Did you send the file to sedina@asw.cz ?
This seems to be a bug…
As I can see from your posted pictures…
Sometimes with eicar.com test files the ‘delete’ function only works if you send the file to Recycle bin. Maybe the bug prevents the deletion the file because it is in use (by Outlook) but I’m not sure.
Does avast deleted other infected files?, as techie asked you
Did you perform a complet scan in your system after the infection and before the email deletion? What were the results?
