HOW TO FIND OUT IF YOU HAVE BEEN HACKED:
How to Remove Malware From Your Mac Step 1:
Disconnect from the Internet Before you do anything else on your Mac, you must disconnect the Internet to keep it from transmitting any of your information back to the malware server or infecting other devices. Do your best to stay offline.
If you need to go online to download a tool, immediately disconnect once it finishes and doesn’t reconnect once you have what you need. It may help to print these instructions before disconnecting.
Step 2:
Enter safe mode Isolate any issues with your Mac by entering safe mode. Do this by starting or restarting your device, then immediately hold the shift key. The Apple logo should appear on your screen. If this doesn’t work, learn more here.
Step 3:
Refrain from logging into accounts Many forms of malware aim to access your sensitive information. They do this by poaching your login credentials after tracking your keystrokes or lifting your password from your screen or clipboard. Prevent losing any login info by avoiding logging in at all.
Step 4: Delete temporary filesDelete temporary files that may have been installed by malware by quitting any apps you have open — right-click them, select “Quit” and then:
Step 1: From Finder select “Go” in the top bar
Step 2: Click “Go To Folder” and then type or copy and paste “~/Library/”
Step 3: Go to the “Cache” folder
Step 3: Move all files from the cache by clicking “Move to Trash”
Step 4: “Empty” the Trash
Step 5: Check your activity monitor If you think you have malicious software on your Mac, then you must find it in the Activity Monitor and stop it. Through the Activity Monitor, you can see all of the applications running on your computer and how each one affects its performance. Locate the malicious software and delete it through the Finder.
Step 1: Go to Finder and select “Applications”
Step 2: Click “Utilities”
Step 3: Go to the “Activity Monitor”
Step 4: Double click an application and then click “Quit”
Step 6 – Run a malware scannerNow you’re ready to actually cure your Mac of its malware infection. Luckily, running a malware scanner is usually enough to get rid of most standard infections. If you already had an antivirus program on your device, you should download an on-demand malware scanner that’s different than what you’re using for antivirus.
Download a scanner from a reliable source, such as Panda’s Cloud Cleaner, run it, and then install security software that works constantly in the background to protect you from existing and emerging security threats. Programs such as Panda’s Antivirus for Mac work great for this.
Step 7: Fix your web browser In most cases, malware will modify the homepage of your Internet browser so that it can reinfect your device, show you lots of ads, slow down your browsing and flat out annoy you. Verify that the homepage address is legitimate and then move on to check your browser for malicious extensions.
