Mcls.xyz

Mcls.xyz is a website whose homepage displays a basic search engine that redirects its users to a legitimate and popular Russian Web search service. However, upon further analysis of URLs linked to Mcls.xyz, cybersecurity experts uncovered a series of pages that appear to display fake 'Adobe Flash Update' prompts whose purpose may be to trick users into downloading a Potentially Unwanted Program (PUP) or other dubious utilities. Fake Adobe Flash Player updates are one of the most popular contents that cybercriminals and online con artists use to disguise potentially harmful downloads, and we advise you to be extra careful when you encounter content like this.

Seeing Mcls.xyz in your Web browser is not a symptom of a malware or adware infection – you may stumble upon this page while browsing other low-quality sites such as the ones linked to the propagation of pirated media and software. You should not forget that shady websites often work with equally shady advertising networks, and browsing low-ranked websites may often expose you to content like the one found on Mcls.xyz.

If the Mcls.xyz's pop-ups are appearing in your Web browser, you should ignore their contents, and remember not to download any of the files they promote. It is also recommended to run a reputable anti-virus product that can ensure that you did not end up with any unwanted software on your computer.
