Sality is a virus that has backdoor capabilities and executes keylogger and may infect executable files by putting its code to host files. Once it is installed, Sality virus will infect local executable files and delete all files that are associated with anti-virus and anti-spyware applications, as well as firewalls. After this, Sality runs a keylogging module that gathers all system and network information, records passwords and login names, steals all sensitive information and sends all this collected data to a predefined email address.
In addition, Sality opens a backdoor that allows the remote attacker to get the full control over the infected computer and this places any financial or banking information stored on your computer in severe jeopardy and represents a serious security risk.
Also known as: W32/Sality (McAfee), Virus.Win32.Sality.aa (Kaspersky), W32.Sality.AE (Symantec), Virus:Win32/Sality.AM (MS OneCare), PE_SALITY.EM (Trend)
W32/Sality is a parasitic virus that infects Win32 PE executable files. It is a polymorphic virus that attempts to spread by file infection. It looks for Win32 PE executable files with .EXE or .SCR file extensions, and infects any such files found on the system by appending the virus body to the host file.
The virus also attempts to propagate by copying itself with a random filename to network drives, including all removable disk drives. Sality.AA also creates an "autorun.inf" file in these drives so that the virus executes when it is accessed.
Upon execution, it drops the following files into the Windows system directory:

- %Windir%\System32\Hdaudprop.dll
- %Windir%\System32\Hdaudpropres.dll
- %Windir%\System32\Hdaudpropshortcut.exe
- %Windir%\System32\drivers\Hdaudbus.sys
- %Windir%\System32\drivers\Hdaudio.sys
- %Windir%\System32\drivers\portcls.sys
Creates the following registry keys:
- HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\WMI_MFC_TPSHOCKER_80
- HKEY_LOCAL_MACHINE\System\ControlSet001\Enum\Root\IPFILTERDRIVER
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\EnableLUA
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\GlobalUserOffline
and it downloads further malware from the following domains:
- bpowqbvcfds677.info
- aapowqbvcfds677.info
- abpowqbvcfds677.info
- d98dc9.bpowqbvcfds677.info

- d9aab7.bcash-ddt.net
- pzrk.ru
- dbcabh-ddt.net
- bddr-cash.net
- ebddrbcash.net
It also modifies the following registry entries:
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Setting\"GlobalUserOffline" = "0"
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\"EnableLUA" = "0"
and this virus also deletes entries in the following registry subkeys:
- HKEY_CURRENT_USER\System\CurrentControlSet\Control\SafeBoot
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Ext\Stats

- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects
- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects
Sality.AA bypasses the system firewall by executing the command:
netsh firewall set opmode disable
It may also disable settings related to system security. It does this by adding the following registry entries:
- HKLM\SOFTWARE\Microsoft\Security Center\AntiVirusOverride = dword:00000001
- HKLM\SOFTWARE\Microsoft\Security Center\AntiVirusDisableNotify = dword:00000001
- HKLM\SOFTWARE\Microsoft\Security Center\FirewallDisableNotify = dword:00000001
- HKLM\SOFTWARE\Microsoft\Security Center\FirewallOverride = dword:00000001
- HKLM\SOFTWARE\Microsoft\Security Center\UpdatesDisableNotify = dword:00000001
- HKLM\SOFTWARE\Microsoft\Security Center\UacDisableNotify = dword:00000001
- HKLM\SOFTWARE\Microsoft\Security Center\Svc\AntiVirusOverride = dword:00000001
- HKLM\SOFTWARE\Microsoft\Security Center\Svc\AntiVirusDisableNotify = dword:00000001
- HKLM\SOFTWARE\Microsoft\Security Center\Svc\FirewallDisableNotify = dword:00000001
- HKLM\SOFTWARE\Microsoft\Security Center\Svc\FirewallOverride = dword:00000001
- HKLM\SOFTWARE\Microsoft\Security Center\Svc\UpdatesDisableNotify = dword:00000001
- HKLM\SOFTWARE\Microsoft\Security Center\Svc\UacDisableNotify = dword:00000001
The virus sets the following registry entry so that hidden folders and files are not displayed in Windows Explorer view:
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Hidden = 2
It also disables Registry Editor and Task Manager by adding these registry entries:
HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\system\DisableTaskMgr = dword:00000001
HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\system\DisableRegistryTools = dword:00000001
Sality.AA terminates all anti virus routine services running on the system, and prevent access to Websites that contain its names, like sality_remove, viruscan, sophos, mcafee, eset.com, kaspersky, onlinescan, and more...
The device driver is not dropped and installed onto the system unless there is an active internet connection.
The virus may prevent execution of applications that perform an integrity self-check as a result of them being infected.
So my dear friend the easiest way to tackle this virus is to Remove above mention Virus Entry Doors from registry and Delete those .DLL files from system.
Sality Manual Removal Instructions
Below is a list of Sality manual removal instructions and Sality components listed to help you remove Sality from your PC. Backup Reminder: Always be sure to back up your PC before making any changes.
Note: This manual removal process may be difficult and you run the risk of destroying your computer.

- Type in "dir /A name_of_the_folder" (for example, C:\Spyware-folder), which will display the folder's content even the hidden files.
- To change directory, type in "cd name_of_the_folder".
- Once you have the file you're looking for type in "del name_of_the_file".
- To delete a file in folder, type in "del name_of_the_file".
- To delete the entire folder, type in "rmdir /S name_of_the_folder".

- Remove the "Sality" processes files: syslib32.dll, sysdll.dll, oledsp32.dll, oledsp32.dll, sysdll.dll, syslib32.dll
The best tool to remove sality variants is the kaspersky removal tool.
Plug your infected to another PC (slave) and rrin the tool.
