removal by Lucia Danes - - | Type: Adware

Help! I think my computer is infected. I cannot use my Internet browser normally anymore! Whenever I open the browser, I see this web page that claims to be related to “Windows Network Defender.” It displays me a message, saying: “Your browsing activity has been restricted. Your system was infected with critical spyware/malware/trojans.” What is this? Is it true? I have an anti-virus program, and it did not detect any virus on my computer. Please explain what is going on!

Why did Windows Network Defender hijack my computer?

Windows Network Defender is a nasty adware program, which can attack your computer without your knowledge. Usually, programs like Windows Network Defender adware can get into computer system together with other legitimate free programs. Think about it – do you pay enough attention to the installation setup when you install software on your system? Do you closely follow each installation step and read all the information provided? If you tend to skip reading the Terms of Use document, or if you rely on the traditional standard/basic/default installation option, then there is no hesitation why Windows Network Defender app has slithered to your computer seamlessly.

Windows Network Defender adware displaying Windows Network Defender ads

The problem is that the company that develops the Windows Network Defender fake support scam related apps tends to spread these potentially unwanted programs (PUPs) via bundling method. Bundling means grouping two or more programs into one, and presenting such pack as one file. This distribution method helps to promote potentially unwanted apps because the agreements to install them are usually being concealed under the Default/Standard/Basic installation settings. Instead of choosing these options, you should opt for Advanced or Custom one and deselect these agreements.
