I run Incredimail Premium build 1488 with AVG Professional v7 and although a silver surfer set it up and it worked first time. ( the free version I could not get working!) All incoming mail is checked, text messages have a little note at the foot with the virus database number used for the check and HTML messages have a small attachment which tells you the same thing. AVG site has a dummy virus you can download for testing purposes. The AVG Pro is an excellent item. I beta test for Incredimail and recently whilst testing had over 2000 emails in 24 hours passing through this setup without mishap. Ignore all the comments made about spyware and adaware with Incredimail! The only problem with Incredimail is that it is very hungry with resources.
