    Removing A Computer Virus From A Mac

    If you use a Mac, you may be under the impression that your computer cannot get a virus. Unfortunately, this is a misconception. There are fewer viruses that target Macs compared with the many that target PCs, but Mac viruses do exist.

    Some Mac viruses are designed to trick users into thinking they are anti-virus products. If you accidentally download one of these, your computer may be infected. Three examples of Mac viruses of this type are MacDefender, MacProtector, and MacSecurity.

    If you think your Mac has a virus, here are six steps to follow to remove it:

    • Quit the application or software that seems to be affected.
    • Go to Activity monitor and search for known Mac viruses such as MacDefender, MacProtector, or MacSecurity.
    • If you find one of these viruses, click Quit process before quitting Activity monitor.
    • Next, go to your Applications folder and drag the file into your Trash.
    • Remember to empty the Trash folder afterwards to permanently delete the virus.
    • Now make sure your software and apps are up to date to benefit from the latest security patches.

    To ensure nothing is missed and to keep your Mac protected, consider installing a running an anti-virus solution if you do not already have one. We recommend comprehensive internet security solution like Kaspersky Total Security.

    What Is A Computer Virus

    A computer virus is a type of malware designed to make self-replicate, i.e. to make copies of itself on any drive connected to your computer.

    Computer viruses are so-called because, like real viruses, they can self-replicate. Once your computer is infected with a virus, this is how it spreads. When a computer virus infects your computer, it may slow it down and stops it working properly.

    There are three main ways that your computer may have become infected with a computer virus.

    The first way your computer could become infected from removable media, like a USB stick. If you insert a USB stick or disk into your computer from an unknown source, it may contain a virus.

    Sometimes hackers leave infected USB sticks or disks in peoples workplaces, or public places like cafes to spread computer viruses. People sharing USBs may also transfer files from an infected computer to one that isnt infected.

    Another way your computer become infected with a virus is through a download from the internet.

    If you are downloading software or apps to your computer, ensure you do so from a trusted source. For example, the Google Play Store or Apples App Store. Avoid downloading anything via a pop-up or a website you do not know.

    The third way your computer could become infected with a virus is if you open an attachment, or click on a link, in a spam email.
