VAC banned for no reason?

Okay lets go through this reasonably:

Tell me if you were running the following:

A) Mods (can be as simple as a skin pack)
B) Background processes
C) Steam Beta.

Please don't spam Steam Support to unban you. You are wasting time. Steam Support is very poor and you are making it worse for other people by spamming. You won't be unbanned because you asked, they won't give you any information, they won't tell you if you were hacked and they don't care if the hacker cheated. Your account is your responsibility. If you really think you didn't cheat you can send them ONE ticket asking to check it again. They will check it and if they will respond something like "We can't give you any information." it means they are 100% sure you cheated. You can do nothing about it other than deal with it or hope it was an error and they will unban you automatically (your spam will have no influence on this).

Thank you. /EOT

In The U.S. we have systems that work. We have machines that can tell who is not telling the truth. We also have drug screens that tell if someone has used illegal drugs. This helps us lock up the bad people. Now we are so advanced we can have steam bans issued with little or no human interaction. What could go wrong?

There's always a solution....Hack steam and "unban" yourself. Works everytime.

As far as I know off bans on Steam,PSN & XBL are ALWAYS deserved so there has to be hacked or cheated on your profile b4 whether it was you or not. Bans from steam always take a while bc they happen in batches. What could have happened if you don't hack is that you played a game with graphical mods as playing CS etc. with ENB or other graphical mods because this is a known cause for getting VAC banned. Family sharing and certain background progresses could also be the cause for this. In other words you can't get "wrongly" VAC banned, you could have installed the wrong graphical mod, have the wrong process running in the background or a friend/family member you share your games with has cheated tho.
Steam support won't help you just a heads up, they get mails like that all the time and most people just lie. VAC ban shouldn't be tgo bad for you tho as you said you didn't play any VAC games. Only thing you could do is maybe ask support what game you got banned for if you're curious.

Well, here we go with a lot of reasons: "Unlocked: 4 Jul, 2011 @ 9:48am"...

TF2 achievements :)

Here is a cent from me:
Every time I see such kind of a problem I am posting this. So...

I couldn't find screenshots yet again (and I'm sad because of that D: ) but there was a person who posted his whole conversation with Steam support. He got VAC banned without any reason and argued with support about it. After many replies from bot and then tens of replies from various people he finally got unbanned. Support said something like: "There was an error in our system. We apologize and your account has been unbanned.", eventhough they were like: "Account cannot be unbanned." whole time.
TLDR version: Yeah - it IS POSSIBLE to get rid of VAC ban on Your account.

Edit. I've just read few last comments and yeah - if You have ever unlocked some achievvements using some kind of programs then don't even try contacting Steam Support - they won't unban You.

Go to support steam and ask why you get ban on VAC
Steam never unban VAC player

Nobody is banned for no reason. VAC bans do not occur when you are caught cheating, but weeks or months afterwards.

There HAVE been instances of false VAC bans - however, these usually occur in huge waves and are typically removed right after.

There's the infamous MW2 hacked lobbies thing that still hasn't been reversed and is unlikely to ever be.

In any case, figure out which game you were banned in, why, do a virus scan, and go contact support, although they'll just say "VAC bans are never lifted and we won't tell you why you were banned."

Also, if you're family sharing your library, go yell very loudly at anyone who your library is shared with. If you family share and someone cheats with your game, you get banned.

Actually, there is one offense for Dota 2 that warrants a VAC ban. Using external tools attached to Dota 2: 30 day game suspension.
Try to start Dota 2 to find it out.

I got my old account VAC banned since 2006 only for have instaled "Cheat Engine", i didn't use it on Steam never, i used that for flash games. But Steam detected i got this things installed, only installed, and VAC banned me from CS:Source and Half-Life Deathmatch.

Once OP realises how VAC actually works, he would stop making these topics filled with lies. Sad people still don't realise that the VAC detected cheats on his system.

I donot know if some one took the time to post these in between all the "Hurr Durr U HaXor. Praise Lord Gaben's glorious no mistake VAC" bull.... , there is proof of false bans AND reversed bans . VAC has made mistakes and not just the bulk cases reported in the wiki, But rather more recent Individual cases , Like this one where the user finally got unbanned after a long painful back and forth with the steam support. There is a lot of info there, which u might want to give a read.

There is also THIS GROUP which collects people who have been unbanned from VAC. A lot of usefull info there as well.

While achievement servers donot get u vac banned, Family Sharing definitely can, as mentioned clearly here , which might be the situation in ur case if what u say is true.

 Will I be punished for any cheating or fraud conducted by other users while playing my games?
 Your Family Library Sharing privileges may be revoked and your account may also be VAC banned if your library is used by others to conduct cheating or fraud. Additionally, VAC-banned games cannot be shared. We recommend you only authorize familiar computers you know to be secure. And as always, never give your password to anyone.

Never seen a VAC Ban reversed, its bad for steam business, worst thing is you will keep that mark on your profile forever , i wish good luck buddy.

As far as I'm aware Valve doesn't say why you were banned or when the hacking event happened. The only time they lifted bans was when they thought people were hacking but were only changing some textures and that happened to a lot of people.
If you enabled family sharing then that might also be a reason because others can get you banned too, I think...

Having a degree in computer science, it's really interesting to see how many people believe that modern automated systems are entirely fail-proof. It's almost like belief in magic.
Wish you luck with getting this straight.
P.S. And still, of all obvious cheaters I've reported, I've seen only one being vac-banned, even though in many cases it's enough to see a few minutes of match replay (things like constant aiming at someone who's behind a wall or spamming hs through smoke).

You never can get unban sorry bro this Discussion can be now closed.

Cheater what are you talking about, VAC Never simply bans, and to whom you opravdyvaeshsya?

There is always a reason. It might be bad, but it exists.

Does Valve gave random VAC bans to people that weren't cheaters? YES, THEY DID. Happens in like 1 in a million, but it does happen.
Will Steam Support help you? NO THEY WON'T. You can try, but you'll get few automated responses, then "sorry, support can't talk about vac bans". You won't even learn why you were banned.

Your only way to get unbanned, if you really weren't cheating in any way (and that includes like using public PC where someone randomly could install cheats) - asking if there was some weird VAC banning lately on reddit/dota2 and have enough luck to get some Valve Employee check it. And that still only works if you are known user of reddit.

Yes u or someone else use program to unlock TF2 Achievements and for this u get BAN
