"Windows Failed To Find Any Security Tool" shares many similarities with dozens of other fake errors such as Microsoft Windows Got De-Activated, Windows Health Is Critical, Windows Product Key Failure, and Microsoft Security Alert. Unlike "Windows Failed To Find Any Security Tool", most fake errors are displayed by malicious websites.

In any case, these viruses state that the system is damaged (e.g., infected, missing files, fake, etc.) - these claims are merely attempts to extort unsuspecting users. Users often visit these websites inadvertently - they are redirected by potentially unwanted programs (PUPs).

By offering various "useful features", PUPs attempt to give the impression of legitimacy and trick users to install, however, rather than giving any real value, they cause unwanted redirects, diminish system performance (by misusing resources to mine cryptocurrency or run other unwanted processes), gather information, and deliver malicious ads, thereby posing a threat to your privacy and Internet browsing safety. PUPs are designed only to generate revenue for the developers.

How did potentially unwanted programs install on my computer?

As mentioned above, "Windows Failed To Find Any Security Tool" is distributed as via installation set-ups. Research shows that various unofficial software distribution sources (e.g., free file hosting websites, freeware download websites, peer-to-peer [P2P] networks, etc.) often present malicious executables as legitimate software.

In doing so, criminals trick users into downloading and running malware. Essentially, the main reasons for computer infections are poor knowledge and careless behavior.

How to avoid installation of potentially unwanted applications?

To prevent this situation, be very cautious when browsing the Internet and especially when downloading/installing software. Malware is often distributed via 'malvertising' ads (e.g., coupons, banners, pop-ups, etc.) When clicked, these ads often redirect to malicious websites or even execute scripts that download/install malware.

In most cases, these ads appear legitimate, however, malicious ads are distinguishable for their redirects - most lead to survey, adult dating, pornography, gambling, and other dubious sites. As mentioned above, malicious ads are often displayed by potentially unwanted programs.

Therefore, if you encounter such ads, uninstall all suspicious applications and browser extensions. Note that malware is often "bundled" together with regular (mostly free) software. Developers hide "bundled" apps within various sections (e.g., the "Custom/Advanced" settings) of the download/installation processes.

Therefore, carefully analyze each window of the download/installation dialogues and opt-out of all additionally-included programs. In addition, we strongly advise you to download your software from official sources only and, if possible, using a direct download link. The key to computer safety is caution.
