Threat Details:
Categories:
trojan
Description:
The file taskdir.exe installs taskdir~.exe into the system32 folder, and runs in background. This file connects to the internet and downloads a file called scane.exe. taskdir.dll hides all files with a "taskdir" in their name. taskdir.exe checks every 5 seconds the hidden file index.dat in the TIF (Temporary Internet Files) folder. The users surfing behaviour can be found out that way. How to clear index.dat: http://www.zdnet.de/enterprise/os/0,39023494,20000261,00.htm

Please use Windows Explorer or another file manager of your choice to locate and delete these files.

Make sure you set your file manager to display hidden and system files. If Win32.Lager.aq 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.
Delete the registry value "<$SYSDIR>\ss.exe.exe" at "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List\".
Delete the registry value "<$SYSDIR>\ss.exe.exe" at "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List\".
Delete the registry value "<$SYSDIR>\ss.exe.exe" at "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List\".
If Win32.Lager.aq uses rootkit technologies, use our RegAlyzer (http://www.safer-networking.org/index.php?page=regalyzer), RootAlyzer (http://forums.spybot.info/downloads.php?id=8) or our Total Commander anti-rootkit plugins (http://forums.spybot.info/downloads.php?id=3).
Final Words:
If neither Spybot-S&D nor self help did resolve the issue or you would prefer one on one help,
Please read these instructions (http://forums.spybot.info/showthread.php?t=288) before requesting assistance,
Then start your own thread in the Malware Removal Forum (http://forums.spybot.info/forumdisplay.php?f=22) where a volunteer analyst will advise you as soon as available.
