Thank you a lot. You saved my day!
My mom had this virus and was unable to remove it. I was helping her and tried everything I could, plus she spoke with three Level 2 Apple techs and in the end, they could not help, but FINALLY, these instructions solved the issue. This was posted by Skanson on another post. I changed around the instructions just a bit to make them more clear. If you have tried the other stuff and cannot remove the virus try this. It has worked for me and others.
"weknow.ac" changes a group of Chrome policies so as to set a new default homepage, new tab behavior, etc. You can see your current Chrome policies by typing chrome://policy/ into your URL bar. If you're infected, it should be very obvious as the half-dozen or so policies changed by weknow will be displayed.
Use the command line to delete / modify the affected policies. You do this by opening up "Terminal" and copy and paste each of the following entries below. I did each one at a time. I copy and pasted the first line and then hit enter and then went to the next until I had finished all 6 below:
defaults write com.google.Chrome HomepageIsNewTabPage -bool false
defaults write com.google.Chrome NewTabPageLocation -string "https://www.google.com/"
defaults write com.google.Chrome HomepageLocation -string "https://www.google.com/"
defaults delete com.google.Chrome DefaultSearchProviderSearchURL
defaults delete com.google.Chrome DefaultSearchProviderNewTabURL
defaults delete com.google.Chrome DefaultSearchProviderName
Quit Chome and restart it and voila the virus will be gone. I tried everything and 3 phone calls with Apple and this was the only thing that worked.
Please use the manual instructions. Do not download anything.
Thank you, thank you.
Spent almost 3 hours working on this tonight and then I found you.
Thank you.

first link is dead..
works perfect
AWESOME ! Thank you SO much ! It worked smoothly.
Chrome is not an Apple browser, Safari is.. This is why unable to resolve. If having issues with third-party browsers, you would want their support, i.e. Google.
brittier826 you responded to me but I typed the directions on how to solve this on Chrome. No need to contact Google. The directions are above. You can see how it worked for many people already and they were appreciative.
No if you follow the post it will correct the situation... Most case malware like this changes the os not the actual program The users is this forum are generally very good at helping with mac OS
Thank you so much! Worked wonders. I thought I was able to get rid of weknow.ac before but was surprised when it popped out and replaced my incognito browser.
Yeah I didn't like that when I was helping my mom and it even took over Incognito. These trojans are getting smarter and smarter.
Thank you so much for typing out the steps and commands. I spent the whole day clearing the we-know and it was still messing up the Chrome. I tried MalwareByte and CC something and I agree with the above that installing more stuff is adding to the confusion, and want money to fix the problem -I wouldn't know what they are doing with my Mac either. So relieved.
Bonjour ChanelCinq, j'ai aussi ce problème de navigateur depuis quelques jours je n'arrive pas en m'en débarrasser... j'ai essayé ta manip mais je n'ai pas réussi.. Si tu as d'autres conseils a me faire part je suis preneur
Merci d'avance
I just spent over an hour on the phone with mac support. We were able to remove weknow.ac from Safari but not from Chrome. I used the suggestions above and it worked like a charm (once I figured out where Terminal is (for those of you who don't know, go to Finder, Applications, Utilities, Terminal). Thank you!!!
After deleting Chrome several times, and using the Malware and every other step in the world I still did not get rid of the problem. I looked at this and typed it in and it finally worked.
