I am not talking about ports. I am talking about attached files that may or may not be infected. >> Correct, but impractical. AGA> It's very practical. I've been doing it for years.

There is no 100% protection, if you need to open those files. But some protection is better than none. This is where the quality of AV software (freeware or pay-for-ware) comes into the equation. >> Please educate me how to tell an infected file from a clean one >> without a virus scanner.

To the extent that I scan the attachments if I really need to see them. Which does happen. What's a "trusted source" anyway? I get business proposals from people who attach company profiles. I don't know these people. Should I reject all proposals from people who I don't know yet? Unlikely. Be reasonable. -- Cheers, Thomas. What to not say to the nice policeman: I was trying to keep up with traffic. Yes, I know there is no other car around--that's how far ahead of me they are.
