Removal Instructions:
Autorun:
Please use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd), RunAlyzer (http://www.safer-networking.org/index.php?page=runalyzer) or msconfig.exe to remove the following autorun entries.
Entries named "Dexon" and pointing to "<$SYSDIR>\dat\Dexon\Agent\*.exe".
Entries named "Dexon" and pointing to "<$SYSDIR>\dat\Dexon\Agent\dummy.exe".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
The file at "<$SYSDIR>\dat\Dexon\Agent\Agent.exe".
The file at "<$SYSDIR>\dat\Dexon\Agent\Agent_Distrib.exe".
The file at "<$SYSDIR>\dat\Dexon\Agent\Agent_Setup.exe".
The file at "<$SYSDIR>\dat\Dexon\Agent\cfg.dxn".
The file at "<$SYSDIR>\dat\Dexon\Agent\dexon_browser.exe".
The file at "<$SYSDIR>\dat\Dexon\Agent\Dexon_RC.exe".
The file at "<$SYSDIR>\dat\Dexon\Agent\Dexon_SSH.exe".
The file at "<$SYSDIR>\dat\Dexon\Agent\dummy.exe".
