Hi guys,

Today was attacked by the ever so famous XP Security 2012 virus. In the course of removing the virus, I lost all internet connection.

I have tried unplugging the modem plus router...disabled and enabled the network...and still no such luck.

Any help would be greatly appreciated.

For now we have one registry key missing.

Following steps involve registry editing. Please create new restore point before proceeding!!!
How to:
XP - http://support.microsoft.com/kb/948247
Vista and Seven - http://www.howtogeek.com/howto/windows-vista/create-a-restore-point-for-windows-vistas-system-restore/


Download XP.zip file from here: http://www.smartestcomputing.us.com/files/download/9-registry-network-keys/
Unzip the file.
You'll find six files inside.
Right click on afd.reg file, click "Merge".
Allow registry merge.
Restart computer, check on internet connection and post new FSS log

Internet is now up and working. I do use WISE registry cleaner. Is there a particular registry that I need to click off so this never happens again? Is there any programs out there that can prevent that Trojan from happening again? Thanks again for your help Broni!

I do use WISE registry cleaner

Please uninstall it.
Registry cleaners/optimizers are not recommended for several reasons:

  • Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.

    The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Understanding The Registry.
  • Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.
  • Not all registry cleaners create a backup of the registry before making changes. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE making any changes to the registry.
  • Improperly removing registry entries can hamper malware disinfection and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.
  • The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".
Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great.

As for your infection see steps here: http://www.bleepingcomputer.com/virus-removal/remove-xp-security-2012
When done post Malwarebytes log.
