Viruses and malware can wreak havoc on your system, often altering critical settings, corrupting system files, or interfering with your internet connection. While removing the virus is a crucial first step, many users find themselves facing a new problem: no internet connection after the removal process. This issue arises because some malware modifies network settings, disables essential services, or corrupts network drivers. Fortunately, you can restore your internet connection with a few troubleshooting steps. In this guide, we’ll walk you through the process of diagnosing and fixing your internet connection after removing a virus.

Why Does the Internet Stop Working After a Virus Removal?

When a virus infects your system, it often modifies your network settings to monitor your activity, redirect traffic, or block specific websites. Even after the virus is removed, these changes can persist, causing connection issues. Here are some common reasons:
  1. Modified DNS Settings: Malware may change your DNS (Domain Name System) settings, redirecting your traffic through malicious servers.
  2. Corrupted Network Drivers: A virus can damage or corrupt your network adapter drivers, preventing your computer from connecting to the internet.
  3. Disabled Network Services: Certain malware disables critical Windows services, such as the DHCP client or DNS client, which are essential for internet access.
  4. Firewall or Security Software Issues: Some malware modifies your firewall settings, blocking internet access even after removal.
  5. Proxy Server Settings: Malware may enable a proxy server, causing your browser to fail to connect to the internet.
  6. System File Corruption: Some viruses damage essential Windows system files required for networking.

Fix internet connection after malware removal

Before changing network settings, check whether another device can connect to the same network. Keep a record of any custom DNS, VPN, or proxy settings. On a work or school device, ask the administrator before resetting them. If this PC is offline, download the scanner installer on a clean device; tools that require cloud updates may still need a working connection.

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.
Malware that hijacks the DNS or Proxy settings can target Windows and Mac devices, so we’ve covered both operating systems below. Depending on which operating system is installed on your computer please click on the operating system icon below and follow the displayed steps to fix your Internet connection and remove malware from your device.

Fix Internet Connection After Removing Malware for Mac

To fix your Internet connection on Mac, follow these steps:

STEP 1: Remove Malicious Proxy server from your Mac

In this first step, we will check go through your Mac settings and remove any malicious server configuration.

  1. Open System Settings

    Click the Apple icon then select the System Settings… option.

  2. Click Network

    Select Network.

  3. Click Details

    Select your active connection in System Settings → Network, click Details, and open Proxies. Record existing values before removing only a proxy you have confirmed is unwanted.

  4. Review Proxies and remove only unwanted entries

    In Proxies, turn off only an entry you have confirmed is unwanted, then click OK. Keep legitimate work, school, VPN, or filtering settings. Test the connection; do not disable every proxy simply because one is configured.

STEP 2: 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, DNS or Proxy Hijackers 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 Settings”

    From the Apple menu, select System Settings.

  2. Open General, then Device Management

    In System Settings, choose General → Device Management. Select an unwanted profile and use the remove control only after checking what it manages. If it belongs to work or school, contact the administrator.

    If Device Management has no profiles, continue to the next step. That rules out a configuration profile as the cause of a locked setting, not other unwanted software.

  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.

STEP 3: Remove DNS or Proxy Hijackers from your Mac Browser

In this third step, we will reset the browser back to its default settings to remove any malicious browser extension, unwanted search engine, or spam browser notifications.

    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. Click on Reset Settings to restore Google Chrome to its default settings MacOS
If the above steps didn’t help you remove malicious browser extensions from Chrome for Mac, 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“. 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

    Only if Chrome still cannot be repaired: back up your bookmarks and needed profile data first. Remove the Chrome application through Finder, then reinstall it from Google. The Google folders listed below may also contain data for other apps; do not delete them as a group. A reinstall does not remove legitimate organization policies or guarantee malware removal.

    If Chrome still cannot be repaired, quit it, open Finder → Applications, and remove Google Chrome.app after backing up needed browser data. Reinstall from Google’s official website. Do not follow old instructions to erase every Google application folder. The paths below are reference locations from older Chrome troubleshooting, not a deletion list. Keep the shared Google folders: they can hold data for other applications. If a clean-profile test is needed, back up the affected Chrome profile and get help identifying that specific profile before moving anything.
    • /Applications/Google 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.
Remove DNS or Proxy Hijackers from Safari
To remove malicious browser extensions, unwanted search engines, or spam browser notifications from Safari we will go through its settings.

  1. Go to Safari’s “Settings”.

    On the menu bar, click the “Safari” menu and select “Settings”.

  2. Check Homepage.

    This will open a new window with your Safari preferences, opened to the “General” tab. Some DNS or Proxy 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. Change Homepage in Safari

  3. Click “Extensions”

    Next, click on the “Extensions” tab. Click on Extensions MacOS

  4. Find and uninstall malicious browser extensions.

    The “Extensions” screen will be displayed with a list of all the extensions installed on Safari. Scroll through the list and search for any unknown or suspicious extension, and then click on “Uninstall” to remove it. 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. Click on Uninstall to remove malicious browser extension

  5. Remove spam push notifications.

    Click Settings, click Websites, then click Notifications. Deselect “Allow websites to ask for permission to send push notifications”. Deselect Allow websites to ask for permission to send push notifications
If the above steps didn’t help you remove the DNS or Proxy Hijackers side-effects from Safari, you can follow the below steps:
  • Workaround for greyed out Safari’s homepage In some cases, after being changed by DNS or Proxy 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 Settings 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“. 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 present, do not delete it as a routine fix. Use Safari → Settings → Extensions and Privacy → Manage Website Data to remove the unwanted extension or affected site data, then reopen Safari
