Title: Avast 17 : can't open user interface!
Post by: REDACTED on February 09, 2017, 02:15:17 PM
Hi,

Just updated Avast to v17. But now can't open user interface : it opens then close immediately! In addition in the windows 10 taskbar icons are added. In 2 hours, there are near 15 Avast icons added... Then when we put the mouse pointer on it, it disapear then only one remains.

Any problem with v17?... (I already have rebooted the computer)

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.

Ok, thanks. There is no safe mode with Windows 10. I launch it in normal mode?

Launch the uninstaller, he'll offer to start/run in safe mode.
