Thank you very much for yout time

I want to try following your advice, actually I get more and more used 
to the command line ( I even start to find it faster than any X display) 
nevertheless I still envy the GUI like soft quick to install that could 
protect me while I learn while typing this note I fear for my data  I 
have lost about 600 Mo I guess

I recently  used the Anti vir command line Soft 
Un fortunately it seem 2  scan a directory and does not seem to scan 
files Also if I select / to be scanned then the reprot would say 
 directories ( or so) scanned in about 1 minute

I guess I have to read more about it for it to funcyion, in the mean 
while I am worried as I have lost so much because of that hacker ( my 
provider do not want to know about it) this is France U know...

Thank for your help once more Ed
