Malware Ahead!

It means that Google has received many reports that this site has been infected.

Not by any means Steamgift's fault.
But another party, (apparently Houstonpress In this case) infected this site through the means of Hacking, attachments in ads or w/e.

I don't get any reports on Steamgifts though.
So you might already be infected and Chrome is just confused, Thinking it's coming from here.

You might have a virus....I doubt anyone else has gotten that...A lot of people would of said something :( sorry mate

Did a google search, and it seems the forums had a few threads like this... I bet its the ads...

You should probably get tested.
