What is "The PT Sans Font Wasn't Found"?

Similar to "Chrome Update Center" and many others, "The PT Sans Font Wasn't Found" is a fake error message displayed by various malicious websites. Users typically visit these websites inadvertently - they are redirected by potentially unwanted applications (PUAs) already present on the system or intrusive advertisements delivered by other rogue sites. PUAs usually infiltrate computers without users' consent and are designed to deliver intrusive advertisements and record sensitive data. Note: "The PT Sans Font Wasn't Found" scam is used to spread the TrickBot trojan.

The PT Sans Font Wasn't Found scam message

"The PT Sans Font Wasn't Found" displays a fake error message stating that the system is missing a font called "PT Sans". The message encourages visitors to download this font immediately, otherwise content will not be displayed properly. In fact, rather than downloading a font, users end up downloading and installing a high-risk trojan called TrickBot. Furthermore, the error text differs slightly depending on the browser used. Although TrickBot has been updated a number of times, its main purpose remains identical: to record sensitive data. One TrickBot feature is modification of visited websites - it changes them so that entered logins/passwords are immediately saved to a remote server. This malware is also capable of stealing browser cookies, saved logins/passwords in browsers and in various applications. Other account-related data is also collected and saved to a server. Cyber criminals aim to generate as much revenue as possible. Therefore, having a data-tracking trojan installed on your computer can have serious consequences. Cyber criminals might gain access to victims' bank accounts and steal savings. Furthermore, they can steal email, social network, and other personal accounts, which can lead to identity theft. Therefore, TrickBot poses a significant threat to your privacy and should be eliminated immediately. We strongly recommend that you ignore "The PT Sans Font Wasn't Found" error message and never download any files from websites that display this or other similar messages.

As mentioned above, users are often redirected to websites that deliver "The PT Sans Font Wasn't Found" message by various PUAs. As well as causing redirects, these applications are also likely to deliver coupons, banners, pop-ups, and other similar intrusive advertisements. These usually redirect to dubious websites and might even run scripts that download/install other PUAs. Therefore, even a single accidental click can result in high-risk computer infections. PUAs are also likely to record user-system information. In this case, however, collected data is less sensitive - the list typically includes IP addresses, website URLs visited, web pages viewed, search queries, IP addresses, geolocations, and so on. The data is later shared with third parties (potentially, cyber criminals) who misuse it to generate revenue. Therefore, data tracking can lead to privacy issues. As with TrickBot, all potentially unwanted applications should be immediately removed.

There are dozens of fake error messages displayed by deceptive websites. Most claim that the system is damaged, however, not all proliferate high-risk trojans such as TrickBot. Most fake error messages encourage users to contact fake 'tech support' or to download fake system cleaners (both of which require payment). In any case, trusting fake error messages can lead to financial loss and privacy issues.

How did "The PT Sans Font Wasn't Found" infect my computer?

As mentioned above, "The PT Sans Font Wasn't Found" encourages users to download a font, which is supposedly missing. The font supposedly allows website content to be displayed properly. In fact, the downloaded file is malicious and downloading/running it leads to infiltration of the TrickBot trojan. Criminals often present malware as legitimate software. In most cases, they use this method when proliferating malware through various unofficial download sources (e.g., Peer-to-Peer [P2P] networks, freeware download websites, free file hosting sites, and similar).

How to avoid installation of malware?

The main reasons for computer infections are poor knowledge of these threats and careless behavior. The key to safety is caution. Therefore, pay attention during the download/installation processes. Never trust error messages displayed on dubious sites. Software/operating systems should be updated only through implemented functions or tools provided by the official developers. The same applies to software downloads. Your programs should be downloaded from official sources only, preferably using direct download links. Third party downloaders/installers often include rogue apps and, thus, these tools should never be used. While downloading/installing, carefully analyze each window of the download/installation dialogs using the "Custom" or "Advanced" settings. Opt-out of all additionally-included programs and decline offers to download/install them. The aforementioned intrusive advertisements usually seem legitimate. Once clicked, however, they redirect to dubious websites (gambling, adult dating, pornography, and similar). If you experience these ads/redirects, eliminate all suspicious applications and browser plug-ins. If you have already opened "The PT Sans Font Wasn't Found" attachment, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer.
