Behavior
The program reports false or exaggerated system security threats on the computer.







The user is then prompted to pay for a full license of the application in order to remove the threats.





Installation
When the program is executed, it creates the following files:

• %UserProfile%\Local Settings\Application Data\[THREE RANDOM LETTERS].exe
• %UserProfile%\Local Settings\Application Data\2e01oq0m46k223
• %UserProfile%\Local Settings\Temp\[RANDOM FILE NAME]
• %UserProfile%\Templates\[RANDOM FILE NAME]

Next, it creates the following registry entries:

• HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\DomainProfile\"EnableFirewall" = "0"
• HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\DomainProfile\"DoNotAllowExceptions" = "0"
• HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\DomainProfile\"DisableNotifications" = "1"
• HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\"EnableFirewall" = "0"
• HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\"DoNotAllowExceptions" = "0"
• HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\"DisableNotifications" = "1"
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\DomainProfile\"EnableFirewall" = "0"
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\DomainProfile\"DoNotAllowExceptions" = "0"
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\DomainProfile\"DisableNotifications" = "1"
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\"EnableFirewall" = "0"
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\"DoNotAllowExceptions" = "0"
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\"DisableNotifications" = "1"

It then modifies the following registry entries:

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\"AntiVirusDisableNotify" = "0"
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\"FirewallDisableNotify" = "0"
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\"UpdatesDisableNotify" = "0"
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\"AntiVirusOverride" = "0"
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\"FirewallOverride" = "0"

The program then deletes the following registry subkeys:

• HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\LEGACY_WUAUSERV
• HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\wuauserv
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_WUAUSERV
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv

2. Restoring settings in the registry
Many risks make modifications to the registry, which could impact the functionality or performance of the compromised computer. While many of these modifications can be restored through various Windows components, it may be necessary to edit the registry. See in the Technical Details of this writeup for information about which registry keys were created or modified. Delete registry subkeys and entries created by the risk and return all modified registry entries to their previous values.
