What is SearchWebAid?

SearchWebAid is a browser hijacker that will change your browser search engine to search.oz4zufv.com. This browser redirect happens because the “SearchWebAid” browser extension or program is installed on your computer.

When installed on a computer, the SearchWebAid browser hijacker will redirect your browser search queries through search.oz4zufv.com, which will redirect to search result pages from search.yahoo.com. This is most likely done to generate advertising revenue by using Yahoo Search for its search results.

SearchWebAid will also open new tabs in the browser that display advertisements trying to sell software, push fake software updates, and tech support scams.

When the SearchWebAid browser hijacker is installed on a computer, common symptoms include:

  • Your web browser’s default search engine is SearchWebAid
  • Your browser’s search queries are redirected through search.oz4zufv.com
  • The “SearchWebAid” browser extension or program is installed on your computer

Why is my browser redirected to SearchWebAid?

Your browser is being redirected to SearchWebAid Search because the “SearchWebAid” extension or program is installed on your computer. This type of program is often offered through advertisements or bundled with other software, leaving the user puzzled where this software came from.

You should always pay attention when installing software because often, a software installer includes optional installs. 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.

To remove the SearchWebAid browser hijacker and check your computer for other malicious programs, please use the free malware removal guide below.

Remove SearchWebAid browser hijacker (Virus Removal Guide)

This malware removal guide may appear overwhelming due to the number of steps and numerous programs that are being used. We have only written it this way to provide clear, detailed, and easy-to-understand instructions that anyone can use to remove malware for free.
Please perform all the steps in the correct order. If you have any questions or doubts at any point, stop and ask for our assistance.

To remove SearchWebAid browser hijacker, follow these steps:

STEP 1: Remove malicious Profiles from your Mac

Profiles are used by IT admins in businesses to control the behavior of their Macs. These profiles can configure a Mac to do many different things, some of which are not otherwise possible.
When it comes to home users, adware and browser hijacker are using the configuration profile to prevent users from removing malicious programs from the computer. This also prevents the user from changing that behavior in the browser’s settings.
In this first step, we will check your computer to see if any configuration profiles are installed. To do this, follow the below steps:

  1. Open “System Preferences”

    From the Apple menu, select System Preferences.

  2. Search for “Profiles”

    When the System Preferences window opens, search for the Profiles icon.
    Search for Profiles in System Preferences

    If there isn’t a Profiles icon, you don’t have any profiles installed, which is normal and you can continue with the next steps.
  3. Remove the malicious profiles

    If there’s a Profile icon, click on it and select any suspicious profile that you want to remove, and then press the – (minus) button. Click Remove to remove the profile.

Remove SearchWebAid browser hijacker from Safari

To remove SearchWebAid browser hijacker from Safari we will check if there are any malicious extensions installed on your browser and what settings have been changed by this malicious program.

  1. Go to Safari’s “Preferences”.

    On the menu bar, click the “Safari” menu and select “Preferences”.
    On the Menu bar Click on Safari then Preference

  2. Check Homepage.

    This will open a new window with your Safari preferences, opened to the “General” tab. Some browser hijackers may change your default homepage, so in the Homepage field make sure it’s a web page you want to use as your start-up page.

    The malicious extension may have a different name on your computer. Look out for any suspicious browser extension that could be behind all the drama – anything you don’t remember downloading or that doesn’t sound like a genuine extension. By default, there are no extensions installed on Safari so it’s safe to remove any extension.

If the above steps didn’t help you remove the SearchWebAid browser hijacker from Safari, you can follow the below steps:

  • Workaround for greyed out Safari’s homepage

    In some cases, after being changed by browser hijackers or malware, Safari’s home page can become stuck (greyed out). You will be able to edit the Homepage field in Safari’s preferences, but the change will not stick. This appears to be a bug, and there is an odd workaround. Try this:

    1. In Safari, choose Preferences from the Safari menu.
    2. In the window that opens, click the General icon (if necessary)
    3. Enter your desired home page in the “Homepage” field, but DO NOT press return!
    4. At the top of the window, click any of the other icons (eg, Tabs, AutoFill, etc).
    5. You may see a prompt asking for confirmation for changing the home page. If so, confirm.
    6. Switch back to the General page and check to make sure the home page has been changed.
  • Delete Safari’s preferences file to remove malicious changes

