There's nothing worse for you as a gamer, it's getting a VAC-ban. VAK is a program from Steam that blocks access to your favorite game permanently, in other words, forever. The developers have repeatedly reported that this protection has never failed and blocks players for "game crimes" - the use of cheats.
There are a lot of articles on the Internet about how to remove a ban, but, unfortunately, none of them works. What to do, you ask yourself a question. Is it possible to deceive the anti-cheat? The answer is no. If you are sure that you were banned "illegally", then safely write to the technical support of Steam. If they find your story to be like the truth, you will certainly remove the ill-fated ban.
Therefore, before you have to raise your hand to use various cheats and other programs, think about the possible consequences.
