a while ago I installed Linux Mint 15 on my PC. The main reason to install comodo (version: 1.1.2268025.1, virus database version: 16783) on it was, not to become a virus-slingshot for others at the reception and sending of emails.
To see if it works well, I let me send a few test viruses from heise.com.
I tried for example
From the category file attachments the “executable file (exe)” or the “ZIP archive with exe file”.
[*]Or from the category Dummy viruses “Standard test virus (EICAR)”
I tried it with my email client KMail.
The result: CAVL recognized nothing! All the emails came in and I could send it unchanged! :-TD
[EDIT: I forgot to mention: I have sent the same test-emails to an other PC with Windows and avast antivirus free on it, and it detects ALL emails right before they could land in the email client (thunderbird) and does the default response (asking me what to do with it, move to virus vault, delete …)]
It would be nice if anybody might feel free, to test also some of these test-viruses with his CAVL in order to see, if the result is the same.
