Denial of service
Malicious software that copies itself into other executable programs
Tricks users into running the infected software
A set of computer instructions that lies dormant until triggered by a specific event

Ping of death
Identification and authentication
Only e-mail programs need to be protected.
Only hard drives can be protected.
Only after a virus is known can an anti-virus update be created for it.
Only computers with a direct Internet connection need it.
Anti-spam software can be loaded on either the end-user PC or the ISP server, but not both.
When anti-spam software is loaded, legitimate e-mail may be classified as spam by mistake.
Installing anti-spam software should be a low priority on the network.
Even with anti-spam software installed, users should be careful when opening e-mail attachments.
Virus warning e-mails that are not identified as spam via anti-spam software should be forwarded to other users immediately.
