application unable to start

Every time I switch on my computer or when I try to open Avast through the icon on my desk top I get this message ’ The application was unable to start correctly (0xc0000005) Click Ok to close the application.
The title is avastui.exe-Application Error
When I go on line and look at my Avast account it tells me everything on Avast is running fine. Any ideas what this is all about?

Update to the latest version (18.2.2328): https://forum.avast.com/index.php?topic=216700.0

I’ve done that now but still getting that same message .

  • Which Avast…? (Free/Pro/IS/Premier)
  • OS…? (32/64 Bit…? - which SP/Build…?)
  • Other security related software installed…?
  • Which AV(s) did you use before Avast…?

Free Avast and clean up
64 bit
windows 7
no other AV installed and not had any before Avast.
When I look at my account it appears everything is running and protected - would that be right?

  1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe
  2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions…!!)
  3. Reinstall Avast with the downloaded installer from point 1.
  4. Reboot.

Thankyou. All seems to be sorted now. Appreciate the help. :slight_smile:

You’re welcome.
