Additional Details

This trojan-dropper masquerades as a Homeview installer. In reality, its main purpose is to install Trojan:W32/DNSChanger.ARNF onto the system.

Execution

Upon execution, it will display the following fake screens, to mimic the legitimate installation sequence for Homeview:









Installation

While the fake installation screens are distracting user, the malware creates and executes this file:

  • %temp%\jah339312.exe

This file is detected as Trojan:W32/DNSChanger.ARNF.

If the fake Homeview installation sequence is completed, a new folder named %Program Files%\homeview is created and this file is added to it:

  • %Program Files%\homeview\Uninstall.exe

This uninstaller is capable of removing the Homeview-related registry entries and deleting itself and its folder. It is however incapable of removing Trojan:W32/DNSChanger.ARNF, or the changes that malware makes to the system.
