Content Defender. How to remove? (Uninstall guide)

removal by Ugnius Kiguolis - - | Type: Adware

Is Content Defender worth installing?

Content Defender by Artex Management S.A. is a browser extension that bears the signature of YUNITEKH SOFT. On the initial inspection, it may look like a legitimate application that might “protect your PC against unwanted and malicious content.” However, security experts placed it to the ‘adware’ and ‘potentially unwanted program’ (PUP) lists of computer infections. The first suspicious thing is the absence of a download button on its official website. This should be a helpful tip allowing people to decide about the reliability of the program. No matter how it manages to enter PC’s system, instead of an increased amount of security scans that people may expect a PC protection tool to be doing, you may notice an increased amount of commercial advertisements on Mozilla Firefox, Internet Explorer or Google Chrome. This adware may flood you will deadly annoying pop-up and banner ads, which may be linked to predetermined websites that seek to increase page rank or sales. While some of these websites might be safe enough for you to land on, there is no way of knowing whether all of them are like that. Thus, you should better keep the distance from the Content Defender ads that are usually distinguished from the others by a slogan “Ads by Content Defender.” What is more, we would advise you to keep this adware away from your computer because it installs cookies on browsers and accumulates/stores browsing-related information about its users, so you are not an exception. In order to stop data from leakage and misleading content from emerging during your browsing, it’s advisable NOT to install such and similar apps. In case you have already installed it, you have one reasonable solution – remove Content Defender virus using some reliable anti-spyware tool like Reimage.

How can Content Defender infect my web browser?

First of all, your web browser may be infected with Content Defender right after you download this tool reasonably believing that it will protect you from landing on malicious websites. However, most the users did not install it manually. This adware has been installed on their computers by default along with another freeware. Such distribution method, namely ‘bundling’, means that some free program you have probably downloaded has been bundled with some third-party apps and Content Defender has been one of them. Therefore, if you want to avoid such unpleasant surprises, you should always monitor each step of the installation process and deselect everything that you might consider unsuitable to end up on your computer.

How can I get rid of Content Defender PUP?

Despite all the downsides, Content Defender is a legitimate application. It means that you can quite easily uninstall it by yourself. However, we highly do not recommend this. Not only due to the fact that we strongly approve of using anti-spyware tools for system maintenance. Keep in mind that Content Defender redirects and ads may be just a peak of an iceberg, As we have already mentioned, this adware is usually spread via software packages, what means that other potentially unwanted programs might have also slithered onto your computer. Therefore, the best that you can do it do initiate a full system check with reliable anti-spyware and ensure a complete system maintenance.

You can remove virus damage automatically with a help of one of these programs: Reimage, Malwarebytes. We recommend these applications because they detect potentially unwanted programs and viruses with all their files and registry entries that are related to them.
