Advanced Threat Protection Glossary of Terms

Malware, short for malicious software, is an umbrella term used to refer to a variety of forms of hostile or intrusive computer software. 

Phishing is the attempt to obtain sensitive information (passwords, credit card numbers, etc.) by disguising electronic communications (typically email) to look like the request for information is coming from a trustworthy source, when it is not.

Ransomware is malicious software that blocks access to data until an actual "ransom" is paid.

Zero-day refers to a previously unknown vulnerability in software. This would be the first time an exploit of a particular vulnerability was seen. The anti-virus vendors haven't yet updated their virus definitions to protect against this as the vulnerability wasn't yet known.
