How to Remove Malware from Safari on Mac

Personally, I have been using Safari at work for a long time. In my previous work at a big online processing company, MacOS is used as it is one, if not the most, difficult operating system to attack. Of course, we were dealing with finances after all. Because of this, all our works are done on Safari and I have no issues with it. It is fluid, easy to the eyes, consumes less resources, and secure — as far as I know.

However, as more attackers are shifting their focus towards macOS, mostly due to the fact that most professionals rely on the operating system for their jobs and businesses, safety is no longer guaranteed.

In this article, we will help you diagnose if your Safari is infected with malicious codes and give you instructions on how to fix the issues.

Symptoms of Infected Safari Browser

Now, to help you diagnose if your Safari is infected with malicious codes, we will discuss first what a Safari virus is.

Safari virus is a browser hijacker used to generate web traffic and collect sales leads for some suspicious websites. These websites cover up as something you are familiar with, like PayPal, and will phish on your details to access all your finances and account information.

The following are symptoms if your Safari is affected by this browser hijacker:

  • The ads seem to show up more often than it should be. Mostly in unexpected places like in software, for example, Pages, which doesn’t have ads before.
  • The pop-ups and banners ask you to install software updates, and directs you to a certain website.
  • Your homepage, the moment you launch Safari, redirects you to an unknown website.
  • Usually, a fake tech support website which tells you your Mac is infected.
  • When you click a link in search results, it redirects you to dubious or possibly malicious websites.
  • Unwanted extensions start to appear in your browser, without you installing it.
  • Your Mac suddenly decreased in performance. This shouldn’t be the case as macOS is highly-optimized to run even on older Mac computers.

Other techniques these attackers do is ask you to install an Adobe Flash Player (which is long dead anyway), and other software that seems familiar to you. Don’t panic if the website says you have issues with your computer, and that there is a time on the display urging you to go to a certain website or call a number.

If you notice some of these symptoms, it is more likely that your Mac is infected with such virus. In the next part, we will show you how to get rid of Safari virus on your computer. This Safari malware removal is very easy and you can do it without paying anyone.
