What is Defender-scan.xyz ads?

Defender-scan.xyz is a malicious website that tries to trick users to download

Defender-scan.xyzDefender-scan.xyz is a fake website you shouldn't trust

Defender-scan.xyz is just one of the thousands of websites that have recently been imitating McAfee or Norton antivirus scans. Visitors are told that viruses have been found on their devices and that security software needs to be installed in order to remediate the situation. In reality, these security companies have nothing to do with the promoted message, and it is entirely fake – produced by malicious actors who want to profit from the pay-per-install scheme.

In fact, there is no guarantee that the software downloaded from Defender-scan.xyz is even legitimate. It might be fake, which would result in your system compromise due to potentially unwanted program or malware installation. Under no circumstances install the promoted applications via this scam site.

It is also worth mentioning that redirects to Defender-scan.xyz and similar phishing websites could indicate the presence of adware[1] or even malware on your system. This also comes along with increased ad activity, which can be spotted as pop-ups, banners, flashing windows, auto-play videos, etc. Thus, we recommend checking the device for infections regardless of whether you installed the fake security software or not.

Scam message example

Users mostly enter a malicious website after they click a booby-trapped link. Torrents, X-rated, illegal video streaming, and similar high-risk websites are among the most common reasons for redirects to potentially dangerous places. Since the circumstances users get to Defender-scan.xyz are rather unexpected, many users might be caught off guard, and that's precisely what scammers are counting on.

Right after entering the page, users would be presented with what looks like a virus scan being performed by McAfee security software. It would soon claim that the system was infected with five viruses and needs to be cleaned immediately. It is also implied that the security software license has expired and needs to be renewed in order to proceed.

After clicking the “Renew Licence,” users are then rerouted to a website where they are asked to purchase security software. Please disregard these requests, as they might link you to malware download links. If you have installed unknown software, make sure you follow the instructions below to remove it effectively.

Remove potentially unwanted programs

Keep in mind that the Defender-scan.xyz virus scan results are always fake – whatever is displayed is fabricated (even the names of malware are not genuine). Even when disregarding these fake results, it would be a good idea to check the system for infections, as there could be adware or malware involved.

You can check your system manually, as we explain below, although we strongly recommend also scanning the device with SpyHunter 5Combo Cleaner, Malwarebytes, or another powerful anti-malware software.

We recommend first checking the “Extensions” section of your browser and removing all the apps if you aren't completely sure which one is causing trouble. Then you should find and remove unwanted programs installed on the system level:

Windows

  • Enter Control Panel into the Windows search box and hit Enter or click on the search result.
  • Under Programs, select Uninstall a program.Uninstall from Windows 1
  • From the list, find the entry of the suspicious program.
  • Right-click on the application and select Uninstall.
  • If User Account Control shows up, click Yes.
  • Wait till uninstallation process is complete and click OK.Uninstall from Windows 2

Mac

While moving apps into Trash is how you delete most normal applications, adware tends to create additional files for persistence. Thus, you should look for .plist and other files that could be related to the virus. If you are not sure, skip this step entirely.

  1. From the menu bar, select Go > Applications.
  2. In the Applications folder, look for all related entries.
  3. Click on the app and drag it to Trash (or right-click and pick Move to Trash)Uninstall from Mac 1

To fully remove an unwanted app, you need to access Application Support, LaunchAgents, and LaunchDaemons folders and delete relevant files:

  1. Select Go > Go to Folder.
  2. Enter /Library/Application Support and click Go or press Enter.
  3. In the Application Support folder, look for any dubious entries and then delete them.
  4. Now enter /Library/LaunchAgents and /Library/LaunchDaemons folders the same way and terminate all the related .plist files.

Stop data tracking

Cleaning your browsers is especially important after potentially unwanted/malicious software removal. When you visit websites and enter your passwords or other login details, these preferences are saved in the form of cookies. These tiny files may remain on your local machine until they are removed, all while being used to track information about you.

Passwords and other personal details are encrypted and can not be identified via cookies. However, a dangerous cyberattack known as cookie hijacking might allow cybercriminals to enter your accounts without trouble. Cleaning web browser caches[2] regularly can reduce this probability. We recommend employing ReimageIntego repair and maintenance utility instead if you would rather avoid doing this manually.

  • Under Privacy and security, select Clear browsing data.
  • Select Browsing history, Cookies and other site data, as well as Cached images and files.

Remove push notifications

Phishing[3] websites like Defender-scan.xyz often ask visitors to enable push notifications right after they enter the page. It is yet another way for them to benefit from advertisements, as those who agree would later be exposed to frequent pop-ups shown directly on desktops.

The contents of these push notifications would almost always be misleading or malicious, where users would be told that their systems are infected or that they have won an expensive gift. Please do not interact with these messages, as you may end up installing malware on your system, disclosing your personal data to cybercriminals, or spending money on useless services. In order to remove these pop-ups, follow the steps below.

How to prevent from getting adware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

 

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
