What is http://googleads.g.doubleclick.net/pagead/test_domain.js ?

I was getting Kaspersky Security Alert as stated below everytime I browse website's with Google Adsense Content Advertisement in it.

"Application Google Chrome contains link to web page http://googleads.g.doubleclick.net/pagead/test_domain.js used to steal password, credit card number or other confidential data. Denied"

So, got bit worried whether this virus threat was a real threat or a false alert , so just browse the Net to find out more about googleads.g.doubleclick.net

Found out that there is nothing to worry about, as Google bought DoubleClick in 2007 they have some integration things to sort out and there is no harm.

To confirm the status, I sent an email to Kaspersky Virus Lab as stated below and the Virus analyst confirmed it was a false alarm.
