Threat Details:
Categories:
trojan
Description:
Win32.Autorun.bn copies an executable file into system directory and autorun.inf to the harddrives and starts itself in autorun (as "IEXPLORER") without giving the user a possibility to cancel that process.
Also changes file type association for Registry Editor and antivirus software in registry.
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 "<$ENV(WARBN1)>" and pointing to "<$SYSDIR>\<$ENV(WARBN1)>.exe".
Entries named "IEXPLORER" and pointing to "<$SYSDIR>\iexplorer.exe".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
The file at "<$SYSDIR>\iexplorer.exe".
The file at "<$SYSDIR>\sysurl.dll".
The file at "<$SYSDIR>\wuauc1t.exe".
Make sure you set your file manager to display hidden and system files. If Win32.Autorun.bn 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.
