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.
Characteristics
This software is not a virus or a Trojan. It is detected as a "potentially unwanted program" (PUP). PUPs are any piece of software that a reasonably security- or privacy-minded computer user may want to be informed of and, in some cases, remove. PUPs are often made by a legitimate corporate entity for some beneficial purpose, but they alter the security state of the computer on which they are installed, or the privacy posture of the user of the system, such that most users will want to be aware of them.
Avert® Labs has observed the following system activities:
| Activity | Risk Level |
Enumerates open windows
| Medium |
Creates an Internet Explorer tool bar
| Informational |
Creates registry keys and data values to persist on OS reboot
| Informational |
Performs a shell execute of downloaded or existing files
| Informational |
| Registers DLLs | Informational |
System Changes
These are general defaults for typical path variables. (Although they may differ, these examples are common.):

%SystemDir% = \WINDOWS\SYSTEM (Windows 98/ME), \WINDOWS\SYSTEM32 (Windows XP/Vista), \WINNT\SYSTEM32 (Windows NT/2000)
%ProgramFiles% = \Program Files

Removal
All Users:
Please use the following instructions for all supported versions of Windows to remove threats and other potential risks:
1.Disable System Restore (Windows ME/XP only).
2.Update to current engine and DAT files for detection and removal.
3.Run a complete system scan.
Modifications made to the system Registry and/or INI files for the purposes of hooking system startup, will be successfully removed if cleaning with the recommended engine and DAT combination (or higher).
General repair may be unsuccessful in some instances. If this occurs, please submit a sample for further evaluation.
