Threat Details:
Categories:
trojan
Description:
Win32.Agent.mds copies several malicious files to the system directory of the operating system and installs a service to get launched on every Windows startup. Additionally it tries to connect to a Chinese website in order to get new commands to harm the computer.
Removal Instructions:
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
The file at "<$PROFILE>\<$REGMATCH1>.exe".
The file at "<$SYSDIR>\drivers\securentm.sys".
The file at "<$SYSDIR>\msupdt.exe".
Make sure you set your file manager to display hidden and system files. If Win32.Agent.mds uses rootkit technologies, use our RootAlyzer (http://forums.spybot.info/downloads.php?id=8) or our Total Commander anti-rootkit plugins (http://forums.spybot.info/downloads.php?id=3).
You will have to use a global search for files without a name specified. Be extra careful, because just the name might not be enough to identify files!
Important: There are more files that cannot be safely described in simple words. Please use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd) to remove them.
