What is AssistiveFile

AssistiveFile is malware that affects macOS computers. It affects web browsers, and among those, Safari is the one that is most affected.

Here are some of the annoying effects that AssistiveFile may have on your computer:

  • Open unexpected sites in your browser. Periodically open new tabs in your browser.
  • Inject ads into your webpages – ads that are obnoxious and potentially dangerous.
  • Read your data while you’re browsing. Potentially, AssistiveFile could even steal passwords, payment info, and other data.
  • Start and quit your browsers on their own.
  • Show strange and pointless pop-ups, like one saying that installation was completed or that you don’t need to update Safari.
  • More suspicious extensions and other apps being installed.

With AssistiveFile being installed, you might notice sites like SearchMarquis or Safe Finder being opened when you try to search the internet. These sites are not very dangerous on their own, they just show too many ads.

Overall, AssistiveFile’s effects include more ads in the browser and more malware being downloaded.

The icon of AssistiveFile is a blue/green circle with a white magnifying glass.

How AssistiveFile gets installed

Most likely, AssistiveFile was installed because of a fake update warning, like one of these Adobe Flash Player pop-ups. These types of warnings are nothing more than elaborate advertisements. They’re obviously scams, so only certain kinds of websites show them: sites that don’t have strict rules for their ads.

Infected sites can also show malicious ads on your screen. Sites that get infected are usually old and niche. If a malicious redirect was on a site, you can write an email to the site’s administrators. They might not know about the problem.

Once AssistiveFile is downloaded (often in a file called “Player” or “Installer”), if you install it, it might still look like a Flash Player update and nothing suspicious. Only after the installation does AssistiveFile show up.

AssistiveFile may not be installed alone, either. A shady Mac cleaner/optimizer might start spamming pop-ups on your screen, additional browser extensions may get installed.

Trying to remove AssistiveFile might not work because there are settings, start-up files, and configuration profiles anchoring it on your system. But AssistiveFile might get replaced by another app, like AdjustableProduct, ConnectionFormat, ExpandedSkillInitialWindow, and others.

How to remove AssistiveFile

AssistiveFile’s app can be deleted but that might not be enough to remove it for good.

Scan your computer with an anti-malware scanner, such as Combo Cleaner, Malwarebytes, or another. If needed, reboot your Mac in safe mode. Safe mode stops AssistiveFile from running itself.

Delete the AssistiveFile app and browser extensions.

Let your anti-malware scanner find and delete malicious items belonging to AssistiveFile, but that’s not all. Open System Preferences in the Dock or the Apple menu:

  • Find an ion called Profiles. Click it, then in the new window, select and remove all the items that weren’t added by you or your administrator. In general, scrubbing your Profiles tends to be the most helpful when getting rid of malware on Macs.
  • Open Users & Groups, then go to Login Items. Select and remove all the items that weren’t added by you.
  • Open Network, Advanced, Proxies. If there are protocols configured that you didn’t configure, deselect them and save. This is especially important, so check it again after you’ve removed AssistiveFile.

Once you’re done, just reboot to get out of safe mode.

In case the above isn’t enough to remove AssistiveFile, there is something else you can try. Repeat the same, but also look for malicious files manually. Open Finder. In its Go menu, find Computer. In the newly opened window, type in AssistiveFile. Delete all of the files that are found.
