase the game some data on my PC was deleted and I could not open anything until it was fixed from nothing, was it for the game? download it directly from the page. (i used translator, my english is not so good) but that was all, i'm just a little scary of downloading scp again

SCP Containment Breach and SCP-087-B don't contain a virus, you might have installed one before and you didn't noticed it.
