There *do* seem to be Trojans that use this file name but they are much less common than some people are making them out to be. People are freaking out because they don't know how to set up their firewall! If this task is stopping you from accessing the Internet, that does NOT mean it's malware, it means your firewall settings are screwed up (blocking your Web browser or something), just go to the properties for your network connection and fix them instead of blaming MS or virus makers for your own incompetence.

i found a file in caps ALG.EXE-275708CF.pf in C:\WINDOWS\Prefetch. From what I read here, that's a no-no. I''ve just been hit by a wave of spyware attacks and this could be connected, but I can't say for sure.

That is microsoft process, but I think that can be dangerous, because I can't use google to search anything. Google said my system was infected by spyware,after I install Auto Yahoo, and then I can see Application -level gateway service & Marketing SOSftware.exe that I never seen before in my system task manager.

It's a meat eating turkey in disguise. Let this process keep running and watch what happens when you go to bed.

Lol at sam. This file is way too vulnerable and presents the opportunity for many malicious files to hop onto you PC , remove it if you are not firewalled. Otherwise, it will rewrite you registry or worse. Definately worth looking into more.

This is a useless MS file that runs when you don't want it to. Whoever wrote the description warning not to terminate it is an asshole. you will not loose you internet connectivity if you end this task.

There is nothing bad or malicious about this program. It. is: Application Layer Gateway service. Its used to forward application internet requests onto the ICS host, usually 192.168.0.1. Basically a proxy integrated in windows networks. Or NAT pretty much (Network Address Translation). I will say it again, its a windows service, not one bit malicious. Of course, if its in the System32 folder
