Web Attack: Fake Flash Update Download 2

Hey,

I've just been browsing online and Norton had picked up a high severity web attack from the IP address '104.28.14.9, 80' (which also found the attacker URL), which has been successfully blocked and Norton 360 says I don't need to do anything else.

I'm running a full system scan in the meantime, but I was wondering if there should be any other actions I should take (I know I sound really paranoid).

Thanks,
NickJL
