How to Remove Malware from Safari on Mac

Unlike Windows and Android devices, Apple computers are not very popular for being targeted by viruses and malware. Mac and iOS devices possess a rugged security model, which is exceptionally tough to penetrate.

However, over the past few years, cybercriminals have taken advantage of Apple’s ecosystem’s components to inject undetectable malware into computers. Safari being a salient component of iOS and Mac, has been considerably targeted to satisfy the ultimate purpose of the script kiddies and hackers.

These malware injections are dynamic and vary on a large scale and as per the attacker’s purpose. The worst part here is most users are unaware of their web activity and functions.

A few weeks ago, the malware was injected into my Safari browser, causing it to slow down and loading unskippable ads everywhere. When malware hits your Safari browser, it will start unusual behavior and suspicious activities like this.

So if you encounter any suspicious or abnormal activity throughout your browsing session, chances are there might be some malware in your browser.

Thankfully I was able to get the malware out of the Safari browser, but in case you are stuck in a similar position, here are some of the most efficient ways to check and remove malware from your Safari Mac.

Check Malware in Safari Mac

Whenever malware enters your system, it will create certain disturbances and abnormal behavior in your Safari browser. It may redirect you to different pages suddenly and display unwanted pop-up ads out of the blue.

One such example of a potential threat to Safari is the Bing redirect virus, which dominated for a long time in 2019. It is used to redirect the user’s internet traffic to the front page of being without any permission.

And even if users successfully identified the potential threat, no one could understand its purpose or how to check for it.

When browsers like Apple Safari, Google Chrome, Mozilla Firefox, etc., these infections primarily occur in extensions and plugins. So, the first method to confirm such a threat is by identifying suspicious extensions on their browser.

Removing Suspicious Extensions

The primary source of malware in the Safari browser is due to third-party extensions or plugins. These extensions get automatically installed when you visit a questionable downloading website. And as a result, they either show advertisements or use your browser performance power to mine cryptocurrency.

Either way, it’s hard to find them, but the best way to deal with such suspicious extensions is to delete them.

Here are the steps to remove suspicious extensions from Safari browser Mac:

1. Open Safari browser on your Mac.
2. Click on the Safari menu and select the Preferences… sub-menu.
   It will open the Safari Preferences window.
3. Switch to the Extensions tab.
4. Lookup for suspicious extensions installed.
   
5. Select the extension, and hit Uninstall to remove it from Safari.

It will immediately remove the extension and make the browser less vulnerable. However, the extension might already make changes in settings; it is better to check and reset the options to a normal state.

Under the same Safari preferences window —

• Switch to the General tab, and set a preferred homepage for your Safari browser.
  
• Again, switch to the Search tab, and set your default search engine.
  

Restart the Safari browser and check if the problem doesn’t appear anymore. However, if the problem persists in your browser, try the following method on our list.

Reset the Safari settings to the default

Extensions come with special privileges and permissions so that they can alter the setting of your Safari browser. This, in turn, shows suspicious behavior such as unnecessary ads, slow web pages, etc. Resetting Safari settings on your Mac will delete any malicious configuration injected by the malware.

Here are the steps to reset Safari settings to the Default configuration:

1. Launch the Finder window on Mac.
2. Press and hold the Option key and select the Go menu.
3. Select the Library option from the drop-down menu.
   
4. Navigate to Library > Preferences folder.
5. Delete com.apple.Safari.plist file from the preferences folder.
   

We have deleted the default configuration file. Just restart the Safari browser to regenerate the new configuration file that we have deleted. It should clear any malware injections.

Clear Cache and History

The cache is a temporary storage solution for the browser, which helps Safari load certain web pages faster. But if the malware is hiding in the cache files, it will create a problem even after you reset or delete your browsing history.

Furthermore, a filled cache memory may slow down your Safari website performance, so clearing the browser cache every six months is a good practice.

Delete Website Data

Website data comprise special features such as cookies and browsing or behavior patterns. These might also include your log-in sessions or other website identifiers.

If your browser is infected with malware, it can grab sensitive information via website data, so it is good to delete it.

These methods are the most efficient ways to remove malware from Safari Mac and bring your browser back to its normal functioning state.
