Threat Details:
Categories:
trojan
Description:
The trojan drops malicious files into several subdirectories into the "C:\Windows\System\" directory and creates an autorun entry named "firewall". Also installs software that is able to spy on your internet banking.
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 "firewall" and pointing to "C:\WINDOWS\system\ruso\firewall.exe".
Entries named "firewall" and pointing to "<$WINDIR>\system\ruso\firewall.exe".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
The file at "<$WINDIR>\system\ruso\counter.ini".
The file at "<$WINDIR>\system\ruso\firewall.exe".
The file at "<$WINDIR>\system\ruso\bcp\index.html".
The file at "<$WINDIR>\system\ruso\bcp\OperacionesEnLinea\images\new\zona_segura\tit_ingresa.gif".
The file at "<$WINDIR>\system\ruso\images\zona_segura.css".
Make sure you set your file manager to display hidden and system files. If Win32.Delf.cof 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.
Folders:
Please use Windows Explorer or another file manager of your choice to locate and delete these folders.
