Remove Power Colors Browser Extension (Virus Removal)

Remove Power Colors browser hijacker from Safari

To remove the Power Colors browser hijacker from Safari we will check if there are any malicious extensions installeded 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”.
   

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.

   

3. Click “Extensions”

   Next, click on the “Extensions” tab.
   

4. Find and uninstall Power Colors.

   The “Extensions” screen will be displayed with a list of all the extensions installed on Safari. Scroll through the list until you find the Power Colors extension, and then click on “Uninstall” to remove it.

   There may be other malicious extensions installed. 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.

   

5. Remove spam notifications ads

   Click Preferences, click Websites, then click Notifications. Deselect “Allow websites to ask for permission to send push notifications”.

   

If the above steps didn’t help you remove the Power Colors 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 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“.
     
  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

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

If the above steps didn’t help you remove the Power Colors 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, a malicious program may have 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“.
     
  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 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.
