I have tried again and now it works.
What have I changed ?
Instead of sending file “eicar.com” I have sent “eicar_com.zip”.
This means that my ISP eliminates the messages with “eicar.com” and no those with same compressed file. Because? ??? ???
Tonight I will try with other PC (win XP) and I make you know.
PS. Now I send a presumed virus to Avast team for examination.
Regard, to the next one. :slight_smile:
