Installed debian package by clicking on the downloaded file on my desktop.
Seemed to install... AVAST showed on the mint menu.
But when clicked, I get a message stating that file cannot be found.
... so to the terminal and do an apt-get removal.
All seemed gone now and not in menu either.
Now if I try to go to Synaptic Package Manager, I get this error:

If I try to re-install, I now get this error:

Downloaded the same package again and I do have permissions to this file too

apt-get autoclean did not help either.
Synaptic Package Manager is unaccessable - even tho I did not use it at all to install AVAST.
BleachBit shows:
E: The package avast4workstation needs to be reinstalled, but I can't find an archive for it.
The 3 files left for Avast are in the usr/bin directory:
Avast - broken/Root permissions - target../lib/avast4workstation/bin/wrapper-script.
AvastGui - broken/Root permissions - target../lib/avast4workstation/bin/wrapper-script.
Avast Update - Broken - 0 data/UnKnown
what else can I try to resolve this ?
