FILENAME: Alg.exe.
PROGRAM NAME: Application Layer Gateway.
DESCRIPTION: Part of Windows XP that provides support for
Internet Connection Sharing (ICS) and Internet Connection Firewall (ICF).
RECOMMENDED ACTION: If a third-party firewall warns you that
ALG.exe wants access, check to make sure you're not double-firewalled.
If you are, disable ICF. If you are using neither ICF nor ICS and are
warned that ALG.exe is trying to access the Net, deny it.
A Trojan horse or worm may be trying to use it as a backdoor.
