它修改 Internet Explorer 區(qū)域设置。
下载例程
它访问下列网站下载文(wén)件:
- http://{BLOCKED}ebabanahujtr.org/53648768.zip
它使用(yòng)下列文(wén)件名(míng)保存下载的文(wén)件:
- "%Application Data%\Microsoft\Crypto\RSA\RSA{Volume ID}.dll"
- "%Application Data%\defragsvc.dll"
(注意: %Application Data% 是当前用(yòng)户的 Application Data 文(wén)件夹,通常位于 C:\Windows\Profiles\{user name}\Application Data (Windows 98 和 ME)、C:\WINNT\Profiles\{user name}\Application Data (Windows NT) 和 C:\Documents and Settings\{user name}\Local Settings\Application Data (Windows 2000、XP 和 Server 2003)。)
亚信安(ān)全将下载的文(wén)件检测為(wèi):
- TROJ_ROVNIX.YPOD
它然后执行已下载的文(wén)件。结果,已下载文(wén)件的恶意例程将呈现在受感染的系统中(zhōng)。

解决方案
Step 1
对于Windows ME和XP用(yòng)户,在扫描前,请确认已禁用(yòng)系统还原功能(néng),才可(kě)全面扫描计算机。
Step 3
重启进入安(ān)全模式
Step 4
禁用(yòng)该恶意软件服務(wù)
