Url Malware on Outlook.com Sign Up Page

Viruses and worms

Sorry I posted in the wrong section earlier.

Everytime I press the signup link on the outlook.com signup page avast pops up about blocking a url malware form s2.sycmb. Is it a false positive…or outlook.com is infected?

Here is the link to the sign up button https://signup.live.com/?wa=wsignin1.0&ct=1422167777&rver=6.1.6206.0&sa=1&ntprob=-1&wp=MBI_SSL_SHARED&wreply=https:%2F%2Fmail.live.com%2F%3Fowa%3D1%26owasuffix%3Dowa%252f&id=64855&snsc=1&cbcxt=mail&bk=1422167779&uiflavor=web&uaid=844623c06f2a4038a33951e9c4bedb23&mkt=EN-US&lc=1033

My pc is clean, I ran a full boot scan

might be a false positive, it blocked the same URL for me when I tried to visit twitter earlier

It seems ok right now, can you please confirm it?
