SymDaemon is a file connected to the Symantec Antivirus but from time to time viruses may hijack the file and use it to compromise your Mac. The SymDaemon file itself is not a malware but if your Mac warns you against it, it is best to check your computer for viruses.


The SymDaemon App will display pop up messages and windows

If this app is installed on your Mac, you should know about its characteristics and about the potential problems you may face. This app is not a malicious virus so it won’t harm your computer, however, it is still a piece of software that most experts regard as unwanted. Therefore, it is better to get it off your Safari, Chrome, or Firefox browser and remove all changes that it has introduced. Otherwise, if this app is allowed to stay in the browser, it may potentially lead to a number of unpleasant issues, some of which may even compromise your system’s security.

SymDaemon for Mac

SymDaemon for Mac is a Symantec Antivirus file that might get exploited by harmful software programs that seek to infect your Mac. SymDaemon for Mac makes changes in the browser and allow it to display ads that may be hazardous to your Mac.

For instance, if this app alters the search engine and installs a new one, that new search engine may not be as safe as your previous one and may show you questionable results that may lead you to unsafe sites. The new homepage introduced by the browser could also be a potential security hazard as the site it represents may not be reliable and may have dubious contents. All of this means that the longer an app like this one is allowed to stay in the browser, the greater the chance of getting the computer attacked by advanced malware threats such as Trojans or Ransomware.

What is SymDaemon?

SymDaemon is a type of Mac-infecting malware that attacks the browser by getting installed in it and taking control over its settings. The goal of SymDaemon is to make a profit for its developers through the display of paid ads on the user’s screen.

The developers of this undesirable app need you to click on their ads and visit the sites that SymDaemon is tasked with promoting because this is what earns them revenue. Here, popular models such as Pay-Per-View or Pay-Per-Click are employed in order to ensure that the browser-hijacking app earns maximum profit.

The SymDaemon app

The SymDaemon app is unwanted and potentially hazardous software that forces the main browsers on Mac computers to end the user to certain promoted sites. The SymDaemon app can send you to all kinds of sites, some of which may be hosted by cybercriminals.

The best way you can protect your Mac in such a situation is by uninstalling the browser-hijacking app. That way, you won’t need to worry about accidentally clicking on some dubious advert and landing on a site filled with Ransomware, Trojans, or other viruses. To remove the hijacker, we suggest you turn to the removal guide posted below.

Type Browser Hijacker
Danger Level Medium (nowhere near threats like Ransomware, but still a security risk)

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading ComboCleaner to see if it can detect parasite files for you.

The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively, you can simultaneously press (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.



To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading ComboCleaner
a professional malware removal tool.
