Over Five Million unique malware types were created in 2007

Lightning During the past two years, we have gradually moved from computer virus attacks to more uniquely packaged trojan horse attacks that are being massively spammed.  For example, the Storm worm is highly polymorphic and can change it's signature pattern (as measured by MD5 hash totals) on an hourly basis.  AV vendors are struggling to handle these constantly changing conditions, as a unique malware agent can be created for each spam run.
