Don't even touch those links! They are trojans.... have very NASTY viruses imbedded in them which will spam your entire contact list.....Ask me how I know!
I've had a couple of friends send out emails without subject lines that have nothing but these links inside of them. They went to open the link since the email was from their friends and were then directed to fictitious websites. In the meantime, their entire mailboxes were copied and sent out spam with these links imbedded with their email addresses.
It took FOREVER for them to get an antivirus software to get the viruses debugged. One friend took over 3 months of repeat problems before it finally was resolved. This was IN SPITE OF THE FACT that all of them had active antivirus software running at the time the emails came in.
Bottom line - when in doubt, DON'T touch it.
Good luck getting your email cleaned out!
