Windows 10: Why is my game and the website that I watch anime on blocked? Fix this please

I've been playing a game called Flyff for many years and it's a game that you have to download in order to play. I've downloaded the game before on my current pc. When I started the game, it didn't load. I was getting frustrated afterwards, so I restarted my pc twice. After many tries, I uninstalled the game then redownload it. While it was downloading the file at the very bottom of my browser, it stopped and "warned" me that my game, Flyff, was block and can cause harm to my pc. I never seen that before. The website that I use to watch anime is called Aniwatch and I've been using it lately. It caused no problem to my pc. Like it doesn't slow my pc or have random ads popping up. I would love to have the rights to be informed when something is or can be harmful to my pc. Please fix this.
