Avast UI Failed to Load: 4 Steps to Fixed it

Multiple active shields, nicknamed Core Shields, are used by Avast Antivirus to safeguard your computer from dangerous attacks in real-time. However, you occasionally need to use the Avast user interface (UI). It not only allows you to do thorough scans for hidden viruses, but it also allows you to customize how the antivirus program works.

However, the Avast Antivirus UI in Windows 10 can occasionally fail to load. Instead, you might get an error notice that says “UI failed to load.” Other problems you can notice include “Sorry, our screen didn’t load” and “Well, this is embarrassing.” The error message may include a Restart Services option, but selecting it usually has no effect.

As we all know, Windows 10 is still susceptible to viruses, malware, spyware, and other malicious software. Thankfully, antivirus software with a lot of features, like Avast, can help users protect their computers from malware.


Due to problems with Windows 10’s Remote Desktop Services, the Avast UI frequently fails to launch. Reconfiguring the functionality should, in most situations, allow the user interface to load appropriately. If this isn’t the case, you’ll have to update, patch, or reinstall Avast.
