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.

Characteristics
This detection is of application type for "potentially unwanted applications". It is not a virus nor a trojan.
The files mentioned below were found on a system in Japan that had been compromised using other files. Although the files as such may not be malicious by design, their abuse in finding remote vulnerable systems using portscanning files make such files arguable hence the detection with application.
The following package files were encountered:
- pscan2
, ELF binary file, 21407 bytes
- ss
, ELF binary file, 453972 bytes
- sshf
, ELF binary file, 842424 bytes
- assh
, asci shell file , 605 bytes
- auto
, asci shell file , 206 bytes
- go
, asci shell file , 85 bytes
Log files indicated that the compromise was initiated from Italy and/or Romania.
Users who would like to check for the presence of this program on their system should run the command line scanner with the /PROGRAM switch. Please note that VirusScan 7 and higher has an option, which enables users to detect this kind of program automatically.
