- Random crashes;
- Annoying pop-ups;
- Slow internet connection.
Consult this guide and try to figure out if a malware infection is the culprit.
How do I delete malware from my Mac?
If you have antivirus, get in the habit of scrubbing your Mac regularly. For those without antivirus, there are other ways you can take care of a malware infection. Malware on a Mac is quite straightforward to purge – it’s looking at the programs that are currently running and figuring out which ones don’t belong. For these next steps to work, you’re going to need to have administrator privileges.
So how to remove malware from your mac? First, we need to cleanse your downloads. You may have accidentally taken on an unwanted digital stowaway. A lot of malware likes to piggyback off a seemingly innocuous download.
- Open up Finder. Click on the Downloads option along the left of the window.
- Open all your recent installation files and look for any suspicious files that look like they don’t relate to whichever program you originally downloaded. Send them all to the Trash.
- Click on Applications above Downloads. Scroll down and open the Utilities folder.
- Click on Activity Monitor – it will be the first app in the folder.
- What you’ll see next is a list of everything your Mac is currently engaged with. Look for anything that you have no knowledge of activating. Double click on the app or program and click on Quit. Take note of the name of the item whose processes you just stopped.
- Go back to your Applications and find those troublesome malware files. Use Command + f to find those file names instantly. Move them all to the Trash.
- Empty the Trash!
