How to Remove WINDOWSDEFENDER.SITE (Chrome/Edge/Firefox) | Updated

I wrote this article to help you remove WINDOWSDEFENDER.SITE. This WINDOWSDEFENDER.SITE removal guide works for Chrome, Firefox and Internet Explorer.

The WINDOWSDEFENDER.SITE page is bad news for your system. Seeing and landing on it all the time is a sign of an infection. An adware infection, to be exact. As you know, adware pests are very deceptive and sneaky. Do not trust them. And, the one you are stuck with is no exception. The WINDOWSDEFENDER.SITE contains a malicious script which prevents you from closing it. This means that if you get redirected to the site, you will not be able to exit without agreeing to some extension being downloaded first of something like that. Do not, under any circumstances, give your consent to anything this page wants. It is dangerous. Close it with the help of your Task Manager and start a new browsing session.

As we said, the WINDOWSDEFENDER.SITE page indicates that there is an adware infection in your system and instead of downloading more malicious extensions you must be focused on removing the adware from your machine. Adware pests don’t make for pleasant tenants. They are irritating and intrusive. The more time this threat stays in your system, the more problems you will be forced to face. Do not procrastinate. Delete the adware as soon as possible.

Once in your system, the pest doesn’t waste time. It injects all of your previously reliable browsers with tons of commercials. And not any kind of commercials. The adware does its homework before the ad bombardment. It studies you in order to learn what you like and what you are interested in. Then, it uses this information to create ads which you will like and find appealing. Why? It is not because it wants to enhance your online shopping or browsing experience. Of course, not. It has its own agenda. The adware needs your click. It is created to boost web traffic to particular sites, thus generating pay-per-click revenue for its owners. That’s why it needs you to click on the adverts it shows you. For each of your click, the hackers get paid. You are becoming their sponsor. But that’s not all.

Be extra careful. Nothing the adware displays can be trusted. It doesn’t care about your safety. It just displays ads that will spark your interest so you would click. The ads, however, are not verified. What is more, most of them are even corrupted or misleading or both. If you accidentally click on the wrong ad, you may worsen your predicament by downloading more pests on board. Do not trust the commercials. If an offer looks too good to be true, it probably isn’t. Don’t make the mistake of clicking. Do your best to get rid of the advertisements. The only way to do that is to remove the adware itself. Otherwise, it will become more and more aggressive with each passing day and will bombard you with even more adverts. Don’t waste your time. Follow our removal guide below and get rid of the intruder for good. This is the best course of action you can take.

How did you get infected with the adware? Pests like this usually travel bundles with other programs which you download off of the web. However, if you rush the installation and skip the Terms and Conditions, you cannot notice the extra apps that are attached to the bundle so they enter your system undisturbed. In order to prevent that, always opt for the Advanced settings in the Setup Wizard. They take more time but also give you complete control over the installation process. You are able to see all extras and deselect them before finishing installing the program you originally wanted. Do that next time you download something. Do your due diligence. It is the only way to keep your PC safe.
