Update of database / Desinstallation

Hi
Everyday the program tries tu update database (Viruses) but it doesn’t find them.
I try to desinstall avast (with avast cleanup utility too) but it doesn’t work.
What can I do?

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

I am unsing Avast free antivirus 19.4.2374 (Version 19.3.4241.0)
Windows 10 64 version 1803
No other security software installed, no one as avast used before

Update to the latest version (19.5.2378): https://forum.avast.com/index.php?topic=227342.0
