Web Attack: Facebook Fake Survey 3

Hello,  below is my alert details,

I am facing this alert while browsing my website at http://consumerwebreports.org/ecig/?&t202id=&t202kw=&match=&c3=

 

My test cases : 

I check full code but nothing found, for other anti-virus, there is no error, 

When i enable adblock extension then its doesnot show me error,

There is an variable in script  like 

 

now = new Date();
threeweeksfromnow = new Date(now.getTime() + (1 * 1 * 60 * 60 * 1000));

 

When i replace threeweeksfromnow  by twoweeksfromnow then it work fine, so i can guess this will problem with threeweeksfromnow keywords but i am very instrested to know why this alert comes with threeweeksfromnow or is there any other reson that give this page,

 

 

Please help me to find out the problem,
