Problems caused by AristotleLookup

You might first notice AristotleLookup on your Mac when it appears in a pop-up, asking for you to allow it to accept incoming network connections. Whether you allow or deny, the pop-up appears again and again.

AristotleLookup is an app and a browser extension. It changes network settings that cause internet slowdown. It installs a couple of configuration profiles to force your browsers to go to certain websites (like Anysearchmanager) when you try to use internet search. And AristotleLookup gets added to your startup apps.

Trying to delete AristotleLookup or undo its settings doesn’t usually work because these changes get reversed every time you restart your Mac. More unwanted apps might show up, like SystemHelper, GlobalDeskSearch, UniversalWebSearch, StudyDisplay, NameSync, and others. They usually use an icon of a white magnifying glass on a green circle (though the shade of green varies).

Internet connection might be a bit unstable, with it dropping and some online apps (the browser, the email app) crashing from time to time.

Another notable thing is that AristotleLookup the browser extension has access to the sites that you visit, which means that it can read not just what sites you go to, but what you search for and which ads you click on. When just your browsing history can reveal sensitive information, it’s disturbing how bad AristotleLookup having access to all your data on all sites could be.

Information about what you do online is great for advertisers, though. And that’s AristotleLookup’s main goal – to flood you with ads and to make you click on the links it wants you to click on. Manipulating the browsing of all their victims – allows AristotleLookup’s creators to make money.

AristotleLookup's icon is a green circle with a white magnifying glass.

How adware gets installed

You didn’t install AristotleLookup on your Mac for its great features, no question about it. So, how did it appear? There are a few possibilities:

  • AristotleLookup was bundled with a free app. Some free apps include optional offers – applications that get installed automatically with the app, unless you explicitly refuse them. These offers tend to be hidden and tucked in terms of service or advanced installation settings. They’re easy to miss.
  • Malware in the form of fake software updates. Fake updates, such as the ones that look like Flash Player, are used to trick people into downloading and installing malware and adware. AristotleLookup is very likely to spread this way.
  • There’s the chance that a trojan that was already on your Mac downloaded and installed AristotleLookup at some point. It should be removed along with AristotleLookup so that it won’t cause any more problems.

Using a good anti-malware program would be helpful in avoiding infections. It’s also important to be careful and skeptical online. Remember that there are a lot of malicious websites out there that’ll say anything to trick people.

How to remove AristotleLookup

The best and quickest way to remove AristotleLookup is with an anti-malware app, like Combo Cleaner, Malwarebytes, etc. Because removing AristotleLookup normally doesn’t work, you need to find and delete some specific files, and anti-malware programs make it much easier than doing it manually.

However, you can do it manually.

First, it’s recommended to start your Mac in safe mode. Just hold the Shift button while you reboot. This stops third-party apps from running.

Then open Finder, Go -> Go to Folder. Type in the folder names “Library/LaunchDaemons”, “/Library/LaunchAgents”, “~/Library/LaunchAgents”. Find and delete the files with “AristotleLookup” in their names.

Also, go to System Preferences -> Profiles and remove the profiles with “AristotleLookup” in their name. For a lot of people, that’ll be all the profiles on their Mac.

In System Preferences -> Users & Groups -> Login Items, remove any items that you don’t want to run automatically whenever you start your Mac.

Finally, remove the AristotleLookup app from the Applications folder and the AristotleLookup extension from your web browsers (instructions below).

It’s still advisable to scan your Mac for other malware, just to make sure it’s clean.