    Some malicious programs are known to install managed preferences to set the homepage and search engine settings in Safari. If the above options didn’t help you remove the malicious redirects, we’ll need to delete the Safari’s preferences. To do this, follow the below steps:

    1. Quit Safari
    2. Click the desktop to make sure you’re in the Finder, choose “Go” then click on “Go to Folder“.
      Go to Folder mac
    3. Type or copy/paste the following path into the window that opens, then click Go: ~/Library/Preferences/com.apple.Safari.plist
    4. If the file is found, delete it, then re-open Safari

If the above steps didn’t help you remove the SearchWebAid browser hijacker from Chrome, you can follow the below steps:

  • Remove the unwanted policies created by malware from Chrome

    In many cases, changes to Chrome may not be fixed with a simple browser reset. In such a case, it’s very possible that a malicious program has created unwanted policies on your browser. You can check if any unwanted policies are loaded into the browser by typing chrome://policy into the URL bar.
    To reset these policies, follow these steps:

    1. Open a new Terminal window. To do this, go to Finder > Go > Utilities > Terminal
    2. Enter the following commands, pressing enter after each line:
      • defaults write com.google.Chrome HomepageIsNewTabPage -bool false
      • defaults write com.google.Chrome NewTabPageLocation -string “https://www.google.com/”
      • defaults write com.google.Chrome HomepageLocation -string “https://www.google.com/”
      • defaults delete com.google.Chrome DefaultSearchProviderSearchURL
      • defaults delete com.google.Chrome DefaultSearchProviderNewTabURL
      • defaults delete com.google.Chrome DefaultSearchProviderName
      • defaults delete com.google.Chrome ExtensionInstallSources
    3. After running these commands, quit Chrome if you haven’t already done so, then launch it again and check chrome://policy to see if the same keys are still present (you may need to click the “Reload policies” button for changes to show up). If they’re gone, you should be able to change your search engine and home page back to your preferred defaults in Chrome’s settings.
  • Remove the “Managed by your organization” policy from Chrome

    Some malicious programs are known to install managed preferences to set the home page and search engine settings in Chrome. To check for these, do the following:

    1. Quit Chrome
    2. Click the desktop to make sure you’re in the Finder, choose “Go” then click on “Go to Folder“.
      Go to Folder mac
    3. Type or copy/paste the following path into the window that opens, then click Go: /Library/Managed Preferences/
    4. Paste the below path into the window that opens, then click Go:
      Look for the following files, where [username] is your username:

      • com.google.Chrome.plist
      • [username]/com.google.Chrome.plist
      • [username]/complete.plist

      These may be legitimate, so open these files with TextEdit and see if they have links to the troublesome site in them. If they do, delete them and restart Chrome.

  • Uninstall Google Chrome from your computer

    If the above options didn’t help you remove the malicious redirects, it is easier to completely remove Chrome and all data, then reinstall the browser. To do this, click the Finder icon, from the menu bar. Choose Go, and click Go to Folder, then paste one of the below paths into the window that opens.
    You will need to delete all of the below items, but before doing this be aware that this will delete all data for all Google apps you have installed, such as your bookmarks, so you will need to export them before doing this.

    • /Applications/Chrome.app
    • /Library/Application Support/Google/
    • /Library/Google/
    • ~/Library/Application Support/Google/
    • ~/Library/Google/
    • ~/Library/Preferences/com.google.Chrome.plist

    Note: The “~” indicates that it’s the current user’s Library which is often invisible in recent versions of macOS. To get to it you must hold down the Option (sometimes labeled Alt) key down and select Library from the Finder’s Go menu.

    After deleting all of the above files, restart your device. You can now download and re-install Google Chrome on your device. You will need to import any exported bookmarks or other data, and may need to reinstall any other Google apps that you use.

How to Stay Safe Online

Here are 10 basic security tips to help you avoid malware and protect your device:

  1. Use a good antivirus and keep it up-to-date.

    Shield Guide

    It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.

  2. Keep software and operating systems up-to-date.

    updates-guide

    Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

  3. Be careful when installing programs and apps.

    install guide

    Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

  4. Install an ad blocker.

    Ad Blocker

    Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

  5. Be careful what you download.

    Trojan Horse

    A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

  6. Be alert for people trying to trick you.

    warning sign

    Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

  7. Back up your data.

    backup sign

    Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.

  8. Choose strong passwords.

    lock sign

    Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.

  9. Be careful where you click.

    cursor sign

    Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.

  10. Don't use pirated software.

    Shady Guide

    Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.

To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
