DAZ, thank you for the link to free anti virus.
I think Antivirus should be FREE. I think the best solution again email virus is to install the Anti Virus on the mail server itself .. where all the email gathered before downloaded by users to their computer. So the Anti Virus software should target the company server and ISP.
But of course for home computer .. second protection will be good. for virus tranfered through diskette, cdrom or messenger from someone like ..
Queenbee for example.
They'll find way.
