Launch Agents and Daemons: Where else to look

So far we’ve covered browser Extensions, Applications, and Login Items trying to remove malware from your Mac. But these are not the only locations where malicious agents may be hiding. Another type of system services that could be affected by malware are the so-called Launch Agents and Daemons — yes, the name does derive from the word demon. These are small helper programs that stealthily run in the background, like software updaters or automatic backups.

While Launch Agents and Daemons are two different entities, both can be infiltrated by malware. As it often happens, trojan apps would place their executable files within the Launch Agents folder. The result — the virus app launches automatically and potentially harms or steals your data.

How to remove daemons and agents from the Mac’s startup

1. Click Finder.
2. Choose Go > Go to Folder.
3. Type in: /Library/LaunchDaemons

For Launch Agents, repeat the steps above, but this time search in 2 more locations:

/Library/LaunchAgents

~/Library/LaunchAgents

Inside you’ll find a bunch of PLIST files and if some of them look suspicious to you, delete them. Sure, the names of these files may not be very telling, but if you already know the problematic app that you are after, knowing this folder may help you fully extinguish it.

Don’t forget to reboot your Mac — until you do, all these files are still in memory.

One more way to remove daemons, agents, and plug-ins

1. Download CleanMyMac X (it’s free to download).
2. Install the app.

4. Click Perform.
