Assistant position on Craigslist

I just got 2 emails back from fake companies as I can't find them on line. One was asking me to open account with some Account Now prepaid card. I figured it's just not legit. I have a question, I did sent them my resume and cover letter. Should I report it or they can't really do anything with it?

The other company sent me a link to Facebook where I can find more info about the position. I did open the link but of course there was no page. Did I got some malware on my system? What should I do then?
