Norton Safeweb Shows 1 Phishing Threat for https://www.i-parcel.com

Hello,

 for at least two days Norton Safeweb has shown 1 phishing threat for the website of the UPS company i-Parcel, however no precise details other than,

Location : http://notification.i-parcel.com/track/click/30173527/ops.i-parcel.com

On Google Chrome a warning page appears and a recommendation not to visit the site. 

I need to enter a tracking number and track a package at this website. Is there someway of determining whether it is safe to do so ?

 Thank you.
