Many computer users got infected with Smartsearch Browser Hijack, and they complained that they have no clue on how to remove it from the compromised computer. I hope that the removal steps below would work:
Step 1: Remove add-ons and Extensions from infected browsers.
Internet Explorer:
Start Internet Explorer.
Click on setting icon at the upper right and select Manage add-ons.
Click Toolbars and Extensions on the left side, search for and remove any suspicious add-ons.
Mozilla Firefox:
Run Firefox browser.
Click on Tools and select Add-ons.
Click Extensions on the left side, find out and disable any suspicious add-ons.
Google Chrome:
Run Google Chrome.
Click on wrench icon at the upper right corner, click on Tools and select Extensions option.
Find out the malicious add-ons and remove them from Chrome.
Step 2: End relevant processes
Press Ctrl+Alt+Del or Ctrl+Shift+Esc keys together to open Widows Task Manager. While Widows Task Manager opens, click on Processes tab. Select the related processes and click End Process button to cease them.
Step 3: Show Hidden Files and folders
Click Start menu and Control Panel from the list. Click Appearance and Personalization link, and then double-click Folder Options.
In the Folder Option, click its View tab. Check Show hidden files and folders and uncheck Hide protected operating system files (Recommended) under the Advanced settings, and then hit OK button.
Step 4: Delete registry entries
Attention: Be always to back up registry entries before deleting any of them.
Press Windows+R keys together, while a command box pops up, type “regedit” into the Run box, and then hit OK button to continue.
In the Registry Editor, locate and delete all related registry entries.
Step 5: Find out and remove the following vicious files.
Step 6: Restart your machine

I don't know if you're spamming for the company at the link, but I locked the thread because the previous reply was eleven years ago.
