Removing Viruses, Spyware And Adware From Your Mac
Are you worried your MacBook has a virus, spyware or adware installed on it? A common myth in the computer industry is that Apple products "can't get a virus".
This is a great PR move for Apple but hurts the consumer as it simply isn't true. The truth is that as Apple has gained market share in the consumer computing industry, creators of malicious programs have taken notice and begun to direct their efforts at the OSX, macOS and iOS systems. While it is true that there are more types of viruses, adware and general spam directed at the Windows operating system, it is naive to think that you are 100% safe just by virtue of owning an Apple computer.
If you've begun to notice odd behavior, slow load times and irritating popups or redirections when browsing the web then you may be the victim of a malicious program. Your MacBook can become infected by browsing unsafe websites, downloading unsafe files or clicking unsafe links. We'll discuss how to best keep yourself safe and remove any existing types of virus or malware on your machine.
Identifying MacBook Viruses and Malware
Malware (a catch-all term for malicious programs running on a computer) can drastically reduce the power and efficiency of your machine. Often time, these programs will run processes in the background that perform a multitude of tasks. It can be anything from copying keystrokes or sensitive data to turning your computer into a "zombie" node. The end result is that it steals processing power away from the core functions of your computer and can leave you with a machine that has drastically reduced performance.
If you've noticed that your computer is running slower than it normally does, this can be a sign that you've accidentally installed a malicious program. Another symptom of infection is odd behavior. Specifically, popups, when you do not expect them or redirection while using your internet browser, can indicate that you have malware installed as well. Redirection can occur when malware takes over your default search engine and forces your search queries to redirect to advertisements installed by the malware creator.
You should be aware that viruses and malware on your MacBook can hide in various places. This means they can be background processes, in your browser, from a file you may have downloaded, and more. It is important to search everywhere possible for lurking threats as these programs can be exceptionally well-hid from the average user. It will not be as obvious as opening up Activity Monitor and removing a running process.
For the best way to check if your MacBook has a virus, spyware or adware installed, we recommend using CleanMyMacX. This piece of software will scan your computer and check for any malicious programs that may have been installed and are hiding in background processes.
