Threat Details:
Categories:
malware
Description:
When started, the application deletes the "System" and "System32" directories, the "SystemCertificates" directories of the users, "\Shared Folder\System" and the "pchealth" directory. It redirects hosts of anti-spyware vendors and deletes the system.ini file. If the computer is infected with this malware, reinstallation of system components is required. A variant of Win32.Rbot.gen copies an executable file into the System directory, starts itself in autorun as "FrameWork 2.5" and tries to connect to the internet in background without giving the user a possibility to cancel that process.
Supposed Functionality:
Officially known as a Trojan with Backdoor functions.
Removal Instructions:
Autorun:
Please use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd), RunAlyzer (http://www.safer-networking.org/index.php?page=runalyzer) or msconfig.exe to remove the following autorun entries.
Entries named "Windows File Migration Wizard" and pointing to "HIMENSYST.EXE".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
The file at "<$SYSDIR>\HIMENSYST.EXE".
A file with an unknown location named "HIMENSYST.EXE".
Make sure you set your file manager to display hidden and system files. If Win32.Rbot.gen uses rootkit technologies, use our RootAlyzer (http://forums.spybot.info/downloads.php?id=8) or our Total Commander anti-rootkit plugins (http://forums.spybot.info/downloads.php?id=3).
You will have to use a global search for files without a name specified. Be extra careful, because just the name might not be enough to identify files!
Important: There are more files that cannot be safely described in simple words. Please use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd) to remove them.
Registry:
You can use regedit.exe (included in Windows) to locate and delete these registry entries.
Remove "Windows File Migration Wizard" from registry value "Windows File Migration Wizard" at "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices".
Delete the registry value "<$SYSDIR>\HIMENSYST.EXE" at "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List\".
