I've lost everything

Now why would you download something that pops up on a website.

But you haven't lost your hope.

Why did you download something from a random popup?!?

Why the hell would you even open that?

And then people wonder they got hacked. I rest my case.

Is your email id also been compromised?? If not then do you still have the purchase receipt of the games. If you have those then I don't think you will have any problem in recovering your account. Maybe write a ticket to the support stating your problem and attach all the proofs you have.

madness, i am disappoint

Shit happens, but it's too early to start freaking out, don't you think? You haven't even heard from support yet. Plus, you mentioned that your inventory got cleared out, so even if you lost access to those virtual receipts, you can still report this sudden "unusual" behavior and say that it's not consistent with your behavior (from when you still had access to your account), and maybe support will buy it, who knows. They can be pretty reasonable.

At least you're not dead.

Good luck getting the account back :-/.

I’m sorry this happened to you friend. I recommend you to report this immediately to steam support, explaining on you ticket how this Trojan hacked your account.

May be Valve can recover your items if you report it fast, detailing actions of this malicious software on your account, and prevent the community to be affected by these odious crackers too.

This is the link to make your ticket to report your problem: https://support.steampowered.com/

I wish you Good luck.

Dude...

If you have any credit card info linked (or discussed in your email (OR if your email and password are also your name on, say, PayPal), I'd get busy changing all that stuff too :| If my main email got hacked away from me I'd be in a bit of trouble :> EVERYTHING is linked there: my bank, my disability, PayPal/Amazon/Ebay/GOG/GamersGate/ShinyLoot/Google, about fifty forums, my address book which contains ancient addresses from old friends I wouldn't be able to get back, saved emails with passwords and download keys for stuff like BMT Micro.. Tons of stuff :> At some points I'm scared to even click the X on pop-ups to "close" them.. Easy enough to disguise a "DOWNLOAD THE DEVIL!" button to look like an X and stick it in the upper right..

If this was a pop-up from SteamTrades, well, seems like they should do something about that ASAP :| Very misleading stuff..

ANYWAY! Steam should be able to tell you've been robbed, by the IP address changing, the emptying of the inventory, changing of personal details, and, of course, your filed support ticket.. All-together that piles up into a pretty good chunk of evidence there :| Maybe if you're really lucky they'll have some previous offenses already on file concerning the new IP that's using your account now, too..

Gibaway plz

Steamtrade.com?
The real site is steamtrades.com

RIP Sweet Princess </3

Actually, I think you are able to get your stuff back. My friend was hacked once so he lost all his stuff. He messaged steam support and got his stuff back :)

Gosh, good luck! and never download anything like that without doing a research about it first. Even better, don't even do research about it unless it becomes popular and everyone talks about it :D
Once again, good luck! Also, it might take Valve a week or two to reply to you.

it's a lesson for you my son

Hey, even if the wind is rising, you must try to live.

That was stupid.

First of all: be sure to contact you bank and/or other service if you have stored information required for purchase in your account and/or e-mail (if lost). Changing passwords and e-mails for accounts linked to lost e-mail (if you lost it too) is advised as well. Better safe than sorry.

Good luck with getting your account back fast. If you have connected/linked your Steam account to some other services and/or you remember your first e-mail and/or you have some billing details for your account, getting it back shouldn't be hard - just visit Steam Support and make your ticket to report this issue. As for e-mails for Valve, I think in response they will ask you to visit support.
Be sure to contact your e-mail provider as well, detailing the problem. If you have some extra securities enabled / informations stored there, it's quite possible you can get it back too.
As for items - in many situations support was getting items back to owner after undoing transactions made so you might be safe.

Few tips or future reference:

• don't disable Steam Guard... it's annoying but saves from many problems - assuming other person controls your account, I assume you disabled SteamGuard or your e-mail account was also taken over (if so, be sure to change e-mails and passwords for other accounts!);
• Valve/Steam services (and others) won't ask you to download anything other than Steam application;
• commercial applications should be signed (RMB->Properties?);
• if you are not sure of some application, don't run it in system - for unknown applications i's better to have extra environment like virtual machine, dual boot or something similar, because it's quite easy to read most of passwords once you have application running on computer (Chrome, Opera, Firefox, Firefox and many others - safe applications used for password recovery... recovery and stealing data use same methods but for different purpose);
• before downloading any unknown application, be sure to check URL from which you have downloaded it (download manager?);
• same rule as above but for e-mails - always check sender and instead of using password reset links provided (unless you asked for those), simply open web page and navigate to proper form;
• never use important accounts on unknown computers and in public (or unknown) networks on not encrypted connections (use https only on those);
• watch out for scam sites... easiest way is to use sites known to you and bookmarking them;
• and most basic password rules:
  • try not to store passwords unless it's necessary or safe (encrypt them?),
  • use few passwords for different accounts,
  • change passwords from time to time (rotate?),
  • never provide password for one web page other other web page (domains);
  • for very important accounts use strong passwords and remember to provide some extra ways to login (phone number, other -mail, linked accounts?);
• AV scanner... well, for new threats are usually not detected by them for few days and sometimes even weeks... even paid ones - storing unknown file for couple of days and/or sending it to VirusTotal (it's using many different AV scanners to determine whether file is threat or not) might be wise.

Sorry for lecture - I know it's easy to say after problem but well... with those (almost) no one would have many problems like those :P

Well, once again, good luck in getting your account, items and e-mail back fast and see you around!

Unfortunately you don't appear to have lost your stupidity.
