unable to get antivirus or mount usb stick

[pingball57]

Thanks firenice.
I tried again with same result then tried your sudo apt-get install --fix-missing which i think has worked:

jpa@jpa-SATELLITE-C850D-11Q:~$ sudo apt-get install --fix-missing

jpa@jpa-SATELLITE-C850D-11Q:~$ sudo freshclam
sudo: freshclam: command not found

but I'm still getting sudo: freshclam: command not found. I used sudo apt-get upate which produced a lot of text ending;

so i tried to run clam as per tutorial

jpa@jpa-SATELLITE-C850D-11Q:~$ sudo clamscan -r -i / | grep FOUND >> /home/jpa/virus-scan-report.txt
sudo: clamscan: command not found

& got sudo: clamscan: command not found. I did all this without anyother widow open (i had a web browser window open originally to follow the instructions & copy the commands from). I take it I did the above right?

On the plus side - on trying a usb stick this evening everything worked as normal. perhaps I'd upset things with trying to get Clam.
