I was sent a profile link to this "AlphARomeo" He may seem legit, but look at the link.

http://steazommunity[FAKE WEBSITE]
The link is fake. Seriously? STEZommunity?

It is a total fake, and in the friends list, is none other than... PalmDesert, The_Cpt_FROGGY, And Renfield, this is him and his two other friends. This is a fake website, it says you are logged out and makes you log back in, this is a Hijacking website, and once you put in your password and username, you get a download link to get "steam-guard.exe"
This told me, always look at the link before you log in.
I almost fell for this, you shouldnt fall for it.

Oh and the guy who sent me the link is

[EDIT]

You also cannot find AlphARomeo if you try to find him in the friend finder that Valve made.
Another way to find out if a fake.
