Got my new computer :) Can I still copy lepou and impulses from comp to comp?

[metallicaguy1]

I got an i5 today and am happy with it so far. Just wondering if I can copy impulses and lepou plugins/cab enhancers from comp to comp via external hdd?

I thought about just redownloading them since they're free (they still are, aren't they?) but am afraid of viruses. I'm not sure which sites are legit now, since when I did download them before... that was quite a while ago.
