TECHNICAL DETAILS

When Dialer.LiveVideo_fi runs, it does the following:

1. Copies itself to C:Program FilesComsoftDialersLiveVideo_fiLiveVideo_fi.exe.
   
   
2. Opens TCP and UDP connections to a Live Video Web site, which is sexual in nature. UPD/TCP ports are selected sequentially starting with 1020. Port numbers are incremented each time the dialer runs. Increments are usually 5 or 6, so if port 1025 is used one time, port 1031 might be used the next time.
   
   
3. Adds the registry key:
   
   HKEY_LOCAL_MACHINESoftwareComSoft
   
   
4. Adds the value:
   
   "LiveVideo_fi"="C:Program FilesComsoftdialersLiveVideo_fiLiveVideo_fi.exe"
   
   to the registry key:
   
   HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun
   
   so that the dialer loads when you start Windows.

Dialer.LiveVideo_fi has an associated uninstaller.

1. Updating the virus definitions
Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. 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. To close modem connections
This risk uses available modems to create an Internet connection, sometimes without any visible signs. In order to successfully remove this threat, ensure that all modem-based Internet connections are disconnected before proceeding. For instructions on how to do this, consult the appropriate Internet service provider, computer manufacturer, or operating system documentation.

3. Uninstalling the Dialer
