Unusual modem activity, presence of aforementioned files and registry keys, and higher rates than expected in phone bills.

Trojans do not self-replicate. They are spread manually, often under the premise that the executable is something beneficial. Distribution channels include IRC, peer-to-peer networks, newsgroup postings, adult-oriented websites, etc.

All Users:
Use current engine and DAT files for detection and removal.

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).

But in some particular cases, the following steps need to be taken.

Please go to the Microsoft Recovery Console and restore a clean MBR.

On Windows XP:

• Insert the Windows XP CD into the CD-ROM drive and restart the computer.
• When the "Welcome to Setup" screen appears, press R to start the Recovery Console.
• Select the Windows installation that is compromised and provide the administrator password.
• Issue 'fixmbr' command to restore the Master Boot Record
• Follow onscreen instructions.
• Reset and remove the CD from CD-ROM drive.

On Windows Vista and 7:

• Insert the Windows CD into the CD-ROM drive and restart the computer.
• Click on "Repair Your Computer".
• When the System Recovery Options dialog comes up, choose the Command Prompt.
• Issue 'bootrec /fixmbr' command to restore the Master Boot Record.
• Follow onscreen instructions.
• Reset and remove the CD from CD-ROM drive.
