Microsoft Font Pack Was Not Found Scam

Also Known As: "Microsoft Font Pack was not found" virus
Type: Adware
Damage level: Medium

What is Microsoft Font Pack Was Not Found?

Identical to Adobe Flash Player Was Not Found, "Microsoft Font Pack Was Not Found" is a fake error displayed by a malicious website.

Research shows that users are often redirected to this site by various potentially unwanted programs (PUPs). In most cases, these programs infiltrate systems without users’ permission. Furthermore, PUPs deliver intrusive advertisements, gather data, and also misuse system resources to run unnecessary background processes.

Microsoft Font Pack Was Not Found adware

The "Microsoft Font Pack Was Not Found" error states that the website that the user is trying to access cannot be loaded correctly, since the system is missing certain fonts. Users are then encouraged to download/update these missing fonts.

Bear in mind, however, that "Microsoft Font Pack Was Not Found" is fake and has nothing to do with Microsoft - it is designed by cyber criminals to proliferate malware. Rather than downloading updates, users will probably infect their systems. At time of research, "Microsoft Font Pack Was Not Found" was proliferating a password-stealing virus.

Previously, however, these scam campaigns were used to distribute adware and ransomware. In any case, never trust "Microsoft Font Pack Was Not Found" - it is a scam. Your software should be updated only using implemented functionality or tools provided by the official developers. Immediately leave this malicious website.

Note that some of these sites employ scripts that prevent users from closing tabs. Therefore, we recommend that you close the entire web browser (preferably, via Task Manager) or reboot the system. In addition, never click "Restore Closed Tabs" after re-running the web browser, as this will reopen the malicious website.

As mentioned above, potentially unwanted programs typically deliver various intrusive advertisements (coupons, banners, pop-ups, and so on). These are delivered using various tools that enable placement of third party graphical content on any site. Therefore, most displayed ads conceal underlying website content, thereby significantly diminishing the browsing experience.

Furthermore, displayed ads often redirect to malicious websites and even run scripts that download/install malware. Therefore, clicking them risks various computer infections. Another downside is information tracking. Potentially unwanted programs gather various data types, including personal details.

In addition, the data is typically sold to third parties (potentially, cyber criminals) who generate revenue by misusing personal information. The presence of information-tracking apps can lead to serious privacy issues or even identity theft.

Furthermore, potentially unwanted programs misuse system resources to perform various unnecessary tasks (e.g., mine cryptocurrencies) without users' consent. These programs significantly reduce overall system performance. For these reasons, all potentially unwanted programs must be eliminate immediately.

"Microsoft Font Pack Was Not Found" shares many similarities with Your Device Is Under Threat, Windows Support Alert, Google Security Warning, and dozens of other fake errors, however, unlike "Microsoft Font Pack Was Not Found", these errors do not promote downloads - they simply attempt to scare and trick victims into calling fake technical support and pay for services that are not required.

Potentially unwanted programs also share many similarities. Almost all offer "useful features", however, since their only purpose is to generate revenue for the developers, PUPs typically deliver no significant value and pose a direct threat to your privacy and Internet browsing safety.

How did potentially unwanted programs install on my computer?

Some PUPs are free for anyone to download on official websites, however, in most cases criminals proliferate them by employing a deceptive marketing method called "bundling" and the aforementioned intrusive advertisements. "Bundling" is stealth installation of rogue apps together with regular software/apps.

Developers are aware that many users rush download/installation processes and skip steps. Therefore, they hide "bundled" apps within "Custom/Advanced" settings. Skipping download/installation steps and clicking various advertisements, thus often leads to inadvertent installation of potentially unwanted programs.

How to avoid installation of potentially unwanted applications?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when downloading/installing software and browsing the Internet. Carefully analyze each step of the download/installation processes and opt-out of all additionally-included programs.

It is also highly recommended that you download your applications from official sources only and use direct download links. Third party downloaders/installers should never be used, since criminals monetize them by promoting rogue software (the "bundling" method).

Intrusive ads typically look legitimate, however, they are distinguishable since most lead to survey, gambling, adult dating, and other dubious websites. If you encounter such redirects, immediately eliminate all dubious applications and browser plug-ins.
