Weknow.ac is a browser hijacker that it will change the homepage and search engine for your web browser to http://weknow.ac.

Weknow.ac Redirect MacOS Virus

The Weknow.ac redirect is caused by a browser hijacker which is installed by the users, whether that is knowingly or not. Often, this type of program is offered through advertisements or bundled with other software, leaving the user puzzled where this software came from.
Browser hijackers are a type of malware created for the purpose of modifying Internet browser settings without the user’s knowledge or consent.

When the Weknow.ac browser hijacker is installed on a PC, common symptoms include:

  • Changing the web browser’s default homepage to Weknow.ac
  • Changing the browser’s search provider, built-in search box to http://weknow.ac
  • Ability to modify the ‘new tab’ functionality to launch the modified search portal page
  • Loads into the web browser via an extension or add-on
You should always pay attention when installing software because often, a software installer includes optional installs, such as this Weknow.ac browser hijacker. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.

How to Stay Safe Online

Here are 10 basic security tips to help you avoid malware and protect your device:

  1. Use a good antivirus and keep it up-to-date.

    Shield Guide

    It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.

  2. Keep software and operating systems up-to-date.

    updates-guide

    Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

  3. Be careful when installing programs and apps.

    install guide

    Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

  4. Install an ad blocker.

    Ad Blocker

    Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

  5. Be careful what you download.

    Trojan Horse

    A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

  6. Be alert for people trying to trick you.

    warning sign

    Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

  7. Back up your data.
