Threat Details:
Categories:
trojan
Description:
Win32.Bagle.upg copies itself to several directories, installs a rootkit and avoids starting of security software. Additionally it uses a lot of system resources so the computer gets very slow.
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 "drvsyskit" and pointing to "*".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
The file at "<$APPDATA>\drivers\winupgro.exe".
The file at "<$SYSDIR>\srosa2.sys".
The file at "<$SYSDIR>\wfsintwq.sys".
Make sure you set your file manager to display hidden and system files. If Win32.Bagle.upg 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!
Registry:
You can use regedit.exe (included in Windows) to locate and delete these registry entries.
Delete the registry key "bisoft" at "HKEY_CURRENT_USER\Software\".
Delete the registry key "srosa" at "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\".
Delete the registry key "srosa" at "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\".
Delete the registry key "srosa" at "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Services\".
Delete the registry key "WS4001" at "HKEY_CURRENT_USER\Software\".
