haven't heard of this one (yet) but any time you get a link in an email don't click on it. Email the person back and ask them if they sent it. Many times I get emails from friends and I can tell right away their email has been hijacked.
Do you have any website protection to warn you of potentially bad sites? I use WOT on all my browsers
(nice little video to show you how it works- click on the bottom right broken square to open in full screen) and for web based emails it lets me know if it is green, yellow or red. (good, be careful, stay out).
I get/see a lot of red ones in facebook and my GMail. If there is anything suspect I simply delete links or hover my cursor over the link and go down the list to 'check wot's scorecard
'. Or you can copy and paste any link into the search on the last page I linked to and have WOT check it.
After all that is said and done.... the safest thing to do is never open links within emails unless the sender says they have added one. For all others in web sites I do have a level of trust with WOT or McAfee's Site Adviser
Both add on's are free and I'll take all the protection I can get LOL.
