How Mac can get viruses from websites

There are a number of ways a Mac can pick up viruses when browsing websites online, the most common of which are through exploit kits and website vulnerabilities.

1. Exploit kits

Exploit kits have become one of the most widespread online threats due to the fact that they’re almost entirely automated and can be executed silently without a user knowing. Hackers use compromised websites to divert traffic to their malicious code, which then infects a user’s system. Once inside, the kit can install malware, ransomware, and other nasty threats.

 

A recent example of this is the HanJuan exploit kit that surfaced in 2015, which uses fake ads and shortened URLs to redirect unsuspecting users to malicious sites. It takes advantage of vulnerabilities in software like Internet Explorer to evade antivirus protections, and it can be used to inject viruses, password stealers, and other dangerous software onto a machine.

2. Website vulnerabilities

Website vulnerabilities are flaws, bugs, or other weaknesses in a website’s HTML code that hackers can use to gain unauthorized access. Once inside, attackers may be able to steal sensitive user information, or they may be able to hack the site to distribute malicious code. Many believe that only malicious websites are dangerous, but that’s not always the case.

 

For example, a vulnerability in the gaming platform Steam, discovered in 2017, allowed for an attack called cross-site scripting (XSS). Attackers could use this to inject malicious scripts into the application, allowing them to steal login information, use funds on other user’s Steam accounts, and even spread malicious software using an auto-download file.

Why some websites have viruses

There are many reasons why websites have viruses, such as bugs or flaws in their code, and out-of-date technologies that allow attackers to exploit them. Some websites, such as those offering pirated content, are more likely to host viruses because of the nature of the service they offer. Be careful.

 

Other reasons include:

  • Failing to install updates or improve website code
  • Fake or malicious ads and pop-ups
  • Hijacked links that redirect a visitor to malicious sites
  • Allowing users to distribute their own files that could be dangerous

How to protect your Mac from viruses on websites

Now you know that you can get a virus by visiting a website on Mac, let’s look at how you can protect your Mac to prevent or remove them. Here are the most effective methods:

  1. Keep your system and software up-to-date
  2. Avoid questionable websites
  3. Use web browser default configurations
  4. Enable the pop-up blocking in your web browser
  5. Use antivirus software

1. Keep your system and software up-to-date

To set your Mac to download software updates automatically, follow these steps:

  1. Open System Settings on your Mac.
  2. Click General in the sidebar, then select Software Update.
  3. Next to Automatic Updates, click the i icon.
  4. Enable Check for updates and Download new updates when available.
  5. To install new updates automatically, enable Install macOS updates.
  6. Click Done.
System Settings on Mac shows the General menu. Click Software Update to enable automatic updates.
Step 1. In System Settings, click General then Software Update
System Settings on Mac shows the Software Update menu. Click the i icon to change automatic update settings.
Step 2. Click the i icon
System Settings on Mac shows the Software Update menu. To turn on automatic updates, enable Download new updates when available.
Step 3. Enable Download new updates when available

Updating macOS and the software you use is the best way to ensure they contain no bugs or flaws that could be exploited by hackers. You can set your Mac to download software updates automatically, while apps can be updated through the Mac App Store or within the app itself.

2. Avoid questionable websites

To avoid a Safari virus from unsafe websites, you can practice these safe browsing tips:

  • Check URLs carefully to ensure you’re visiting legitimate sites.
  • If a browser tells you a website is unsafe, leave it.
  • Don’t click on links sent to you by email or text.
  • Don’t click on suspicious ads or pop-ups.
  • If a website you know doesn’t look right, don’t trust it.

3. Use web browser default configurations

Every web browser has default configurations that are designed to keep you as safe as possible online. Some people like to change the default settings without realizing that some alterations can have a negative impact on browser security.

 

To reset Safari back to its default configuration, follow these steps:

  1. Open Safari, then click Safari > Settings in the menu bar.
  2. Click the Extensions tab.
  3. Select any Extensions you don’t recognize or need, then click Uninstall.
  4. Click the Privacy tab, then select Manage Website Data.
  5. Select the Remove All button, then confirm.
  6. Click the Advanced tab, then enable Show features for web developers.
  7. Select Develop > Empty Caches in the menu bar.
The menu bar on Mac shows the Safari menu. Click Settings to access the settings menu.
Step 1. In the menu bar, select Safari > Settings
Safari on Mac shows the settings menu. Click Extensions, then select an extension and click Uninstall to remove it.
Step 2. In Extensions, Uninstall any extensions you don’t need
Safari on Mac shows the Privacy settings menu. Click Manage Website Data to delete all website data
Step 3. In Privacy, click Manage Website Data
Safari on Mac shows the Manage Website Data menu. Click Remove All to delete all website data.
Step 4. Click Remove All to delete all website data
Safari on Mac shows the Advanced settings menu. Enable Show features for web developers to access the Develop menu.
Step 5. In Advanced, enable Show features for web developers
Safari on Mac shows the Develop menu in the menu bar. Click Empty Caches to remove all cache data.
Step 6. In the menu bar, click Develop > Empty Caches

Note from our team: It’s not possible to restore Safari’s default settings with a single button, unfortunately, but the steps above will remove all website data and third-party extensions, leaving you with a fresh Safari as much as possible. Similar steps can be performed inside third-party browsers like Google Chrome, but it may be easier to uninstall and then reinstall them instead for a default setup.

4. Enable the pop-up blocking in your web browser

Most modern browsers have the ability to block pop-ups that can be used to spread malicious software—one of the most common ways you can get a virus on your Mac from viewing a website.

 

Here’s how to do that in Safari:

  1. Open Safari, then click Safari > Settings in the menu bar.
  2. Select the Websites tab, then click Pop-up Windows.
  3. Next to When visiting other websites, select Block and Notify.
The menu bar on Mac shows the Safari menu. Click Settings to access the settings menu.
Step 1. In the menu bar, click Safari > Settings
Safari on Mac shows the Websites settings menu. Click Pop-up Windows, then select Block and Notify to block all website pop-ups.
Step 2. Click Pop-up Windows, then select Block and Notify

You can also block settings in other web browsers like Google Chrome, Microsoft Edge, and Firefox, and in many cases, this feature will be enabled by default. If not, the instructions are similar to those listed above.

5. Use antivirus software
