Yes, I followed those instructions exactly.
I had the client try to change the home page, switch to another tab before pressing return and then confirm the home page change. When he confirms the home page change, it is switched back to weknow.ac....
I posted to find some other options. I have successfully removed this malware from Chrome by following the instructions posted in the forum so I am familiar with this malware. It's just the last step of changing the home page that isn't working. Are there other options? If not, I will have to create a new profile for this client.
I thought I would get some other options in this forum. I rely on MWB to protect Macs.
