1. Updating the virus definitions
If your computer shows symptoms of this program, update your virus definitions.

There are two ways to obtain the most recent virus definitions:
  • Running LiveUpdate, which is the easiest way to obtain virus definitions: These virus definitions are posted to the LiveUpdate servers once each week (usually on Wednesdays), unless there is a major virus outbreak. To determine whether definitions for this threat are available by LiveUpdate, refer to the Virus Definitions (LiveUpdate).
  • Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted on U.S. business days (Monday through Friday). You should download the definitions from the Symantec Security Response Web site and manually install them. To determine whether definitions for this threat are available by the Intelligent Updater, refer to the Virus Definitions (Intelligent Updater).

    The Intelligent Updater virus definitions are available: Read "How to update virus definition files using the Intelligent Updater" for detailed instructions.

2. Scanning for and recording the filenames
This procedure runs a full system scan and deletes all the files detected as Hacktool.KeyLoggPro.
  1. Start your Symantec antivirus software and make sure that it is configured to scan all the files:
    • For Norton AntiVirus Consumer products, refer to "How to configure Norton AntiVirus to scan all files."
    • For Symantec AntiVirus Enterprise products, refer to "How to verify a Symantec AntiVirus Corporate product is set to scan all files."
  2. Run a full system scan.
  3. If the scan detects any files as Hacktool.KeyLoggPro, write down the filenames.

3. Deleting the value from the registry
CAUTION : Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified keys only. Read the document, "How to make a backup of the Windows registry ," for instructions.
  1. Click Start, and then click Run. (The Run dialog box appears.)
