Get rid of weknow.ac redirect for my search engines1 Recommended Answer
Save these instructions somewhere safe and close all open Google Chrome windows.
Scan your computer for the unwanted software using recommended removal software: Malwarebytes.
- Open a new Terminal window. (Tell me how).
- Enter the following commands, pressing enter after each line:
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
Thanks for reaching out to the Google Chrome Help Forum.
Could you please let me know if you've followed the steps given in this help article to set your default search engine. Whenever your startup page, homepage, or search engine is suddenly changed or being redirected or if you are unable to change it, then there´s a possibility that you have unwanted software on your device. So, to make sure we eliminate malware from the scenario, please follow the steps given in this help article.
Also, could you please let me know if this happens in the Incognito Mode as well? If that works fine, then temporarily disable your extensions to identify which one is causing the problem. To do this go to chrome://extensions and uncheck Enabled for each extension one by one.
If that doesn't help, reset Chrome settings and see if that works for you. (Your saved bookmarks and passwords won't be cleared or changed.) If the issue still persists, I’d suggest you to create a new user profile by adding a new user on Chrome.
Let me know how it goes.
Hi - I'm having the same issue: I downloaded the malware weknow.ac and have 1) permanently deleted all the bad applications, 2) removed any extensions, 3) paid Reimagine scanner to clean up any remaining malware, Reset to default settings. Still, weknow.ac is the default search engine and it disallows removing it. I've attached 3 screenshots. What else is there left to do, Google? PLEASE HELP!
step 4: You'd be able to delete the chum search from your Chrome's "Manage search engine" setting@ chrome://settings/searchEngines.
Step 5: scan yr macOS with Malwarebytes Antimalware + Avast Security for Mac.
Step 6: PLZ HELP report that webknow .ac to to Google SafeBrowsing Team here.
