Tool Extension Virus

Tool Extension

If your computer has been infected by a program called Tool Extension, you have landed yourself what is popularly referred to as a browser hijacker. Tool Extension integrates with widely used web browsers such as Firefox, Chrome and Edge and spams them with online ads.

The ads can come in every shape and size ranging from screen-wide banners and blinking box messages to annoying popups that come out of nowhere and beyond. And don’t rely on your ad blocker or other such tool to stop them. Thanks to Tool Extension, these ads are generated from within your own system, hence no popup blocker will be able to prevent them from showing up on your screen.

This is also valid for the sudden page redirects that you may have started experiencing ever since Tool Extension appeared on your computer. These can take place at any point during your browsing sessions and will force you to land on a variety of different sponsored web locations. Typically, these will be sites that are trying to promote and/or sell some type of product or service. And as for the page redirects themselves, they may take place within the same tab, or they may open new ones, and sometimes they may even open new browser windows.

The Tool Extension Virus

Aside from the advertising materials that software like the Tool Extension virus can generate in your browser, these type of applications are also known for their ability to meddle with the browser’s settings. This is actually how hijackers such as the Tool extension virus get their name. And most vividly this is seen in the changes they tend to make to the browser’s homepage as well as to the default search engine.

But what has a tendency to shock users is when they try and revert these setting and reconfigure their browser so that it has the old settings again. As soon as they restart their browsing program, the hijacker will have reinstated its own configurations and that will be that. Thus, unless you thoroughly remove Tool Extension or Editor Extension without leaving any residual components, you won’t be able to restore your browser to its pre-hijacker state.

That is why we have designed the below removal guide. With its help, you will be able to completely uninstall this browser hijacker and resume an ad-free browsing experience without the annoying page redirects and other effects. And if you would rather have the removal process handled automatically, we also have a professional removal tool available for you on this page.

Keep in mind that removing Tool Extension isn’t just doing yourself a favor in terms of the irritation and frustration you will be saving yourself. It’s actually beneficial to the overall safety of your system because there’s a certain risk associated with these types of programs. Namely, as a result of their endless ads and redirects, there’s a danger of landing on compromised web locations that could potentially be harboring viruses and different malicious code. So if you’d rather avoid the risk of getting infected by some ransomware or Trojan horse virus, removing Tool Extension is certainly the way to go.

• HKEY_CURRENT_USER—-Software—–Random Directory.
• HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
• HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

Look for folders and subfolders with strange-sounding names in each of the directories listed above. You must use extreme caution while removing any files or directories associated with Tool Extension.

Attention! When in doubt about which registry files and folders are linked to the browser hijacker, better leave them there and don’t make any changes, as deleting a legitimate entry may corrupt your OS.
