Firefox hijacked

In the past two days my firefox browser has been hijacked.  As for operating system and software, I have Windows 10, Bitdefender 2015 Total Security, Malwarebytes, and Malwarebytes Anti-Exploit.  Here is what happens;  I open Firefox browser, I see the MSN homepage, but in seconds the homepage disappears and I see an advertisement (top left of my screen) that is for a high speed Internet service from AT&T.  The size of this advertisement comes in two forms.  First, it can either be a larger or smaller advertisement, both being in the same location (top left).  What happens, is when I see this, I click on the homepage icon within Firefox, the page reloads and then I see a different sized (same) advertisement. 

 

If I were to click on a link that takes me to a news article or otherwise, this advertisement will still continue to take over the browser.  Recently I downloaded Adware Removal and also Hitman Pro in hopes of removing this hack or whatever it is.  No luck.  I have attached a screenshot of one of these advertisements.  I erased my favorites bar, which will make it look funny, but I didn't wish to share personal information.

 

I have contacted Firefox about it, but no response thus far.  After researching Google on another browser, it seems that Firefox was hacked earlier.  Not sure if this was in the past 2-3 days, or whether it was much sooner.  Also don't know if this would actually apply to my issue presently.  Another search showed that hackers will use this method to exploit their Pay per click campaigns, hoping you will click which makes them money. 

 

One more note, when I first began to see this annoyance, I noticed that Malwarebytes database was continually updating, as referenced by the system tray notification.  Also Malwarebytes Anti-Exploit Premium would show that it was blocking various items, but again, this still continues.  Can someone here help?  I am worried about buying anything over the Internet, using banking, or anything right now.  Thanks

Hello,

    

 

They call me TwinHeadedEagle around here, and I'll try to help your with your issue.

 

     

    

Before we start please read and note the following:

  • We're primarily oriented on malware removal here, so you must know that some issues just cannot be solved and you must be prepared for this. Some tools we use here will remove your browser search history, so backup your important links and all the files whose loss is unacceptable.
  • Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
  • Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time. Keep in mind that private life gets in the way too. Note that we may live in totally different time zones, what may cause some delays between answers.
  • Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
  • Do not paste the logs in your posts, attachments make my work easier. There is a More reply options button, that gives you Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
  • Always execute my instructions in given order. If for some reason you cannot completely follow one instruction, inform me about that.
  • Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.
:excl: I can't foresee everything, so if anything not covered in my instructions happens, please stop and inform me!

:excl: There are no silly questions. Never be afraid to ask if in doubt!

Please download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatibale with your system. If you are not sure which version applies to your system download both of them and try to run them.

Only one of them will run on your system, that will be the right version.

  • Double-click to run it. When the tool opens click Yes to disclaimer.
  • Press Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

Yes, only Firefox.  So far today, I have not seen this on Firefox.  Very odd.  Between Bitdefender, Malwarebytes, Adware Remover, Hit Man Pro, nothing was ever found.  When this happened earlier, I would clear everything (cache, browsing history, etc.), and I would disable all add-ons, start in safe mode, and it would still take over my browser.  But like I said, today it is not happening.  Do you think I was being hacked?  Or would it be from Firefox server?  It is way too obvious that someone was using my web interface to show me their AT&T advertisement.
