"Congratulations, You Have Won" hijacked!

Recommended Posts

I seem to have fallen victim to a browser hijacker, one that opens new tabs to a "Congratulations, You Have Won" page, saying I have possible won an iPhone, etc. I can't get rid of it. Malwarebytes doesn't find it, nor MS Defender, nor adwcleaner. I found a few pages that want you to download a (suspicious) tool called 'Reimage', a page Malwarebytes Premium (the version I have) blocks -- and probably, rightly so. Both IE and Chrome appear to be affected.

Hi meimeiriver2 :)

My name is Aura and I'll be assisting you with your malware issue. Since we'll be working together, you can call me Aura or Yoan, which is my real name, it's up to you! Now that we've broke the ice, I'll just ask you a few things during the time we'll be working together to clean your system and get it back to an operational state.

  • As you'll notice, the logs we are asking for here are quite lenghty, so it's normal for me to not reply exactly after you post them. This is because I need some time to analyse them and then act accordingly. However, I'll always reply within 24 hours, 48 hours at most if something unexpected happens
  • As long as I'm assisting you on Malwarebytes Forums, in this thread, I'll ask you to not seek assistance anywhere else for any issue related to the system we are working on. If you have an issue, question, etc. about your computer, please ask it in this thread and I'll assist you
  • The same principle applies to any modifications you make to your system, I would like you to ask me before you do any manipulations that aren't in the instructions I posted. This is to ensure that we are operating in sync and I know exactly what's happening on your system
  • If you aren't sure about an instruction I'm giving you, ask me about it. This is to ensure that the clean-up process goes without any issue. I'll answer you and even give you more precise instructions/explanations if you need. There's no shame in asking questions here, better be safe than sorry!
  • If you don't reply to your thread within 3 days, I'll bump this thread to let you know that I'm waiting for you. If you don't reply after 5 days, it'll be closed. If you return after that period, you can send me a PM to get it unlocked and we'll continue where we left off;
  • Since malware can work quickly, we want to get rid of them as fast as we can, before they make unknown changes to the system. This being said, I would appreciate if you could reply to this thread within 24 hours of me posting. This way, we'll have a good clean-up rhythm and the chances of complications will be reduced
  • I'm against any form of pirated, illegal and counterfeit software and material. So if you have any installed on your system, I'll ask you to uninstall them right now. You don't have to tell me if you indeed had some or not, I'll give you the benefit of the doubt. Plus, this would be against Malwarebytes Forums's rules
  • In the end, you are the one asking for assistance here. So if you wish to go a different way during the clean-up, like format and reinstall Windows, you are free to do so. I would appreciate you to let me know about it first, and if you need, I can also assist you in the process
  • I would appreciate if you were to stay with me until the end, which means, until I declare your system clean. Just because your system isn't behaving weirdly anymore, or is running better than before, it doesn't mean that the infection is completely gone
    This being said, I have a full time job so sometimes it'll take longer for me to reply to you. Don't worry, you'll be my first priority as soon as I get home and have time to look at your thread


This being said, it's time to clean-up some malware, so let's get started, shall we? :)

Do you still need assistance with this issue?

Yes, the issue still persists. Even though Malwarebytes now identifies and blocks the typical 'youwinner' URL's since a few days, it hasn't been able to find the malware itself, though.

These 'youwinner' URL's don't pop up often, btw (mostly when I first start up my system), but even once, is once too many.

Just to be sure, these only occurs when you're using Internet Explorer and Google Chrome, right? Not when these programs aren't running.

Exactly. They're browser hijacks/redirects of an open tab, that suddenly gets changed to a malware site URL (and, like I said, Malwarebytes blocks these URL's now, but can't find anything fishy on my system).

Alright, can you install uBlock Origin for Chrome, and let me know if these redirects still occurs?

Installed. But I hope we can find a solution too (as in removal of the malware), as blocking the URL's is something Malwarebytes already does as well.

P.S. Haven't seen these hijack URL's in 2 days, btw (or Malwarebytes reports of them being blocked). But, then again, I haven't seen Malwarebytes (or Windows Defender, for that matter) report they removed anything, either.

P.S. I forgot to mention this, but when it happens, it's always the far-right open tab that gets its URL changed; nothing in the middle or earlier.

I don't think that you are infected. I think that, because you're not using any adblocker in either Internet Explorer or Google Chrome, you are being hit by malvertising. uBlock Origin is a content blocker, and it also block ads and code that tries to load them. So installing it should prevent these from happening.

You may very well be right! :) That ublock progam is a godsent, btw! You wouldn't believe the unsavory URL's I already see it blocking. The site where this occurs on (a game forum I frequent a lot) has many ads being shown. It probably really *is* that site! It's a legit forum; but, like you say, malvertising could still be taking place on it.

I already thank you kindly for your assistence! *Keeping fingers crossed*.

At this point, feel free to close this case. I'm pretty sure it was the malvertising.
