How To Remove “The ArialText Font Was Not Found” Virus

Phrases “The ArialText font was not found” and “Microsoft Font Pack is not installed” belong to a deceptive malware advertising campaign which can lead to serious damage to your computer.

If you constantly see this popup appearing you are most likely infected with other malware. ArialText popups try to trick users into downloading suspicious files and installing them on their computers. Once installed they infect your system with various dangerous viruses including Cerber ransomware which encrypts your files and makes them unopenable.

You should never download the suggested files even though they might look like legitimate Windows components. Also, constant “font is not installed” popups mean that your computer is most likely already infected with other malware which you should remove as soon as possible.

We have an automatic removal tool provided below. It will not only clean up your system from this and any other infections but also protect it in the future.

 Manual Removal Instructions:

NB: Make sure you follow the manual removal guide carefully. Even if you remove the virus there are chances that it will come back later if your computer is not protected. This is why we recommend using the automatic removal and protection tool listed at the beginning of this page.

Step 1:

Remove any suspicious programs that might contain the adware.

Start by opening the Programs and Features window using the following method:

Hold Windows () key and click R key while holding.

Enter the following in the field:


Click OK.

You might have to wait a bit before the list of all programs is loaded as it displays a list of all programs installed on your PC.

We recommend sorting the programs by “Installed On” column (simply click on the column name in order to sort by this value).

Look for any recently installed suspicious programs that might contain the adware as a bundle or could be the adware itself. If you have never seen or used an app chances are that it is an unwanted software.


Uninstall all suspicious programs by right-clicking on them and choosing Uninstall…

Repeat this process until no more suspicious programs are left.

Step 2:

Check your hosts file for any suspicious IPs that could be inserted by the virus.

Press and hold Windows () key and click R key.

Go to the Startup tab and uncheck all suspicious entries.

The infected or fake startup items usually have “Unknown” listed as Manufacturer. However, sometimes they might pretend to be legitimate programs.

Then create them again in order to have clean browser start.

Alternatively, you can click Properties on each of the shortcuts and remove any additions (usually an url) made to the Target field by the virus.

After removing the virus

When you have finished removing the adware and reverting your browser settings make sure to protect your computer by installing a good antivirus suite that would identify the threats online and in programs you have downloaded. Also, never install suspicious programs. If you are installing a new software, make sure it has nothing bundled in it by following the install wizard as well as searching for user reviews online.
