Delta Search Virus - How to remove?


Delta Search virus is a malicious program that causes redirects to a sub-domain on website. The program is categorized as a browser hijacker as it seeks to boost traffic to a specific website by force (without full consent) and get profit this way. Delta search makers get money for clicks on advertisements in their search results. This malware gets into computer systems after installing some free programs that are bundled with adware and hijackers.  Typically, Delta Search virus or related toolbar is used for IE and plugin or extension for other browsers. There are no visual toolbar on Firefox and Chrome except search engine change thus it is harder to track down. The fact that there is no useful function but searches are hijacked is one more proof that Delta search is very malicious software.  It is possible that it is distributed with trojans as well.

Delta Search virus changes the settings of your browser, which include default search page, homepage, some Internet settings alterations and so on. As such, all search traffic is re-routed through their homepage, which might collect information about things you look for. As you are not given the choice to use different search engine, this is not a thing to be taken lightly. Additionally, Delta Search virus will install programs that freeze browser settings and revert them back after each restart. This is done to prevent the “uninstall” instructions they provide on their website from being useful.

Delta Search is supported by ads. Thus you can be rerouted to some other websites that contain malware infections. Quite easily they can also be installed to your computer. Typically, search hijacks are accompanied by rogue registry cleaners and common browser adware, that display even more advertisements.

Our research shows, that Delta Search was using name Claro Search previously. This is well – known hijacker on its own, though replaced with Delta for now. Additionally, there are couple well-known versions (hosted on separate subdomains): Mixi DJ and VisualBee. These toolbar versions are promoted using their own names, but use the same engine, same dirty tricks and are basically the same.

You are highly advised to remove Delta Search Virus from your computer immediately after noticing it on your computer. Do not hesitate and run a full system scan using a reputable antispyware tool, for example Spyhunter. Don’t forget to change your search provider manually to the one you prefer. If you want to remove the hijacker yourself, here are manual instructions :

Special Delta Search removal instructions

First, you will have to remove Delta Search and related programs from control panel  and browser plugins. In control panel I recommend uninstalling ALL programs installed on the same date as problems have appeared. Some versions of this virus installs software that block browser settings from changing. Such program is called Browser Protect, Sprotect or similar. To identify these, scan with Spyhunter might be useful.  You can use other anti-adware programs as well.

After Browser settings freezer is uninstalled, you can uninstall the extensions and revert Delta search virus infected settings in your browsers.

How To remove Delta Search virus from Internet Explorer:

  1. Click arrow on the right of search box
  2. Do following: On IE8-9 choose Manage Search providers, On ie7 click change search defaults
  3. Remove the from the list

How To remove Delta Search from Firefox :

  1. Enter “about:config” in url bar. This will open settings page
  2. Type “Keyword.url” in the search box. Right click it & reset it.
  3. Type “” in the search box. Right click it & reset it.
  4. Type “” in the search box. Right click it & reset it.
  5. Type “browser.startup.homepage” in the search box. Right click it and reset it.
  6. Search for ‘browser.newtab.url’. Right-click and reset. This will make sure that the search page won’t launch on each new tab.
  7. If the settings revert and scan with anti-malware programs are clean: Close firefox, open file explorer and enter %AppData% in the address bar. enter user.js in search box. If this file exists, rename it and start firefox again. You will have to repeat the steps above.

How To remove Delta Search from Google Chrome:

  1. Click 3 horizontal lines icon on browser toolbar
  2. Select Settings
  3. Select Basics ->Manage Search engines
  4. Remove unnecessary search engines from list
  5. Go back to settings. On Startup choose open blank page ( you can remove undesired pages from the set pages link too).
  6. If your New Tab page is hijacked, you will have to scan with anti-malware program or use New Tab Redirect extension from Chrome Store.

Remove shortcut hijack (all browsers) (optional):

If your browser opens Delta Search page on startup only, try this:

  1. Right click on your browser icon. Choose Properties;
  2. Open Short cut tab;
  3. Delete Delta Search part from target field.

Note, that you might have to scan with anti-malware programs if the Delta Search problem continues – we can not rule out that the toolbar is installed with help of malware. For such cases, repeat scan with Spyhunter, Hitman Pro or use Adwcleaner.

      monz: Rescan with Spyhunter and hitman pro : . It might be an trojan that resets browser settings to malicious ones. Also, uninstall everything installed during last days from control panel (sort by date)

    It’s still there, even after I uninstalled everything!

      Ellie: If you uninstall everything, go through manual removal instructions again ( or use adwcleaner / antimalware program)

    Didn’t work. This is driving me crazy 🙁

      Santi: Use anti-malware programs in such cases, maybe there is a trojan.

    Thanks!!! I’ve been trying to figure this out for several hours now, you’re a life saver =)

  6. Brad Powell

    Thank you so very much. I’ve gone to several other sites and tried the options they suggested (short of buying any product), but nothing helped. What you suggested worked like a charm. Thank you, thank you, thank you.

