What E-Mail Attachments Shouldn't I Open?

• any attachment from a complete stranger. If you haven't advertised for a secretary, and you get a resume from someone, think twice. If it's a legitimate solicitation for work, they won't mind if you email them back requesting that they copy and paste their resume into the body of their email message.
• any attachment that ends in .bat .com .exe .hlp .pif or .scr (None of these should be emailed).
• any attachment from a suspicious email address yourwebhelper@yahoo.com definitely would fall into that category! 
• an unsolicited email from your bank (especially if you haven't provided them with your email information). Legitimate emails from banks instruct you to log into your account to do something. They don't send email attachments.
• any attachment from a friend or coworker who is know to have virus problems.  Especially if they are sending it through a mail system that doesn't scan for viruses. 

Hope this helps you stay virus free!
