Defenderlab[.]xyz in detail

Defenderlab[.]xyz runs a fake system scan and then displays a fake virus alert, a pop-up message claiming that a computer is infected with five viruses. That deceptive message also states that personal data, banking information, and other sensitive information is at risk and urges visitors to start the McAfee antivirus to eliminate all threats.

McAfee antivirus is legitimate software developed by the McAfee company. This company never uses sites like defenderlab[.]xyz to promote its products. Defenderlab[.]xyz is operated by affiliates who aim to collect illegitimate commissions - they participate in an affiliate program allowing them to earn money after a product is purchased via their page.

Also, defenderlab[.]xyz wants to display notifications. Usually, notifications displayed by such pages promote various scams, shady apps, open malicious pages, etc. Thus, it is highly advisable not to agree to receive notifications from defenderlab[.]xyz or any similar page.

Websites of this type in general

Defenderlab[.]xyz and similar pages display deceptive content (mainly to trick visitors into clicking the "Allow" button or purchasing software). They get opened via various illegal movie streaming websites, torrent sites, and similar pages. Pretty often, they open other pages of this kind. Moreover, their notifications can open malicious sites.

Examples of similar websites are safetyremind[.]xyz, win-scan[.]com, and windows-hold[.]com.

How did defenderlab[.]xyz gain permission to deliver spam notifications?

Websites do not show notifications unless they are allowed to show them. This permission is granted by clicking the "Allow", "Allow Notifications", or a similar button displayed by a browser while visiting pages. Typically, sites like defenderlab[.]xyz display deceptive content to trick visitors into agreeing to receive notifications.

How to prevent deceptive sites from delivering spam notifications?

Do not click the "Allow" button while visiting suspicious websites. Click the "Block" (or "Block Notifications") button or close such pages when they ask for permission to show notifications. Remember that legitimate pages never state that clicking the "Allow" button is required to load a video, download a file, prove that you are not a robot, etc.

If you are receiving unwanted notifications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

How to avoid browser notification spam?

Internet users should be very skeptical when being asked to allow notifications. While this is a useful feature that allows you to receive timely news from websites you like, deceptive marketers frequently abuse it.

Only allow notifications from websites that you fully trust. For added security - use an anti-malware application with a real-time web browsing monitor to block shady websites that tries to trick you into allowing spam notifications. We recommend using Combo Cleaner Antivirus for Windows.