    I try to run Spyhunter but it comes up witha message say that the destination is not a valid Win32 application. Help anyone? I’ve followed all the manual steps and uninstall/ deleted.

    *Delta infected my computor after I downloaded VLC media played

  8. Evelyn

    Delta Search is getting worse. I was infected with Delta Search, apparently when I downloaded Shockwave Flash. I ran Spyhunter, MalWareBytes, and Microsoft’s spyware programs (and all my virus scanners) and none were able to detect it. It’s now somehow developed the ability to make it impossible to remove it from the “Manage Search Engines” list in Google Chrome (there’s no “x” to click on. It prevents any search using the term “Delta Search”. If you change the default engine, it changes it back.

    I have a question. I went to “uninstall programs” and was able to uninstall Delta Search, but in order to remove Delta Chrome Toolbar, I get a message that says I have to use Delta’s uninstaller, and do I know and trust it? Of course I don’t trust it. What should I do?

    BTW I’m running Windows Vista. I did a system restore and uninstalled and reinstalled Chrome, and so far I’m able to use the web again…

      You can try using Delta Search uninstaller, but in my opinion all these are form of scam : if you uninstall DS from control panel, they should remove their search settings automatically too. And Delta search fails to do so. So, how one can trust that it will remove everything?
      I would run Spyhunter or Adwcleaner. Mbam does not specializes in such threats.

  9. Evelyn

    Thanks, Giedrius. I made a mistake in what I wrote to you. I should have written “Delta installer”. I’ll try to explain more clearly what I mean.

    I’m running Windows 7. When I go to my computer’s control panel and click on “Uninstall or change a program”, one of the programs listed is “Delta Chrome Toolbar” and the publisher is “Delta Installer”.

    I clicked on the program “Delta Chrome Toolbar” and “Uninstall” and got this message from my computer:

    “An unidentified program wants access to your computer. Don’t run the program unless you know where it’s from or you’ve used it before.”

    When I click on “Details”, I see the following:

    “Unidentified Publisher Update 1.0.0. Deltainstaller”

    Then I have two choices:

    -Cancel. I don’t know where this program is from or what it’s for.

    -Allow. I trust this program. I know where it’s from or I’ve used it before.

    Since I don’t trust the program, I can’t click on “Allow”. But if I click “Cancel”, the program doesn’t get removed.

    1. Giedrius Majauskas (admin)
      Post author

      Evelyn : Click allow, it will not be able to launch if you click cancel. Later on scan with anti-malware programs for leftovers.

  10. Evelyn

    Also-I ran both Spyhunter and now Adwcleaner. Neither one detected Delta Search on my computer.

  11. Evelyn

    That’s my question…how do I know if it’s safe to click “Allow”? Can you explain? I’m afraid that clicking “allow” might unleash even more bad stuff into my computer.

    1. Giedrius Majauskas (admin)
      Post author

      Evelyn : The installer and delta search is on your PC already. So, theoretically, very malicious programs would be able to download other software anyway. You can use anti-malware programs, but as you see, there are multiple versions of delta search, some of which are not detected. The problem is the settings, as many of program uninstallers leave search settings behind, which is not what one wants.

  12. Debb

    about:config was the ONLY thing that worked for me even after uninstalling, THANKS!

  13. Debb

    I should have said about:config and the next 4 steps….they had it in the tabbing….

  14. zawzaw

    that so useful for me. thanks

  15. vishal Joshi

    Thanks very useful to removed delta search..

  16. Lewis

    Hey, how do you know once you got it removed?

  17. JaneF

    Thank you so much, this has been driving me mad for a week. Went into the config and reset what you siad, but on looking through the config setting for browser and various other things saw that it was there too and ended up resetting about 10 items in the config. Now I am back to the Firefox defaults and I can set up my home page properly and search so much better. I think it came in with the Firefox 19 update which I ran last week- other than that I have not been updating anything lately and that’s when it started, so a warning to users of Firefox!

  18. JV

    Personally I think my entire computer is a big virus. All websites and electronic transaction methods are designed to track and log what internet sites, products or services the user sees, uses or buys.

  19. aatif

    my pc hs been affected by delta search.. i used spyware and it got detected but then it tells to register and pay in order to remove delta search and all threats.. i dont want to pay.. when i try to uninstall delta search toolbar and dealplay from control panel-programs and features it gives a message as..” you are unable to access contact your system administrator”.. please help me to set my firefox and IE back..

  20. monkey_d_luffy

    thank you very much i tried deleting all the crap that had delta in it but couldnt get rid of it this did the trick tyvm

  21. Derrick

    Evelyn, I hear what you are saying. I use three browsers chrome,firefox and IE I took care of IE and firefox but I had to delete chrome. This was my solution after doing any and everything I could think of. With IE I only had to go into the settings it worked immediately and with firefox I had to manually reset everything to defaults. I hope this helps you.

  22. Stella

    I use firefox and can’t install Spyhunter, ADWcleaner or Roguekiller. My AVG scanner stops them, yet lets delta search go through. I did get the browserprotect.dll in the allusers files with hitmanpro, but it still hijacks my firefox browser.

