What is Fileconvertermaster.com?

Fileconvertermaster.com is a browser hijacker that will change the homepage and default search engine for your web browser to https://tab.fileconvertermaster.com. This browser redirect happens because the “File Converter Master” browser extension or program is installed on your computer.

When installed on a computer, the Fileconvertermaster.com browser hijacker will change the browser homepage to https://tab.fileconvertermaster.com. This browser hijacker will also redirect your browser search queries to https://tab.fileconvertermaster.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.
The Fileconvertermaster.com browser hijacker will also track your searches and display advertisements on Fileconvertermaster.com.

When the Fileconvertermaster.com browser hijacker is installed on a computer, common symptoms include:

  • Your web browser’s default homepage is Fileconvertermaster.com
  • Your browser default search engine is changed to Fileconvertermaster.com
  • Your browser’s search queries are redirected through https://tab.fileconvertermaster.com
  • The File Converter Master browser extension or program is installed on your computer

Why is my browser redirected to Fileconvertermaster.com?

Your browser is being redirected to Fileconvertermaster.com because a browser hijacker is installed on your computer. Often, this type of program is 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 Fileconvertermaster.com browser hijacker and check your computer for other malicious programs, please use the free malware removal guide below.

    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.

Google Chrome

Google Chrome has an option that will reset itself to its default settings. Resetting your browser settings will reset the unwanted changes caused by installing other programs. However, your saved bookmarks and passwords will not be cleared or changed.

  1. Click on the three dots at the top right and click “Settings”.

    Click on Chrome’s main menu button, represented by three dots at the top right corner. Now click on the menu option labeled Settings as shown by the arrow in the picture below, which will open the basic settings screen.

  2. At the bottom, click “Advanced”.

    Chrome’s “Settings” should now be displayed in a new tab or window, depending on your configuration. Next, scroll to the bottom of the page and click on the “Advanced” link (as seen in the below example).
    Click on the Advanced button MacOS

  3. Under the section “Reset,” click “Reset”.

    Chrome’s advanced settings should now be displayed. Scroll down until the “Reset and clean up” section is visible, as shown in the example below. Next, click on the “Reset settings to their original defaults” button.
    Scroll down and click on the Reset button MacOS

  4. Confirm by clicking “Reset”.

    A confirmation dialog should now be displayed, detailing the components that will be restored to their default state should you continue on with the reset process. To complete the restoration process, click on the “Reset Settings” button.

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. (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
  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.

If resetting the Google Chrome policies didn’t fix the issue, it will be 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

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.

Mozilla Firefox

If you’re having problems with Firefox, resetting it can help. The reset feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks, passwords, web form auto-fill information, browsing history and open tabs.

  1. Go to the “Help” menu.

    Click on Firefox’s main menu button, represented by three horizontal lines. When the drop-down menu appears, select the option labeled “Help“.
    Click on the Firefox Menu button then select Help MacOS

  2. Click “Troubleshooting Information”.

    From the Help menu, click on “Troubleshooting Information“.

    If you’re unable to access the “Help” menu, type about:support in your address bar to bring up the Troubleshooting information page.

  3. Click on “Refresh Firefox”

    Click the “Refresh Firefox” button in the upper-right corner of the “Troubleshooting Information” page.
    Click on the Refresh Firefox button MacOS

  4. Confirm.

    To continue, click on the “Refresh Firefox” button in the new confirmation window that opens.
    Click again on Refresh Firefox button macos

  5. Click on “Finish”.

    Firefox will close itself and will revert to its default settings. When it’s done, a window will list the information that was imported. Click on the “Finish“.

Your old Firefox profile will be placed on your desktop in a folder named “Old Firefox Data“. If the reset didn’t fix your problem you can restore some of the information not saved by copying files to the new profile that was created. If you don’t need this folder any longer, you should delete it as it contains sensitive information.

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.
