from what I could find it is a JS command, if you have JS installed then go to settings - security and turn off Java to run in your browser this can also fix issues for older Poser versions that load JS Trackers or redirectors ....

you can also go into the hidden folder where it generates the file , make a empty dummy htm file ( Name it "search_parms[1].htm" ) and set it protected, the file can not be overwritten or removed after shutting down poser, the redirector JS file can not be generated on your machine for poser in the AppData\Local\Microsoft\Windows\INetCache\IE
