Phishing e-mails are a common way for hackers to get your personal information or break into your computer.
The e-mails can be in the form of messages pretending to be from companies like UPS or FedEx with links to package tracking information.
Experts say you should not click the links until you have confirmed that they are not malicious.
"Basically what the scammer wants you to do is open it up and put a malware or Trojan virus on your computer which just sits there and wait for you to do your financial records or apply for credit online or put your social security for something else and it steals that information as well," said Steve Bernas, Better Business Bureau.
Experts advise installing virus protection software on your computer and updating it regularly.
