Thank you everybody for your help.
I’ve sent the file to Kaspersky’s lab and they answered me that it is far from being a virus.
I think this file is mistakenly taken as a virus by the Norton’s AV. Since no other AV scanner did recognized it as a virus I would suggest everyone to use additional check like the on-line scanners from kaspersky and trend to be certain that something is a virus if nothing weird is happening on your computer.
Thanks again.
