Delta is a browser hijacker, which is promoted via other free downloads, and once installed it will add the Delta Toolbar, and change your browser homepage and default search engine to

Delta Search will display advertisements and sponsored links in your search results, and may collect search terms from your search queries. The Delta infection is used to boost advertising revenue, as in the use of blackhat SEO, to inflate a site’s page ranking in search results.

Delta it’s technically not a virus, but it does exhibit plenty of malicious traits, such as rootkit capabilities to hook deep into the operating system, browser hijacking, and in general just interfering with the user experience. The industry generally refers to it as a “PUP,” or potentially unwanted program.

Delta Search got on your computer after you have installed a freeware software (video recording/streaming, download-managers or PDF creators) that had bundled into their installation this browser hijacker. This browser hijacker is also bundled within the custom installer on many download sites (examples: NET, Brothersoft or Softonic), so if you have downloaded a software from these websites, chances are that Delta was installed during the software setup process.

For example, when you install MixiDJ, you will also agree to change your default browser homepage and default search engine to, and install the Delta Toolbar.

However when you uninstall MixiDJ from your computer, your web browser’s default settings will not be restored. This means that you’ll have to remove Delta Toolbar and from your favorite web browser manually.

You should always pay attention when installing software because often, a software installer includes optional installs, such as this Delta Search. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.

    Hello Elliot,
    Can you please run a scan with Combofix and post the logs here so that I can get an idea on what’s going on:

    You can download ComboFix from here:

    VERY IMPORTANT !!! Save as Combo-Fix.exe during the download.ComboFix must be renamed before you download to your Desktop

    Close any open browsers.

    Very Important!!!> Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause “unpredictable results”.

    WARNING: Combofix will disconnect your machine from the Internet as soon as it starts

    Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.

    If there is no internet connection after running Combofix, then restart your computer to restore back your connection.

    1. Double click on ComboFix.exe & follow the prompts.

    2. Accept the disclaimer and allow to update if it asks

    3. When finished, it shall produce a log for you.


    Do not mouse-click Combofix’s window while it is running. That may cause it to stall.

    Do not “re-run” Combofix. If you have a problem, reply back for further instructions.

    If after the reboot you get errors about programs being marked for deletion then reboot, that will cure it.

    Please post the Combofix, so that I can get an idea on what’s going on.
    Next, please run a scan with HitmanPro and Malwarebytes, then let me know how is your computer running.

  • Stelian Pilici

  • Jeremy Bloom

    Awesome, it is great that there are enough of the good guys out there to counteract the villains trying to jam up our machines with rubbish and worse. Thank you. I wish the others didn’t exist. I can’t fathom why people would dedicate their lives to causing problems for others. Is there even any money in it? Who would do this, and why are these companies legal?

  • jenni

    removed everything, make sure you do all 5 steps as i left the 4th scanner for 10 minutes and nearly aborted as it didnt find anything, but then it found lots of threats and hitman pro found over 1,000! all gone now, thank you

  • Angelique Jurd

    Thank you. I had removed everything from my programs, I had changed the extensions and defaults in Chrome – and it was still damned well there. Finally it is gone. THANK YOU>

  • CK10

    Thank you for your help – life saver!! Vamos Barca!

  • Stelian Pilici

    This is a false positive. JRT uses advanced cleaning techniques, so some antivirus engine due detect this utility as malware, nevertheless its 100% clean and safe to use.

    Stay safe!

  • Chris L

    Thank you very much. This seems to have done the trick. One last step is to reset your homepage or google chrome startup page list by removing the link to delta search. Other than that very nice article and very helpful.

  • Bandz

    20 mins later my computer is running faster and i got all the bs off #TYBG

  • Jeffrey McIntosh

    Thank you very much for this follow through of how to get rid of Delta Search!

    I got this yesterday night and I started to deal with the ‘Delta Search-problem’ about >AN HOUR< ago (it will be faster for someone else since I am generally pretty slow) and now it's gone. completely GONE.
    It was in fact already deleted after I completed Stage 3. The scan with Malwarebytes Anti-Malware Free didn't find anything and nor did Hitman Pro find any malware, but you should of course not skip them.

    I am thankful for finding out about this solution and if I there's anyone having a problem with Delta Search I'll recommend this guide!
