application unable to start
« on: March 02, 2018, 12:39:44 PM »
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?

- 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.
