Distribution |
|
Distribution: |
Installed by ActiveX
drive-by-download by porn-related pages from nocreditcard.net
and sex-explorer.com,
which may be opened or redirected to by pop-up advertising.
May be installed automatically, without prompting, on Internet Explorer versions earlier than IE6 Service Pack 1, thanks to a security hole. The installer pages exploit this to run an EXE which adds 'Electronic Group' to the list of trusted publishers whose software IE will install automatically without asking. Electronic Group distributes other dialers as well. |
Prevalence: |

Clot Factor: |
The "Clot Factor" is a measure of how much a pest "gums up" a machine by adding registry entries, files, and directories. As more objects are placed in a machine, manual removal becomes more difficult and more error-prone. |

Security Issues: |
IEAccess adds its
manufactures to Windows's Trusted Publishers list. This
means any web page can ensure any software signed by Electronic
Group gets installed automatically when you visit it.
It is also suspected that it may be possible to use the IEAccess ActiveX control on any web page to cause arbitrary unsigned code to be executed. |
Stability Issues: |
None known. |
Detection and Removal |
|
Automatic Removal: |
|
Manual Removal: |
From 'Downloaded Program Files' in the Windows folder, right-click the 'IEDial class' entry and remove it. This does not actually get rid of the software, so open a DOS command prompt window (from Start->Programs->Accessories) and enter the following command, for Windows 95/98/Me: "%WinDir%\System\regsvr32.exe" /u "%WinDir%\System\IEAccess2.dll"
regsvr32 /u "%WinDir%\System32\IEAccess2.dll"
Finally, remove Electronic Group from your Trusted Publishers list. To do this, open the registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\WinTrust\Trust Providers\Software Publishing\Trust Database\0 and delete the entry with the value 'ELECTRONIC GROUP'. (It's probably a good idea to keep this key completely empty.) You can also go to HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates\TrustedPublisher\Certificates and delete Electronic Group's key. It should begin '08F573...'. IEAccess may have downloaded one or more unwanted diallers. Sometimes these may appear in an 'eGroup' folder in the Windows folder, as well as entries the more usual Program Files folder. Check and delete any diallers you find. |
| Remove AutoRun Reference: Go To the key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. If you find the value HKEY_CURRENT_USER\software\microsoft\windows\currentversion\run\livesrv, delete it and reboot the machine immediately. If you find the value HKEY_USERS\s-1-5-21-1085031214-484061587-839522115-500\software\microsoft\windows\currentversion\run\livesrv, delete it and reboot the machine immediately. | |
| Unregister DLLs: Unregister these DLLs with Regsvr32, then reboot: | |
| Clean Registry: Remove these registry items (if present) with RegEdit: | |
| Remove Files: Remove these files (if present) with Windows Explorer: | |
