More details about W32.Voterai

W32.Voterai can spread through removable media drives and network shares. It shows an image concerning a presidential candidate particularly Raila Odinga. It affects windows platform. Once this worm is executed, it copies itself to the \defaults.pif, \Installer\winlogon.exe, \Debug\explorer.exe, \dllcache\userinit.exe, and \dllcache\lsass.exe. The worm creates the image file that is displayed at regular interval. It further creates .htm, .pr and .inf file in the system folder as well as in windows folder.

This is to avoid being detected as a threat. The files added by the W32.Voterai program may be invisible on the affected computer. This is because the Trojan application has rootkit functionality. This function hides the files added by the Trojan software on the system. The W32.Voterai program is difficult to detect and remove from the computer because of this.