    So how do I manually reset it?

    1. Giedrius Majauskas (admin)
      Post author

      Stella: Read instructions above. Uninstall everything you got in the last days from control panel. Rogue Killer does not help against hijackers that much 🙂

  23. Dutch

    Many thanx! I really needed to get rid of this!

  24. Stella


    Okay, after a few scan runs, I finally got Spyhunter to send its bots through my entire system and it uncovered a host of nasty components to DeltaSearch. Some of them were in my Documents and Settings file in various places including under Firefox, some were in my program files, and quite a few were in my registry. So I took an afternoon to write them down manually, and comb through each directory and remove them one by one.

    The only one I couldn’t delete was under the IE: start page data in my registries. Whenever I would try to delete it, it would just replicate itself and pop up again. I don’t use Internet Explorer, so this doesn’t bother me, except that it’s still around, which means somewhere in my computer, some of its tentacles are still lurking — but I did as you suggested and changed the browser settings. So now I have no home page at all, either in IE or Firefox. But at least DeltaSearch isn’t hijacking it. So, thank you for all the advice. It’s been very helpful.

    (I also managed to get rid of Conduit and Conduit Engine and the Data Manager Trojan through this process, so I owe you a quadruple thank you.)

      Stella : during install of Spyhunter, you are asked if you want to protect or reset your home page settings. Double check under spyhunter settings which page you have set up there and if you use that option.
      Under some cases it is impossible to tell if the user picked the start page himself or if it was hijacker, maybe it is just a simple issue.

  25. l

    Thank you so much, the resetting the new tab is sooooooooooooo helpful, you are wonderful for putting this out there, it was easy peasy. Good karma!!!

  26. Harpreet Kaur

    Thank you for the help listed above. It helped after trying so many troubleshooters available all over the web. this finally proved successful. 🙂

    Actually delta search is disturbing me it automatically add in my firefox bullshit

  34. Michaelle

    I just realized that I have been invaded by delta search; the first thing I noticed was that some of my links in one of my favorite toolbar folders are missing, then I noticed the delta search icon. I am going to try the manual removal first. I was very put off by the video; it seemed to encourage me to accept IE as my browser and said I had chosen things that I had not; I find the video confusing; also how can one know if the anti malware companies do not conspire in the malware to begin with?

    1. Giedrius Majauskas (admin)
      Post author

      Michaelle: I do not recommend setting IE as main browser, sadly many still use it, so we started removal instructions from IE. If IE is not infected or you do not use it, skip that part.

      Install Spyhunter in normal mode. This error happens if you install it in safe mode with networking.

    Hi there,

    I’m using IE10 and I follow via your Special Delta Search removal instructions

      You will need administrator account or use uninstaller tools like RevoUninstaller. You can also try scanning with other programs, like Adwcleaner or malwarebytes. Some are free or free to try.

  42. emma

    thank you very much, it really works!

  43. Chris

    Thanks! this was driving me crazy, couldn’t get it completely removed from FF until I found this. the about:config resets finally got it off.

    Makes me wonder why i should keep buying expensive anti-virus programs that can’t even pick this up :-/

    1. Giedrius Majauskas (admin)
      Post author

      Chris: AVs might remove some of components that reset the settings again to delta, so they are not completely useless in these cases.

  44. aaron

    I ran the scan it said I have 256 threats! when I clicked ‘fix’ it says that I have to buy the full version for it to remove the threats. Please help, I start university this month :O

      Aaron: Try uninstalling the programs detected (except cookies) and then follow manual guide. It is just simpler with using automated programs.

  45. Ron Groot

    Thanks so very Much I was getting insane of this delta search, so aggressive as they are. But now due to these steps described here i am free from it AFTER 4 MONTHS

      Actually, they are from separate IP addresses. Also, for manual removal SH is desired (to identify browser protection module used) but not necessary.

  48. Jeremy

    Ding dong the witch is dead, the wicked witch is dead!…. finally. After scans and manual removals everywhere else the New Tab was still being hijacked. Back to normal now. Thank you!


  49. Shannon Middleton

    This wasn’t very helpful. I am currently using chrome, and the delta search never shows on manage search engines. Also, it is set to open on the new tab page, and it does and simply changes to the Delta search engine. Is there any other way to get rid of it as it slows my laptop down significantly and is extremely irritating.

    1. Giedrius Majauskas (admin)
      Post author

      There are specific versions of delta search that use hidden new tab setting. If this is on new tab (on startup settings are easily editable) you got 2 options.
      1. Scan with Adwcleaner, Spyhunter, Malwarebytes, etc – they might find and reset this setting
      2. Install new tab redirect Chrome extension (search the chrome extension store) and change it google or smth.

  50. EDZ

    THANK YOU SO MUCH! I REALLY HATE THAT DELTA-SEARCH and HOME. I dont even know, it automatically installed on my PC.
