Strange URLs generated by Google / Token problem ?

[misty]

Hi,

In Google Webmaster Tools, and in Prestashop BO Stats, I have a lot of 404 errors, generated
I think by Googlebot.

The URLs are of this form :
http://www.mydomain.com/5jsSuXb2Qk=yO9Uoxm/vC4=IFg0Bim3ytc=mrNEy8QtmuI=

I suspect it is related to this piece of code on the pages :

   var time_start;
   $(window).load(
       function() {
           time_start = new Date();
       }
   );
   $(window).unload(
       function() {
           var time_end = new Date();
           var pagetime = new Object;
           pagetime.type = "pagetime";
           pagetime.token = "EeFNo7r8oHQ=e2o3vGA6eeo=o/fQTh2s3Ho=iLU122TAc5A=";
           pagetime.time = time_end-time_start;
           $.post("/statistics.php", pagetime);
       }
   );

I think I'm not the only one with this problem because this piece of code is also in some known websites using Prestashop.

I hope someone has an idea why I'm flooded with these 404 errors and how to solve that, thanks in advance
