what follows is copied straight from the web. I could have made a more careful job in providing these information but you are in a hurry. Hope it helps:

Troj/Zlob-JW is a Trojan for the Windows platform.

When Troj/Zlob-JW is installed the following files are created:


The file hpD1A.tmp is registered as a COM object and Browser Helper Object (BHO) for Microsoft Internet Explorer, creating registry entries under:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\(f79fd28e-36ee-4989-aa61-9dd8e30a82fa)

Troj/Zlob-JW changes Start Page and search settings for Microsoft Internet Explorer by modifying values under:

HKCU\Software\Microsoft\Internet Explorer\Search\
HKCU\Software\Microsoft\Internet Explorer\Main\Start Page

Registry entries are set as follows:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objecta\(f79fd28e-36ee-4989-aa61-9dd8e30a82fa)\

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objecta\(f79fd28e-36ee-4989-aa61-9dd8e30a82fa)\(default)


1. Disable System Restore (Windows Me/XP).
2. Update the virus definitions.
3. Run a full system scan and delete all the files detected.
4. Delete any values added to the registry.

Navigate to the subkey and delete value:

Value: "nvctrl.exe" = "nvctrl.exe"

Navigate to and delete the following subkeys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objecta

5. Exit the Registry Editor.

Hope I helped ;)
Good luck
