Fix: AVG Installation Error Event exec_finished

An antivirus program is one of the most important programs on your computer responsible for preventing cyber attacks and securing system against malwares, viruses and adwares. The virus can infect your system in a number ways therefore it is important that you have an active antivirus software always running. Unfortunately, users running AVG when they try and install it for the first time or when they upgrade AVG are sometimes populated with the exec_finished error.

The most common reason for this error to occur is when another antivirus software conflicts with AVG or when you’ve already had AVG installed before and the new install/upgrade conflicts.


In this guide, we aim to resolve the exec_finished issue. You should only run one antivirus software, if you are running other softwares such as McAfee, Norton or BitDefender/aVast then they must be installed.

You can do this by Holding the Windows Key and Pressing R simultaneously to open run dialog,and in there type appwiz.cpl and Click OK.


Go through the list of installed programs, and uninstall all the antivirus softwares including previously installed AVG variations.
