all pop email clients ( eudora, outlook or netscape email apps ) have the option, you can say do not download any attachments. with av running checking the body of the message and the attachment only when you choose to download by clicking on it, you have no email virus getting through at all. M$ seems to be the target of choice for viruses, because they have so many holes in the system security. mac isn't as vulnerable, nor is linux, extremely rare for a virus to be coded for them. btw, hmmm....Mcafee and Symantec both have nothing on KLEV they list very old KIEV virus. infects .com files, do damage. copied EA's virus name, had to work to even get the kiev virus data. nothing for klev or klez ( L not I ) no virus name as such. just so you know. when the av companies haven't got that virus listed either it isn't a virus or it is brand spanking new.
