Regularly updating your computer’s antivirus system is an integral part of maintaining your

Computer. The case is not any different if you are using the Avast antivirus software. Yet,

Users have faced some problems after updating to the latest Avast version.


Many users have been reporting that the Avast antivirus will not open after the recent

upgrade to the 18.4.2388 version. Every time Avast is not opening, the message ‘UI failed to

load’ is displayed. To lighten the scenario, the developers have even included a note

acknowledging the fact that the issue is embarrassing.


When this error occurs and the user cannot open Avast, two buttons are displayed on the

window. One of the buttons allows you to exit the application and the other is meant to restart

the Avast services.


In case you are going through a lucky day, the problem would be fixed by simply clicking the

restart services button. Yet, more often than not, the issue doesn’t simply vanish in that way.

That being said, you must also know that the fix to this Avast error is quite easy and it

doesn’t take much time to solve it.


As Avast has themselves notified its common users, the most probable cause for this problem

is an issue with the Windows Services settings and configurations.


The primary solution to solve the error is to re-install/repair the antivirus. Yet, before that can

be done, some other factors need to be ensured and some changes have to be made to the

Windows settings.
