Summary
This program delivers advertising content to the user. It is usually annoying but harmless, unless it is combined with spyware or trackware.
Removal
Based on the settings of your F-Secure security product, it may block the file from running, move it to the quarantine where it cannot spread or cause harm, or ask you to select an action.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First, check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
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.
