how to remove weknow.ac from safari

I was running Malwarebytes when my Mac got infected. Malwarebytes was able to quarantine it but that didn't fix the browser issue. Their customer service department was able to help out about how to fix the browser issue once the other files were quarantined. Here was their advice:

I contacted Apple Support Chat just now with an Advisor, and it was fairly simple to resolve.

1) First, search for Malwarebytes and download it (it's legitimate, don't worry!). Install it, and run "Scan".

2) After it's finished scanning, don't click anything on Malwarebytes yet. Clear all history and data on *all* of your web browsers. Check Extensions, too (e.g. click on upper left "Safari", on the drop-down menu click "Preferences", then go to "Extensions"), and make sure nothing on there is suspicious, or that you don't remember having installed.

3) Quit your web browsers, then click "Confirm", and Malwarebytes will remove the detected threats for you. Just to be sure, you can double check by scanning again, after it deletes the threats. It should say "Congratulations, all clear!" or something of that sort.

The best way to also check that it's really gone - and this is for Chrome users - is to check Chrome homepage and see if it still says "Search". I tried so many different methods before, but this time it really went away!

This was the homepage that I kept on getting:

Then I removed it from Safari and uninstalled Chrome because it wouldn't disappear of Chrome. But just today, my desktop showed me this and got me alerted:

After you scan on Malwarebytes, it should look something like this:

Good luck to everybody!!! If all else fails, make sure you contact Apple Support.

Eric, Ive downloaded the premium version of Malwarebytes and its not finding the virus. Its says my system is clean. So I dont know what to do at this point. And Ive looked for it in my computer and I cant seem to find where it is hiding

That does not work. I did each step. I got it removed from Safari, but it keeps returning to Chrome over and over. I have tried malwarebytes.... nothing. ComboCleaner... nothing. MacCleaner3 and nothing

Nothing works.

Please, what have I missed that my virus/malware scan detects nothing, yet my browser still is effected

This is where I was getting stuck. I removed everything and changed the default search engine, but each time I opened up a new tab it went to the malware version. Resetting in the general page solved that problem. Thanks!

its the same thing here for my clients Mac, he bought mac on my advise that it would never be effected with virus/trojans but now Mac is also not spared by internet threats. I tried all the steps available on internet and only could disable the searchengine hijacking on chrome/safari but the homepage is still stuck on weknow.ac search bar. No matter what, in libary/launchagents,agents,launchdaemons. Whichever is suspicious as per recent date modified, deleted all but nothing worked. Instead of creating a support case in Google chrome, I am doing it here because its Mac and it is applying the same settings on every browser installed.

The problem is that the weknow malware creates an alternate profile that will keep changing the search engine. I got this from Malwarebytes and it worked for me:

To remove this, open System Preferences, then click the Profiles icon. You should see either two or three different items listed. One of them appears to be legitimate, but the other two (they may be combined into one entry) are not. You can identify which is bad by looking at the information for each profile. The bad entry (or entries) will say "com.myshopcoupon" somewhere, and should also refer to "weknow.ac". Any such entries should be removed. Leave the profile that refers to "com.Infomaniak", as I believe that one is legitimate.

After removing the profile, you'll need to fix the home page settings.

I had tried removing profile and it was able to fix my search engine settings restore back to Google in chrome but its homepage which I am unable to figure out. Both Safari and Chrome homepage or on New Tab opens weknow.ac search bar page.

Neither of those links go anywhere. The shorter one goes to a search and on Yahoo which we don't use at all. The longer one I get this error message" 503 Service Temporarily Unavailable" and I have tried it on different browsers.

When I search for weknow on Google and try to follow the steps there is no trace of weknow on the computer.

We have spoken to 3 level 2 techs at Apple and even they are at a loss. Each time spending almost an hour on the phone. Again these were the level 2 techs, not level 1. We are at a complete loss at how to remove this virus which has taken over all of our browsers.

Please help.

Use the manual instructions. Do not download any programs except Malwarebytes.

weknow.ac uninstall mac

Im Having the same Issue from the same exact source. Hopefully someone has a fix for us.

I dont have manual instructions, IT seems ti have embedded its self even very well. I accidently downloaded another antivirus software that may have infected me more.

You are welcome.
