Can anyone help with the below problem Please?



Remove avast4workstation from K14.04 open source
(I sent this to Avast support but no response)

I have been trying to install "avast 3.0.3-1 5.2mb" thru Muon Package Manager
in my O/S Kubuntu 14.04, but unable as fails to download , but after checking
my system I noticed that I still Have avast4workstaion still installed
from when I tried to install back in 2018? I issued a removal thru the Muon
of the avast4workstation but fails to remve as it says a file called
"libnss3-nssdb" is missing, so it won't remove the avast4workstatiion, so I
can install avast 3.0.3-1, so what should I do?
