Threat Details:
Categories:

Description:
Win32.Agent.hc copies several malicious files into the System32 and Windows directory of the operating system and gets launched by some autorun entries. When the computer is infected with Win32.Agent.hc a spambot will get active and use the computer for sending unwanted spam mails.
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 "[system]" and pointing to "<$SYSDIR>\drivers\services.exe".
Entries named "winlogon" and pointing to "<$PROFILE>\svchost.exe".
Entries named "Online-Dienste" and pointing to "<$WINDIR>\*.exe".
Entries named "Outlook Express" and pointing to "<$WINDIR>\*.exe".
Installed Software List:
You can try to uninstall products with the names listed below; for items identified by other properties or to avoid malware getting active again on uninstallation, use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd) or RunAlyzer (http://www.safer-networking.org/index.php?page=runalyzer) to locate and get rid of these entries.
Products that have a key or property named "{474FE679-B667-42ae-99AA-ADC21CCBBE14}".
Products that have a key or property named "{625B529F-9E03-4475-9F3D-33F9B7B410F2}".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
The file at "<$PROGRAMFILES>\Microsoft Common\svchost.exe".
The file at "<$PROFILE>\svchost.exe".
The file at "<$LOCALSETTINGS>\Temp\lsas".
The file at "<$SYSDIR>\trash43EE51".
The file at "<$SYSDIR>\avifil3.dll".
The file at "<$WINDIR>\ZRRADBBI.exe".
Make sure you set your file manager to display hidden and system files. If Win32.Agent.hc 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.
