Filtering viruses from website on forwarding email

Hi all
I was wondering if someone could advise, I have a website I am maintaining on a shoe string, (an Australian postage stamp website) I am giving away information some of the biggest stamp catalogue producers charge a heap of money for, and so it seems I have become a target, I am receiving about three emails a week (and have been for some time) via the website email notification address, currently they are sending me the MyDoom M strain, originating from a number of different addresses and countries, is there some way or a program that I can use to stop this stuff being sent in the first place or one that I can filter it before it gets to my PC, Avast has stopped them before they do anything and removed the viruses to the chest, but that is after the emails are on my system and I am concerned they will break through with something new or a variant :'(.

Usually most ISPs scan mails for viruses, if your ISP doesn’t do that, you could change to another. (Maybe your ISP already has this option and it needs to be activated…!!?)
Nevertheless if you show your mail address openly on the net, there’s no way to prevent others sending you mails (good or bad). There are different ways to filter them or scan them either on the server or with the client, as avast does.

as Asyn say " if your ISP doesn’t do that, you could change to another. "
Gmail have very good spam and virus filter. All mails are scanned with two virus programs from McAfee and Authentium

Hi,

We recommended you to protect yourself with gateway firewall included with URL Filter and AV gateway to blocked unwanted malicious program when they trying to run inside of your machine.

Or you may using AntiSpam feature to block with blacklist or smart engine to learn the contains of email sender.

cheers,
