What are aswEngSrv.exe Error Messages?


aswEngSrv.exe Runtime Errors

Runtime errors are Avast Internet Security errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when aswEngSrv.exe is attempted to be loaded either when Avast Internet Security is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using Avast Internet Security.

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

Some of the most common aswEngSrv.exe errors include:

  • aswEngSrv.exe - Bad Image.
  • aswEngSrv.exe Application Error.
  • aswEngSrv.exe could not be found.

Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Finding the source of the aswEngSrv.exe error is key to properly resolving these errors. Although most of these EXE errors affecting aswEngSrv.exe will happen during startup, occasionally you will encounter a runtime error while using Avast Antivirus. This can occur due to poor programming on behalf of AVAST Software, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of aswEngSrv.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
