Some of the advertising featured on GiveawayOfTheDay.com may be triggering alerts from your anti-virus programs.
It's not the GAotD site itself, but some of the ads may contain links to suspected phishing websites where personal information may be gathered (I'm guessing that some of those sites may gather that information automatically, without your knowledge or permission, hence the alerts). My AV program just blocks the ad from appearing on the GAotD site.

Thought you might want a heads-up.
