Alg.exe Process Summary:
Process Name: Application Layer Gateway Service
Owner/Developer: Microsoft Corp.
Part of : Microsoft Internet Connection Sharing (ICS)/Windows Firewall
Valid Location : C:/Windows/system32/ (How to Find Process Location)
Virus/Spyware Threat Alg.exe can be targeted – Needs to be in its Valid location.
Alg.exe is a core process of Microsoft Windows OS XP as well as Windows Vista. Alg.exe facilitates the connection of various 3rd party application and programs with the Internet. Examples of such programs are your FTP software, IM clients etc. It works as a supplement with Windows Firewall and lets the applications communicate with the server via various TCP/UDP Ports present on the computer.
If you terminate the Alg.exe process the computers security protocol would shut down all the communication ports on your system and you would lose your internet connection.
Where is Alg.exe located:
The location of a specific process lets you know if the process is genuine and isn’t being run by a virus or spyware. The correct location of Alg.exe is C:/Windows/system32/ …… If located in another location chances are your computer is infected by a malware, which is trying to imitate the Alg.exe process. You can check the location of this process via the Windows Task manager in the “Processes” tab.
You can read the more about how to locate a processes in Windows XP and Vista. As shown in the image below, in Windows Vista you can simply right click on the process name and get to its location. Its not the same in Windows XP
How to confirm that Alg.exe on your computer isn’t compromised by Malware:
There are a few steps to check if the process you are looking at is a genuine process and isn’t a spyware.
The best way to do this is to use Sysinternals Process Explorer. It has a unique feature which lets you check if the process is indeed genuine. You can read more about downloading and using the Process Explorer here.
Open Process Explorer and locate Alg.exe in the listed processes. Right click on it and click on “Properties”. Click on the “Image Tab” in Properties window.
Here it shows both the actual location of the process as well as tells us if the process has been digitally verified with the owner (in this case Microsoft Corp).As seen it says its not verified. Click on the verify button and Process Explorer will cross check with the Microsoft servers if the file that is being compared is a legitimate process and hasn’t been replaced or compromised in someway. Each process has a unique digital signature and if Process Explorer shows that the process has been verified you can be fairly certain that the process you see running is legitimate.
You can also view the verification status of a process in the main windows of Process Explorer. As you can see that the process has been verified, ason the extreme right corner, whereas others have not. Hence we can conclude that the Alg.exe process that is running in our Windows is genuine.
If you have questions or more useful information about this process, fire away in the comments.
Provides support for 3rd party protocol plug-ins for Internet Connection Sharing and the Windows Firewall.
This service also exists in Windows 10, 11, 7, 8 and Vista.

About once a week when I boot up, a file named alg.exe attempts to access
the internet. I have it blocked. Is this part of Windows XP or is it some
sort of spyware?

Application Layer Gateway service is a component of of Windows OS. It is
required if you use a 3rd party firewall or Internet Connection Sharing
(ICS) to connect to the internet. Do not end this program in task manager —
you will lose all internet connectivity until next restart or login.
The alg.exe file is located in the c:\windows\System32 folder. In other
cases, alg.exe is a virus, spyware, trojan or worm! Perhaps try a spyware
checking app, unless you have ICS enabled.

I have not noticed any ill effects from blocking this program. I am using
McAfee Firewall, not the XP firewall. I don’t know if I’m using ICS or not.
There is really no way for an ordinary home user to know what all of this
is, nor is there any way to determine which files should or shouldn’t be
accessing the Internet. With all of the security problems out there today,
both within and outside of Windows, I tend to err on the side of caution.

Application Layer Gateway Service
Part of Windows XP.
If you do not use the «Windows Firewall» or «ICS»(Internet Connection
Sharing), it can be safely disabled using «Administrative Tools»
«Services»
If you use either of the above, leave it enabled.
Be aware that Spyware files often use names similar to native Windows
files.
