What Is Alg.exe?
The purpose of the alg.exe file is to allow applications, such as IM client software, FTP and Torrent applications to establish a connection between two computers using passive TCP/UDP ports over a server. This enables the user to access files and applications off another system, even if that system is protected by a firewall. Without this particular file, the security protocols would block all communication ports, forcing the end user to manually open available ports, which would leave the system vulnerable to malicious files and hackers.
