Firefox Homepage Hijacked by Claro-Search

Hello, I can recently acquired the Search Engine Malware? (I think it is a Malware)

I can not for the life of me take back the "HOMEPAGE" I have searched around everywhere and found how to take over the "NEW TAB" issue and it is back to

But I have yet to find a single issue with the Homepage being automatically hijacked and sending me straight back to the website no matter what I do to change the URL.

I have done the following things.

1: Removed the Toolbar from Add-ons

2: Removed the Toolbar from Control Panel

3: Shut down my computer and rebooted into Safe Mode - Networking to run Malware and other virus scanners.

4: Changed my Hosts File

5: Turned on Firefox in Safe-Mode resetting all defaults.

6: Changed the URL several times. ____________________________________________________

I can set the homepage to "Blank" which solves the issue. BUT I want Claro off my computer for good not just covered up with settings.

NOTE: I do not have expert knowledge in computerized configuration so I am at a lose into doing something like Manually checking my systems files and such to remove this issue.

If you know how to fix this, Please be detailed and simple.

Also! If i type anything into the search bar incorrectly it automatically uses iSearch-Claro to search for results.

Is that the search bar on the about:home page?

If there is a problem with searching via the default about:home page then try to reset the search engine used on the about:home page.

Reset the browser.startup.homepage_override.mstone pref via the right-click context menu to the default on the about:config page and close and restart Firefox to restore the about:home page to its default.

  1. Open the about:config page via the location bar
  2. Type in the Filter bar: mstone
  3. Right-click the browser.startup.homepage_override.mstone line and select: Reset
  4. Close and restart Firefox

If this didn't help then delete the delete the chromeappsstore.sqlite file in the Firefox Profile Folder and repeat the above.

You can use this button to go to the Firefox profile folder:

Just open the webpage you need to be as your homepage, Bookmark it.

Now, go to Mozilla tools>>> Setting>>> in the homepage section click on Use Bookmarks>>. Choose your Page from the list. Apply & OK.

Restart the browser. Done!!


U will never see the Claro search anymore. :-)

Just share my experience:

As of 11/19/2012.

This virus varies from time to time. Above posts are no longer useful. I was not able to find any effective way by searching online. It took me a whole day to figure it out.

Both in your registry and hard drive, search the following:

claro, browsermngr, (another thing I forgot)

Delete them and their possible containers. Everything will be fine. Most files won't be able to be deleted directly. You either need to do it in safe mode, or remove them from service and then reboot to continue.

I haver tried a lot of things and finally I HAVE SUCCEED.

I have:

1. Uninstalled the Claro LTD Toolbar software from Windows and any other Claro or Babylon software.

2. Cleaned Extensions, etc.

3. Cleaned the about:config

4. Reset search engine settings.

But claro search engine kept on appearing as a home page.

What I think it has been the killer move has been to remove the "Browser Manager" process (browsemngr.exe), following this, with a little variation:

The variations are:

1. Run the cmd as administrator. If not the command will not be able the delete the service (sc delete "browser manager" will not work).

2. To finally Remove the Browser Manager folder you might need to restart in safe mode.

I hope this helps :-) because it was a really annoying and interfering malware.

(The same overall process worked with Chrome, as long as its homepage had also been hickjaked by the same malware.)

I have not tried using Malware Bytes, maybe it works.

Thanks for this. I have tried all other help ideas without success. This one works by Uninstalling Browser Manager in Control Panel as well as removing the Caro search in manage search engines in the top right of the screen and restoring default preffered home page in File, Options, homepage settings. thanks

Just started using Firefox and downloaded Version 18 and since I haven't used Firefox for some time I was very surprise to find some problems still exist; for one is the crazy Claro Search Toolbar and Search Page, so after following All attempts that are listed and appear easy-they didn't work for me, the last resort I used the Program AdwCleaner-And it worked-so far?- the following is the listing from this program;

The Claro solution changes the homepage only. When I opened a new blank tab I still got the Claro search page, rather than the Firefox page that shows thumbnails of recently opened pages. It was much more complicated getting rid of that. I don't think they know what they're doing.

Yes, of course I looked at the Claro page. As I already mentioned, all that pages does is tell the user how to reset the homepage. Reading all of the messages in this forum should make it abundantly clear that the problem is much greater than that. The homepage will not stay reset, and a new tab will not come up with thumbnails of recent pages, but instead opens onto Claro Search. This has been stated many times, but I'll try it again: RESETTING THE HOMEPAGE IS NOT A SOLUTION. I have fixed my problem, using various techniques described in this forum, including cleaning out a Firefox data page and uninstalling a Claro program that I don't recall ever installing. This is a serious problem that demands more serious attention from Claro.
