Don't understand how to customize antivirus

Hello,

I have Microsoft Security Essentials, and am happy with it. But I don't understand how to use it in individual situations, such as downloading a program from a website. For example, there are trusted websites I download from but I would like to scan the

program beforehand, and I don't know how to do it. Nothing I read seems to explain how to do so sufficiently.

I do know, for example, that I need to right click on a flash drive to scan it with my antivirus, but I still don't get how to scan email attachements and software from the Internet.

Second question: I received a scam email from "Fedex," which asked that I click a receipt in order to pick up a package. I opened the email itself because I was expecting a Fedex package, but I never clicked on the receipt. Should I worry about having a

virus? I have run my scan and nothing appears to be infected, but that might not mean anything. I subsequently called Fedex and they confirmed it was a false email.

Thanks
