This is an abused website by many virus-makers and trick people to click the link and it redirects you to a virus website.
Why would anyone create a website to shorten names of other websites???

Of course it safe!!!
It's a e-mail by the way.

It is a really fast english dictionary... fast like a ninja.
Easy and good to use when you can't understand words.

Who would ever trust a website with a name of a virus???

There is a high risk of malwares in the downloads.
