What kind of page is mydesktopdefence[.]com?

Mydesktopdefence[.]com overview

How rogue webpages operate is determined by their visitors' IP addresses/ geolocations. For example, mydesktopdefence[.]com has been observed running the "McAfee - Your PC is infected with 5 viruses!" scam.

Sites display browser notifications with user permission, which also applies to mydesktopdefence[.]com. Hence, if tricked by this page into doing so - it will display notifications/advertisements. The delivered ads promote untrustworthy websites, apps, and even scams. The adverts might endorse legitimate content - however, this marketing technique is not used by its developers/creators but by various affiliates.

Browser notification spam in general

Investmentstar.orggoodcaptchastyle.toppayments4u.org, and bruperchrophone.com are some examples of webpages similar to mydesktopdefence[.]com. Notifications displayed by these rogue sites are used in a wide variety of affiliate programs. Affiliates behind the websites can promote legitimate software/products to acquire illegitimate commissions.

How did mydesktopdefence[.]com gain permission to deliver spam notifications?

Sites need user permission to display browser notifications. Rogue webpages often employ deceptive content (e.g., fake CAPTCHA verification, clickbait, etc.) to lure visitors into enabling their notifications (i.e., clicking "Allow", "Allow Notifications", etc.).

How to prevent deceptive sites from delivering spam notifications?

To avoid seeing unwanted browser notifications/ advertisements, websites must not be enabled to display them. In other words, the "Allow", "Allow Notifications", and similar buttons must not be clicked. Therefore, when an untrustworthy website is accessed, the notification requests have to be either ignored or declined (i.e., "Block", "Block Notifications", etc. pressed).

It is noteworthy that if a browser is force-opening questionable sites (e.g., mydesktopdefence[.]com) - this can be due to adware installed onto the system. If your computer is already infected with rogue applications, 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.
