WebFunctionSearch is a malicious app that changes your browser’s search behavior, manipulates your internet traffic, may download more malware, and logs your browsing activities. It spreads with fake Flash Player updates and installs together with other junkware. It’s quite a persistent app that can be difficult to remove.

How to remove WebFunctionSearch
As WebFunctionSearch may not be the only malicious app on your computer, you can use an anti-malware app (Combo Cleaner or whatever app you’re comfortable using) to check your device.
To find and delete WebFunctionSearch specifically, it would be helpful to begin by going into safe mode (Apple.com). WebFunctionSearch can be very persistent, but safe mode doesn’t allow it to run and can make removal easier.
There might be these files on your Mac:
- ~/Library/Application Support/com.WebFunctionSearch/WebFunctionSearch
- /Library/Application Support/com.WebFunctionSearchDaemon/WebFunctionSearch
You can find them by using Finder. In Finder’s menu, press Go, then Go to Folder. Type in the folder’s name (like Library/LaunchDaemons) and Go.
Alternatively, in the Go menu, choose Computer. Then type WebFunctionSearch in the search field and search.
Check all of your browsers for the WebFunctionSearch extension. Remove it if you find it.
Delete the files that have “WebFunctionSearch” in their names. Delete other suspicious files, although not without making a backup of those files first. It’s better to use an anti-malware scanner here, however, not all scanners detect all malicious files.
Fix system settings
Open System Preferences from your Apple menu or the Dock:
- Open Users & Groups, then Login Items. Delete all unwanted and unknown items.
- There might be an item called Profiles. Click it and select the items that are unknown to you. Then delete them. Configuration profiles are meant to force your Mac and your apps to take on certain settings, including search preferences. They are sometimes abused by malware.
- Click Network, Advanced, Proxies. You can see a list of configurations. If one is selected, such as SOCKS, and if you didn’t select it, then deselect and click OK.
Change your passwords
In theory, WebFunctionSearch could have read your passwords, usernames, and other information. In theory, its browser extension was able to see what you were doing online. If you did find WebFunctionSearch’s extension installed on a browser that you use regularly, then you should change your passwords. That is, once WebFunctionSearch is deleted and you’ve made sure that there’s no other malware on your Mac.
What is WebFunctionSearch
WebFunctionSearch is an aggressive adware infection:
- Its extension can read and change the webpages that you have open without worrying about encryption.
- WebFunctionSearch may change your network settings to send your traffic to a server controlled by cybercriminals, exposing your traffic and allowing these criminals to manipulate which websites you see.
- WebFunctionSearch can show pop-up ads.
- It can also download and install more malware.
Overall, WebFunctionSearch might also be called spyware and a trojan. It does things like display pop-ups to hide macOS warnings, using those pop-ups to trick people into unwittingly giving WebFunctionSearch access and privileges.
How it gets installed
Like many macOS threats, WebFunctionSearch uses fake Adobe Flash Player update warnings to sneak onto people’s computers. WebFunctionSearch would have been bundled with a genuine installation of Flash Player, or with no Flash Player at all.
WebFunctionSearch may have been bundled with a cleaner app, such as the infamous Mac Cleanup Pro. This junkware should be removed along with WebFunctionSearch.
Do not trust Flash Player pop-ups if you see them online. Few websites use Flash Player anymore, especially as this technology is being retired.
