If your browser homepage and search engine keep mysteriously changing to Yahoo!, your computer is probably infected with a browser hijacker. While resetting your browser might seem to fix the problem, here’s how to do the job properly.

What Is a Browser Hijacker Virus?

A browser hijacker is probably one of the least aggressive and destructive types of malware, but that doesn’t mean you should allow it to exist on your computer. They are designed to make changes to the infected computer’s browser settings so that advertising or a page that is beneficial to the malware distributor is shown instead of the one you chose.

Because the people who spread this type of virus are somehow benefiting from the change of search engine or homepage, it is unlikely that a hijacker will cause your computer to crash or become inoperable. It can, however, cause performance problems, and can also be a sign that your computer is infected by other malware.

In this case, the virus is probably the “search.yahoo.com redirect virus.” When you open your browser, this virus will redirect you to the Yahoo homepage via an intermediate website. If you click on any of the links on the Yahoo homepage, any revenue from those clicks will be paid to the intermediary website owner.

The Yahoo homepage

It should be noted that this is not the fault of Yahoo, and that search.yahoo.com is a genuine page used by millions of people daily. Yahoo simply sees the intermediary website as a referring site, without knowing that you were redirected through it using nefarious means.

Removing the Yahoo Redirect Virus

First, try to work out how the malware got onto your computer. Browser hijackers are often spread by being bundled up with other software. This could be a free app you installed or a browser extension you have added.

Extensions in the Chrome Web Store

Sometimes the PUA (Potentially Unwanted App) is made obvious during the installation process. You may be asked if you want to also install some supposedly beneficial tool alongside the app you are installing, or may even be asked if you want to let the app change your search engine or homepage. In other cases, the highjacker can be completely hidden and you don’t have the option to reject its installation.

If you have added any new software recently, consider uninstalling it from your computer. At the very least, search online for “name of the software/extension” + “malware” and see if anyone else has experienced the same problems. That will allow you to narrow your list of extensions or software to remove.

The next thing to do is a complete virus scan using reputable and reliable antivirus software. Browser hijackers are not particularly sophisticated viruses and shouldn’t prove too much trouble for a good antivirus scanner to find and remove.

A quick scan will often find browser hijackers, but we would suggest performing a full or complete scan anyway. As browser hijackers are sometimes a sign that your computer has other infections, it is a good idea to let your antivirus software do a full check of your system.

Resetting Your Browser

The final step is to reset your browser settings. This is sometimes said to be the only thing you need to do to fix the problem of your homepage and search engine switching to Yahoo, but it really only treats the symptom and not the cause. Once you’ve removed the virus, find the instructions for your browser below.

Chrome

The Chrome browser settings screen

  1. To reset Chrome, open the browser and click the menu button.
  2. In Settings, expand the Advanced section and click “Reset and Clean Up.”
  3. To be thorough, click “Clean Up Computer” and then click the “Find” button. Follow the instructions if any harmful software is found.
  4. Back in the Reset and Clean Up section, click “Restore Settings to Their Original Defaults.”

Be aware that doing this will disable all of your extensions, clear cookies, and temporary site data, and reset things like Chrome shortcuts. It won’t delete bookmarks, history, or saved passwords.
