    Trojan.Gen.2 is a generic detection for many individual but varied Trojans for which specific definitions have not been created. A generic detection is used because it protects against many Trojans that share similar characteristics.

    Trojan horse programs pose as legitimate programs or files that users may recognize and want to use. They rely on this trick to lure a user into inadvertently running the Trojan. Often a Trojan will mimic a well known legitimate file name or pose as a particular type of file, like a .jpg or .doc file to trick a user.

    Distribution of Trojans on to compromised computers occurs in a variety of ways. From email attachments and links to instant messages, drive-by downloads and being dropped by other malicious software. Once installed on the compromised computer, the Trojan begins to perform the predetermined actions that it was designed for.

    2. Restoring settings in the registry
    Many risks make modifications to the registry, which could impact the functionality or performance of the compromised computer. While many of these modifications can be restored through various Windows components, it may be necessary to edit the registry. See in the Technical Details of this writeup for information about which registry keys were created or modified. Delete registry subkeys and entries created by the risk and return all modified registry entries to their previous values.

    Hi,

    DWH***.tmp files are detected in the user profile temp directory

    http://www.symantec.com/docs/TECH92399

    These detections do not indicate a new outbreak of a threat.  The .tmp files are created by the Symantec Endpoint Protection (SEP) or Symantec AntiVirus (SAV) Quarantine scan. The scan is normally initiated by a virus definition update.

    There are also several known methods to work around the issue:

    • The quarantine scan on virus definition update can be disabled in the  Symantec Endpoint Protection Manager (SEPM): edit Antivirus and Antispyware policy > Windows Settings > Quarantine > General, under "When New Virus Definitions Arrive" choose "Do nothing".
    • Items in quarantine can be deleted.
    • If the indexing service is enabled it could be triggering the issue when the dwh***.tmp files are indexed.
    • Investigate other applications that are scanning the temp file for changes.

    IF not helped,

    Use Symantec endpoint Protection Support Tool with Power Eraser (eliminates deeply embedded and difficult to remove threats that traditional virus scanning doesn't always detect) following the article:

    If you manage to identify infected files and thay are not detected by SEP, please submit the files using this link:

    Hello Ashoka,

    You have provided very limited details.

    Could you please provide us the file name and path of the file located on? If possible please provide us a screenshot.

    Trojan.Gen is a generic detection for many individual but varied Trojans for which specific definitions have not been created. A generic detection is used because it protects against many Trojans that share similar characteristics.

    Understanding the file location and file name may give us some idea to assist you with the Threat.

    Secondly, is the name of the file starting from DWH***?

    If yes, you may check the links provided by Chetan above.

    I doubt this is the known issues. The issue of multiple DWH files being created and retained has been improved in SEP 11 Release Update 7 Maintenance Patch 2 (RU7 MP2) and SEP 12.1 RU1 MP1.

    Check these Articles below:

    When new virus definitions are in place and the quarantine is being scanned, a DWH file is created and detected by Auto-Protect

    http://www.symantec.com/docs/TECH102953

    DWH***.tmp files are detected in the user profile temp directory.

    Hope that helps!!

    I am agree with aobve comments if your systems are infected with dwh.tmp related virus then updgrade the Sepm version with (SEP 11 Release Update 7 Maintenance Patch 2 (RU7 MP2)). It will fixup .tmp file issue.

    What was the action taken? If cleaned, deleted, or quarantined than SEP did its job and no further action is needed.
