A flash can't give you a virus. Flash does not work that way. If someone wanted to fuck your computer up with flash, they'd crash your machine by auto-spawning shit.
Now, a flash could direct you to a website that has a virus on it, but unless you're using the most god-awful browser ever, you'd still have to agree to download it. And anyone who downloads unknown .exe's is a moron and deserves what they get.
Use good passwords and you won't have problems.
