I've just got sent a link from 2 people, im not sure, but is it a virus?

Firstly the person will say

hey

then say

its you!

Then they'll send me a link, that says something like

imperialhost.net/pictures/gallery[your email here]

When you open the link it asks you to download something, then once its downloaded, it sends to your contacts with their email address on the end of the link

Is this new/old? Is it a virus? If so is there a removal tool? - my friends needa download it :\

Thanks in advance
