Weknow.ac is a fake web search engine or in other words a malicious software. It is similar to chumsearch.com. It is essentially a program that can harm your device. It may look harmless but we know.ac records what you do online without your consent. On your device, weknow.ac is probably installed through a fake Adobe Flash update.
A fake Adobe Flash will put this fake search engine on your laptop or computer. It aims to harm Safari, Mozilla Firefox, and Google Chrome. The way it works is to hijack your browser settings and then to make your default search engine https://www.weknow.ac without you having a choice. Additionally, it will monitor your online searches.
These types of malware is designed in a way that anytime you try to change your default browser to your old one it changes the settings and goes back to the malware one. It almost makes it impossible to get rid of it. This has a big effect on the experience of the online user. Then, another even more serious effect is that your information is shared with third parties, potentially people who are up to no good. These people might use your information to make money. This means that having this software on your device puts you in danger of having your identity stolen.
If you get something like this installed on your Mac you must take immediate action to prevent it from causing harm. The way this usually happens is without you even knowing you did it. This marketing method is called “bundling”. Developers know that users often try to speed through download/installation processes and often skip steps.
In that way, all information regarding modification of browser settings is concealed within “Custom/Advanced” options (or some different sections) of the download/installation process. By going fast and skipping steps, many people make the mistake of allowing set-ups to make changes, thus exposing their systems to the dangers of various viruses and risking their privacy.
How do you prevent this? The answer is pretty easy, you just need to pay more attention and be more careful when installing programs on your computer. Read through every step and make sure you don’t allow additional changes or add ons with the program you are installing. Another tip is to only look for programs from sources that are known and official.
