f-prot virusscanner for email ?

Hello, until now I don't scan my Linux only system for viruses, but since I get more and more MS Word Documents which I open with OpenOffice I fear that I get macro viruses, since OO convertes quite well. Do I need to be afraid of these viruses? With Windows I used in the past f-prot (www.fprot.org) to scan my system, this is now also availabel for linux. How is the experience with this program? I thought of installing the f-prot start command in KMail so that the Mail directory will be scanned when a Mail is received. I this a good idea or is thee a better solution for a dialin connecton? Sorry when these questions are ot so prefessisonal - I still work on the bases of linux. Thanks a lot Michael
