Mydesktopdefender.com is a suspicious domain that may trigger numerous redirects, based on the user’s geographical location. Such websites are often associated with the generation of unwanted ads, hence the term adware is often added to their description. Most antivirus and anti-malware products may detect pages like Mydesktopdefender.com as PUPs and adware, for instance Adware.Generic and PUA.Generic.
Also note that Mydesktopdefender.com could be associated with tech support scammers. These threat actors could deploy numerous such pages in their attempts to make potential victims install suspicious software on their machines. Examples include SilverSpeedup, MacFly, Xbits, etc. Both macOS and Windows users can be targeted by such rogue applications.
Also, keep in mind that a fake AV program may also act like a browser hijacker and take over your browsers. If you notice that your browser’s homepage has been replaced with the ‘official’ page of a suspicious security product, be sure that you have rogue AV and (quite possibly) other malware draining your system. You can read more about fake programs in our article dedicated to the detection and removal of rogue programs.

Mydesktopdefender.com More Details
As a result of interacting with Mydesktopdefender.com, you can start experiencing intrusive pop-up ads, which are often entirely unrelated to your browsing. These ads could contain information about other questionable applications and detected system issues, or push notifications. Keep in mind that your searches could also be redirected to unwanted and suspicious pages.
Pages such as Mydesktopdefender.com are often associated with adware and browser hijacking apps, known to collect various details about your browsing:
- Visited URLs and websites
- Browser’s home page
- Search queries
- Search queries on the visited web pages
- Type of used browser
- Operating system type
- Internet protocol (IP) address
- Geographic location

To avoid the installation of unwanted programs that may cause the appearance of Mydesktopdefender.com in your browser, you should play close attention during the installation of freeware apps. Freeware you recently downloaded from software download pages could have been bundled with OfferCore. Third-party developers may support shady practices for monetization purposes, and may offer you to change your homepage or search provider. You can decline any of these additional offers only if you are careful enough to spot them during installation. In other words, paying attention to the installation setups of freeware could spare you from having to deal with various unwanted downloads.
Note. Suspicious sites such as Mydesktopdefender.com can be advertised as repositories of cracked legitimate software packages. Files delivered in such malicious campaigns can be masqueraded as droppers, as seen in a recent example analyzed by Sophos researchers. If the potential victim clicks on a link to download such a file, they could get through a set of redirector JavaScripts. Then, the victim is sent to one of multiple download locations that deliver various versions of the dropper. This particular campaign was distributing various types of malware, including STOP ransomware.
