virus detection in evolution

[Charles Malespin]

Hi all, I use evolution to get my gmail mail and sort them out with one
folder for this mailing list, and one for personal mail. Is there
something I can use to scan emails for viruses and things like that?  I
am running a default set up of hoary so is there something already
enabled to help this out?  I dont want anything super crazy or
complicated, just something I can scan individual emails with or just
kinda filter all the emails I get.  Nothing too difficult please!
Thanks, 
Charles
