Waledac worm targeting July 4 spam offensive | Security - CNET News
Security firms are warning about a worm that is spreading by fooling people into clicking on links that have to do with the 4th of July. The CNET article above has some details.
Remember that it is never a good idea to open any unexpected links or attachments that are sent to you in email, even if they appear to be from a source you know and trust. It is always safest to delete any unexpected links or attachments, if they are legitimate you can always call the sender and ask them to send them again!
Stay safe this weekend!
