ConnectionIndexer is a malicious app that collects data about the victim and changes web browser settings. As a result, it injects ads into webpages and changes the default search engine to Yahoo, Bing, or another, lesser-known one. While ConnectionIndexer is only adware, it can be hard to get rid of – sometimes, it returns after being deleted.

What is ConnectionIndexer
Adware and spyware
ConnectionIndexer is adware. If you got it on your Mac, it manipulates the settings of your web browsers to force them to open certain affiliated websites. You see the ads that they show and the ad-publishers make money.
ConnectionIndexer’s biggest danger is the ads that it shows and the sites that it promotes. These ads are likely to be low-quality and even malicious. Aggressive and loud pop-ups and redirects that lead to scam sites – that sort of thing can lead to more infections, to personal information being exposed, and even to more harmful scams.
In addition, ConnectionIndexer could work as spyware. It has the ability to read your data on the sites that you visit, which includes search queries, ads clicked, and potentially even passwords.
The network settings may have been changed by ConnectionIndexer, too. This would make your computer send traffic to the server that ConnectionIndexer set, which slows down the internet a little.
Worst of all, ConnectionIndexer might download other adware and malware in secret. It appears to be AdLoad, after all, and AdLoad trojans, besides advertising and spying, are known for downloading additional adware that you might also need to remove.
Negative side effects
You might experience a few side effects thanks to ConnectionIndexer:
- Slow internet and some websites not opening.
- Online apps breaking, crashing, refusing to work.
- Being unable to sign in to your online accounts.
- Slow Mac, beachballing.
- Redirects and excessive ads in the browser, download links not working properly.
- Pop-ups covering the screen and hijacking the mouse cursor.
ConnectionIndexer is similar to SectionIndexer, DivisionFormat, OperativeDesktop, FormatConnection, QueueAlgorithm, InitiatorSignal, and others – you can probably see the pattern in their names: vaguely IT-related nouns concatenated into a word. These adware infections are really common for Macs.
They, including ConnectionIndexer, spread in fake FlashPlayer updates, other fake updates, and in infected freeware installers. If you’ve recently downloaded and installed something from an unofficial site (though you might have not suspected it at the time), that might have been how ConnectionIndexer got on your Mac.
How to remove ConnectionIndexer
Luckily, it’s possible to get rid of this adware.
You can delete the ConnectionIndexer app (drag it to Trash) and browser extension (instructions below), as well as the configuration files it created (System Preferences -> Profiles) and its login items (System Preferences -> Users & Groups -> Login Items).
It’s also important to look at your proxy settings (System Preferences -> Network -> Advanced -> Proxies) and to deselect any proxies that might have been selected by ConnectionIndexer.
However, these settings won’t stick until you remove the files used by ConnectionIndexer.
Delete malicious files
To begin with, reboot your Mac into safe mode. You can do it by holding the Shift button during the boot time (Support.apple.com).
To find malicious files that are related to ConnectionIndexer and other malware, you can use an anti-malware scanner, such as Combo Cleaner, Malwarebytes, or other apps. They can recognize ConnectionIndexer, sometimes.
If you want to review your files manually, open Finder -> Go -> Go to Folder and type in these folder names: /Library/LaunchDaemons, /Library/Application Support, ~/Library/LaunchAgents, ~/Library/Application Support. Check the dates of the files (the newer, the more suspicious, provided that the ConnectionIndexer infection is recent). Delete them or ask the help of an IT professional.
To get out of safe mode, just reboot normally.
