Additional type information.
Date that AVERT discovered this threat.
File size, in bytes, of the threat.
McAfee DAT files contain detection and repair information for threats. The Minimum DAT field specifies the lowest/oldest DAT version that is capable of detecting the first incarnation of a threat, and the release date. The highest/newest DAT version should always be used for the most complete protection and are available on the Anti-Virus Updates page.
Each description displays the minimum, fully tested, DAT version that includes regular detection for a particular threat. These fully tested DATs are released on a daily basis. If necessary, they are also released when a Medium, Medium On Watch, or High risk threat is discovered. An EXTRA.DAT will also be posted for these more prevalent threats, if necessary.
For each description listed, detection is always available. In the event that the DAT version specified is not yet available, an EXTRA.DAT file may be downloaded via the McAfee AVERT Extra.dat Request Page. Alternatively, minimally tested HOURLY BETA DAT files are available for downloading.
McAfee DAT files are constantly being updated to enhance detection capabilities. The Updated DAT field specifies the released DAT version that contains the most up to date detection.
The scan engine uses the DAT files to detect threats. The Minimum Engine field specifies the lowest/oldest engine version that is capable of detecting this threat. The highest/newest engine version should always be used for the most complete protection and are available on the Anti-Virus Updates page.

Overview
This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.
Characteristics
This detection is for the change in the host file as a result of executing the W32/Zotob.worm virus. The local hosts file is appended to contain several comments at the bottom.
Method of Infection
- The hosts file is changed via the execution of the W32/Zotob.worm virus.
