Landon Medrano, the leader in Kaspersky PURE antivirus center, said around 178752 computers were infected by Trojan:Win32/Adialer.FK everyday. When Trojan:Win32/Adialer.FK loads, it starts to download and install malware Program:Win32/BaiduIebar from http://download.cnet.com. At the same time, Trojan:Win32/Adialer.FK will collect private information from the affected machines and then upload these data to the remote server through electronic means.
Trojan:Win32/Adialer.FK will close and delete itself after Program:Win32/BaiduIebar installation. The most severe issue next is Program:Win32/BaiduIebar will scan your computer, display around 3536003 false system errors and ask you to pay to clean them to fix Classpnp.sys problem.
