What is phishing?: In the field of computer security, phishing is the criminally fraudulent process of attempting to acquire sensitive information such as usernames, passwords and credit card details by masquerading as a trustworthy entity in an electronic communication.

In the second link look for:
Spam (electronic), unsolicited or undesired electronic messages
E-mail spam, unsolicited or undesired bulk email messages

On the other hand and speaking about security do not ever rely on somebody else's security system. Install your own antivirus/security software and do not ever reply to any message asking you to disclose your personal and "critical" information. Just be safe.

Hope the readings can give you some sort of clarification and guidance.

Regards!!
