How to remove AccessibleBoost
Delete malicious files
Reboot your Mac into safe mode. Safe mode will stop AccessibleBoost and other unnecessary apps from running automatically. Hold the Shift button during the boot to access safe mode as it’s explained in this Support.apple.com article.
Run an anti-malware scan (with Combo Cleaner, Malwarebytes, or another app that you are comfortable using). AccessibleBoost will be detected by most scanners as AdLoad, AdWare, or Malicious (Virustotal.com).
AccessibleBoost likely places files in your Library folders to keep itself from being removed. As long as you’re in safe mode, you should review the contents of those folders and delete the files that are related to AccessibleBoost.
Open Finder -> Go -> Go to Folder and type in:
- /Library/Application Support,
- ~/Library/Application Support.
Look in them for files with suspicious names – ConnectionIndexer, com.QueueAlgorithm.plist, and similar names; files and folders named a random set of characters; files that were added recently). As well as files with “AccessibleBoost” in their names, of course.
Suspicious browser extensions also need to be deleted.
Check OS settings
There’s still something to do for getting rid of AccessibleBoost in System Preferences:
- In Profiles, select all items that you did not add yourself, then remove them by pressing the minus ‘-‘ button at the bottom of the window. Profiles are used by AccessibleBoost to force web browsers to open certain sites and redirect searches.
- In Users & Groups -> Login Items, select and remove items that you didn’t add.
- Open Network -> Advanced -> Proxies, then deselect proxies if you didn’t select them. AccessibleBoost and other AdLoad infections sometimes use this setting to hijack internet traffic.
What is AccessibleBoost
AccessibleBoost is adware of the AdLoad family. It hijacks traffic, changes what sites web browsers open, and logs data about the victim.
If your browser suddenly started opening Yahoo, Safe Finder, or another site to deliver your search results, if there are too many ads, random sites open in your new tabs, you can’t open some sites, or experience other internet connection problems, then adware probably infected your Mac.
AccessibleBoost has the ability to collect data about your computer, as well as your browsing data. This data is useful for advertisers who want to target users. It’s a huge privacy problem.
The AccessibleBoost app runs with browsers. There’s also an AccessibleBoost extension for some Safari versions.
AccessibleBoost usually spreads as fake Flash Player updates:
- Warnings that Flash Player needs to be updated appear online, mostly on (not exactly legal) sites for movie and TV show streaming.
- Although the warnings are only ads, people mistake them for real warnings and download the files that these pop-ups are offering.
- Installation instructions tell users to get around Gatekeeper’s warnings (not in these exact words) to install Flash Player, along with AccessibleBoost adware.
Trojans are programs that trick victims into downloading and installing malware themselves. Keep in mind that AccessibleBoost is not related to Flash Player or to Adobe whatsoever. But since Flash’s name is so widely known and trusted, it’s still used by malicious actors to trick people into downloading and installing shady files.
