What is alg.exe doing on my computer?
The alg.exe executable allows applications (such as IM clients, RTSP, BitTorrent, SIP, and FTP) from a client computer to dynamically utilize passive TCP/ UDP ports in communicating with known ports on a server. This allows software to access applications that reside on another computer even if there is a firewall.
The alg.exe file’s absence would cause the security protocols to block communication ports, or for network administrators to consciously open numerous ports on the firewall that would create immense network vulnerability and potential threats.
The development of alg.exe was done within the context of computer networking architectures, where it is associated with the Application Level (or Layer) Gateway Service, as well as Network Address Translation, and is designed to supplement the firewall protection of a network.
alg.exe is a system process that is needed for your PC to work properly. It should not be removed. Check your system now to identify unused processes that are slowing down your computer.
