What is SysJoker?
SysJoker is considered to be a backdoor malware. It can gain access to the system level of your Mac with or without your permission and bypass all regular security measures, usually by exploiting a security flaw of sorts.
How can a Mac get infected with SysJoker, and how can it harm your Mac?
The most common way for SysJoker to infect a Mac is through user installation. It starts as a seemingly harmless font file. Then, once you install that, it connects back to a server to download more invasive software.
After SysJoker reports back to its server, it also sends detailed and private information about your computer. This way, it can track your MAC address, serial number, IP address, and more.
How to remove SysJoker malware from Mac
The encouraging news is that even if you’ve found out your Mac has been infected by SysJoker, you’re not out of luck. There are a couple of surefire ways to get rid of it and clear up your Mac.
Get rid of SysJoker manually
In case you’re somebody who likes to do things yourself, here is a manual way to get rid of SysJoker. It is a bit long and time-consuming multiple-step process, but with these instructions, it should feel like a piece of cake. First and foremost, quit anything related to SysJoker. Simply follow these steps:
- Open Activity Monitor.
- Scroll through the list and find anything related to SysJoker.
- Click the X inside the octagon.
- Then, click Force Quit to confirm.
The next part of the process is to delete one of your software update preferences. Here’s how:
- Open a new Finder window.
- Click Go > Go to Folder.
- Copy and paste this path: /Library/LaunchAgents.
- Right-click or Control-click on the file com.apple.update.plist and click Move to Trash.
You don’t need to worry about this file. It’s a standard operating system cache file (meaning that after your Mac restarts, it will recreate a new fresh copy not infected by SysJoker).
At this point, let’s go ahead and restart your Mac.
