Technical Details


This is the family description of the Adware:W32/WebHancer adware family, which contains multiple variants.

The WebHancer adware& uses the Microsoft Winsock 2 SPI API to insert itself into the TCP/IP stack in order to monitor all web traffic on the host. This information is then relayed to the WebHancer server(s). Monitored traffic details include visited websites, browser type and other statistics.

Installation

The software has no visible installation routine, but when executed will install itself to:

  • %programfiles%\webHancer\Programs
  • %programfiles%\wbinstall\

The program may also be installed bundled together with other software installations.

Example connection attempts:

  • https://prime.webhancer.com
  • https://secondary.webhancer.
Removal

It may be uninstalled from the Windows Add/Remove Programs interface.

Improper manual removal may corrupt the Winsock registry keys and break the TCP/IP stack. This may result in disabling Internet access.
