Weknow.ac adware

What is Weknow.ac. Removal reasons and methods

Web-criminals, or whoever maintains Weknow.ac, want to make it as annoying as possible, to make you click on banners. By making this, you get new viruses to your computer. The method is easy. Weknow.ac simply shows a plenty of links, ads, banners and pop-ups, and as they appear right in front of user's face, he wants to close them. Unfortunately, these banners cannot be folded. They do not support the “hide” key, so any click launches another tab or a new window with a viral website. It also could initiate a download of a viral file, and if the system is already contaminated and the browser settings are changed – it will be successful. You get that very annoying viruses while Weknow.ac functions in the system.

 

 

 

To understand how the computer became infected, you have to figure out how adware penetrates the PC. The reason for it is the sponsored download. It surely is the safest technique to get into anyone’s laptop. Scammers just upload their viral folder on a few portals and temporize, until user downloads it. When it happens, it’s a matter of chance, so hackers might only expect that the operator doesn't like to dig through the EULA and won’t bother to find out what he’s actually installing. If you want to avoid the penetration trough sponsored installation – here are the hints that might be useful:

 

  • Take notice of the user agreement;
  • Do not install software, which hide their objectives;
  • In any case, do not deactivate your antivirus, even if you see a suggestion to;
  • Try to refrain from using unlicensed software;

 

Now, when you've mastered the basic regulations of PC security, let us explain how Weknow.ac works, for you to understand the manners to eliminate it.

 

When the defense was broken, Weknow.ac became very busy, which comes with creating new registry entries, changing the capabilities of browser shortcuts, modifying the browser settings and scheduling tasks. We don’t claim that the procedure is always the same, but your browser controls are the first priority for an adware, to ensure that your device is fragile. Usually, adware changes the homepage and the search engine controls, placing there a lame website in place of reliable services. When you use it for Internet-surfing – you expose the PC to the jeopardy of being infected one more time. Some advertising tools might develop scheduled tasks for reinstallation after you delete them. This function makes it problematic to remove them entirely. You can struggle to do it repeatedly, removing suspicious files and folders, but when you reboot the PC Weknow.ac will be already there. To elude this you need to run a more scrutinous scanning or take advantage of a decent anti-viral program.

Step 4. Scan MAC with anti-malware

To eliminate this virus you should pick one of two common variants: manual and automatic. They both have some pros and cons, and one of them may look much better for your purposes than another one. The highly significant advantage of hand uninstalling is that you can do it on your own, and there is no necessity to purchase any additional tools. The cons are that you can’t eliminate the serious viruses are too hard to uninstall by hand. You also have to have a certain scale of PC literacy to effectively execute this manner. Another manner needs you to download an antivirus, and since that moment, the Weknow.ac problems will end.
