Technical Details

UrlSpy is an adware program that replaces the native Microsoft Internet Explorer searchbar with its own custom search function. Searching in UrlSpy's custom search redirects users to sites designated by the adware program; these sites may contain advertisements.

Installation

During installation, UrlSpy drops these files:

  • %SysDrive%\Program Files\Common Files\[Random].exe
  • %System%\[Random].exe
  • %System%\[Random].exe
  • %System%\[Random].exe
  • %System%\pinstaller.exe
  • %System%\Searchx.htm

Registry

During installation, the program creates the following keys:

  • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run = %System%\[Random].exe

The following key is modified to set Internet Explorer to use the adware's custom search function:
