How Did I Get Eorezo Adware

The main method by which your system may have become compromised by this ad-supported software is via a Trojan horse, detected as Trojan.Milicenso which uses the Microsoft Windows Print Spooler Service Remote Code Execution Vulnerability (CVE-2010-2729). When this Trojan infects your computer, it checks if you are running Windows on a Virtual Machine and if so, it shuts itself down. If not, the malware drops the Eorezo adware and then drops a .bat file, located in the %Temp% directory.

The Milicenso Trojan also drops other files, named randomly in the following Windows directories:

%System%\{random name}.dll
%WindowsDir%\Tasks\{random name}.job

The Trojan also drps Windows registry entries in the following Windows registry entries:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\

The virus then connects to multiple third-party hosts, reported by Symantec(Symantec.com) to be the following:

From there, it drops the Eorezo adware on your computer and it may also drop other malicious files and malware on it.

Eorezo Adware – Analysis

When the Eorezo adware is dropped on your computer by the Milicenso Trojan, the ad-supported program drops multiple files on your computer system, in the following locations:
