What is AvastUI.exe?

The AvastUI.exe process is a software component of Avast Free Antivirus, a shareware or freeware security program that can be downloaded onto Windows and MacOS computers to protect against viruses and malware. AvastUI.exe launches the UI, or user interface, for Avast Free Antivirus and is generally effective in doing so. However, Windows 7 users in particular have faced issues with AvastUI.exe completing this process recently after installation or a new update. The next section will detail these issues that prompt the “AvastUI.exe – entry point not found” error to occur.

Causes of AvastUI.exe – Entry Point Not Found

There are a number of factors that could be influencing the AvastUI.exe process to fail. However, there are a few that are far more commonly reported causes that have particularly affected Windows 7 users. Before looking into these causes, you should first ensure that the AvastUI.exe file on your computer is not a virus or malware. Viruses and malware often camouflage themselves under the guise of an executable in order to infiltrate computers.

Go through the necessary investigative process, checking the file’s location, information, and spelling, to determine whether or not you are dealing with a virus. If you have determined that you are dealing with a virus, then Malwarebytes is an effective anti-virus tool for removing viruses and malware.
