The Threat

Email which:

• Contains an unexpected file to open or download.
• Contains a link/URL to a company for you to correct or enter personal information.
• Contains information suggesting you delete a file from a known virus.
• Contains a link/URL to purchase discount pharmaceuticals or name brand software.

These are all designed to trick you into infecting your computer, disclosing personal information, confirming a valid email address for future spam, or deleting an important system file to render your machine inoperable.
