Spam
Spam is not malicious software in its pure sence. Spam is unsolicited information, and may perhaps be called "nuisanceware". The most common channel for SPAM is email, although any communication channel may be used (web, Instant messaging etc.). It is estimated that email-based SPAM constitutes far more than 50% of all email traffic through the Internet.
The spammers use different techniques to attempt to avoid the spam to be detected by antispam software, e.g. using images as all or parts of the text (image spam).
