How to remove InitiatorSignal
Delete malicious files
InitiatorSignal is malware and it hides its files to keep itself installed. If you tried to delete it and failed, then those files must be hiding on your computer still. They might be found in these hidden folders:
- ~Library/Application Support/
- /Library/Application Support/
If InitiatorSignal refuses to be removed, you should check all of the places listed above and remove suspicious items if there are any.
The best way to do this is to use an anti-malware program, like Combo Cleaner, Malwarebytes, and others. Start your Mac in safe mode. Do it by holding the Shift button on your keyboard while booting your Mac. Delete the items that scanners flag as suspicious or malicious.
To open hidden folders, open Finder, Go, Go to Folder. Then type in the Folder name. To delete some of the files, you might have to provide your password.
Restore other settings
Configuration profiles can be found in System Preferences, Profiles. Delete all the ones that you didn’t create.
Profiles may be used by InitiatorSignal to force certain settings of web browsers and network settings. Once the profiles are gone, your settings are back in your control.
Browser settings can be restores as described in the last section of this post. The default search engine, start page, and other settings need to be checked. Malicious browser extensions need to be removed.
Proxy settings can be found in System Preferences, Network, Advanced, Proxies. InitiatorSignal might have set a proxy. If it did, you can deselect it and save the settings.
What InitiatorSignal does
InitiatorSignal may try to change your network settings which can severely slow down some apps. This can make browsing very frustrating.
InitiatorSignal also installs browser hijackers and changes browser settings. The result is obvious:
- search redirects (to Yahoo, Bing, or other sites),
- ads injected into webpages,
- a hijacked start page (SearchMaquis, SearchBaron, Safe Finder, etc.),
- the InitiatorSignal browser add-on can read user data, like search history and browsing history,
- it can redirect to malicious sites like the IOS /MAC Defender Alert scam site or malware download sites.
InitiatorSignal’s configuration profiles allow it to reinstall malicious extensions and enforce search engine and new tab settings regularly.
How to avoid adware infections
InitiatorSignal might get downloaded by its victims unwittingly. It comes hidden in free apps or fake software updates. These can be found in online pop-ups and shady download sites and they can easily be mistaken for real updates – in fact, they may contain real update installers bundled together with malware. That allows InitiatorSignal and some other adware to sneak in unnoticed.
Files that download and install InitiatorSignal may be detected by antivirus scanners as Trojan.Downloader or another type of Trojan. In this case, InitiatorSignal is a “Trojan” because it tricks people into downloading it.
Using an anti-malware app or an ad-blocker can help avoid malicious sites but it’s not always effective. What’s really important is to make sure that the software being downloaded that it comes from an official source.
But the file containing InitiatorSignal being downloaded is not enough; the Mac user needs to run the installer and agree to all the installation steps. The installer displays fake pop-up windows and gives bizarre installation instructions to trick people into enabling InitiatorSignal despite macOS’ built-in security tools.
Remember, if you find something suspicious, you can always quit an installer mid-way. Don’t ever feel obligated to follow through. And the more pushy an installer is, the more suspicious it is.
