What are Avira.WebAppHost.exe Error Messages?

Runtime errors are the most common form of EXE error you will encounter using Avira Free Antivirus.

In most cases, Avira.WebAppHost.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these Avira.WebAppHost.exe error messages mean that Avira Free Antivirus was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Avira Free Antivirus will be unable to start without resolving these errors.
