Final Steps: Rooting out the virus completely
The next steps are the most important because so far we have cleaned your Mac on the surface level. Now it's time to go deeper and delete WeKnow virus from the system directories.
STEP 1.
Open Chrome, then paste this string into the URL field and press Return:
chrome://policy/
You will see a window like this one:
Now see what's written in the Level column
If it reads 'Recommended', unfortunately, you will have to reinstall Chrome completely. This is because WeKnow has hard-coded itself into administrative settings of Chrome. If it reads 'Mandatory', go to STEP 2.
For additional check:
Go to Applications/Terminal Open Terminal, paste the following command and press Return:
defaults read com.google.Chrome
Now, look through the results. If you see anything related to WeKnow there, again, the only remaining solution is to simply uninstall Chrome. You can use CleanMyMac X for this purpose. It's has an Uninstaller tool that will wipe out the remaining traces of any app it deletes.
STEP 2.
With this step we will remove WeKnow virus from the Mac's library preferences associated with your username.
Open Finder, go up to the Go menu in the menubar -> Go to Folder, and paste this directory:
/Library/Managed Preferences/[your username]
You should enter [your username] as shown in System Preferences/Users & Groups. In my case, it's 'Admin' but may be different on your computer.
Open the folder. Now look for a “com.google.Chrome” file there.
