ALG.exe popup by Trend Micro Real Time Protection - can't remove

curtismjr used Ask the Experts™
Trend micro 2006 real time protection reports alg.exe in c:\windows folder  as part of sdbot.ik worm. Won't delete or quarantine it (have latest updates) even in safe mode. (The file is actually in the system32 folder.) Turned off system restore. (XP Home)

Can't shut down ALG process in Services - all stop options greyed out even when Manual is set.

Any way to remove this worm?

alg.exe in system32 folder is the legit file, anywhere else would be the worm or virus.

It's better to turn your System Restore back on just incase you need those restore points.


Here is the HiJackthis log. I tried removing the 023 - Application Gateway Mgr entry but it keeps coming back...Also, ran Msft Windows Malicious Software tool Quick scan turned up nothing - am running more complete scan now.

Sorry about the paste above - new to this and here is the link to the logfile (I think.)


For future reference, you can post the HJT log to and just post a link to the analyzed log.

I did this for you, and it is at:

You should remove the following entries with HJT itself:

 O4 - HKLM\..\Run: [webHancer Agent] "C:\Program Files\webHancer\Programs\whAgent.exe"
 O4 - HKLM\..\Run: [webHancer Survey Companion] "C:\Program Files\webHancer\Programs\whSurvey.exe"

Also, do you know what this is:

 O4 - HKLM\..\Run: [Blubster] C:\Program Files\Blubster\Blubster.exe SILENT

To fix the O23 entry relating to alg.exe, do the following:

 Start -> Control Panel -> Admin Tools -> Services

then find the Service named "Application Layer Gateway Manager (AppLayerGatewayMgr) " and right-click on it, select "Properties", then click on "Stop" to stop it, next change the startup type from "Automatic" to "Disabled"

Then reboot and run you AV program and it should be able to clean it up. In any case make sure alg.exe is not running in Task Manager.


Msft malicious software tool - Full scan shows nothing found, also.
If you look in the Services control panel, do you see "Application Layer Gateway Manager" there?

If you look at its properties, does it show as running from c:\windows\alg.exe ?

If so, stop and disable that. That file should only be in c:\windows\system32


OK - I finally was able to stop App Gateway Service (and Mgr was stopped) (it was running from c:\windows folder) - before it was greyed out - but this time (maybe it was the  reboot) Stop was available.

Blubster is an MP3 music sharing service -  I can take it off, also.

Popups from Trend have already dropped off - I'm getting a few "Access Denied" on WebEenhancer trying to install but will take it off, also. This looks like a successful fix.

Yes, looks encouraging.

You don't have to remove Blubster, I just wasn't sure what that is.

When all is said and done, I would suggest renaming or deleting the file c:\windows\alg.exe (not the one in \system32\) unless Trend already did it for you.

Good luck.


I tried taking the 023  - alg.exe entry off in Hijack this but it comes back when I do a Scan again. However, the Service is still stopped and no pop ups from Trend.


Ok - on deleting alg.exe - the odd thing is that it is not in the c:\windows folder at all (nor has it been when I first started looking.) I am "Viewing system folders and hidden files" in Folder options.

To delete the O23 Service, use the following method:

I think the alg.exe in c:\windows was there, but was being hidden by the virus. Once you disabled it, then Trend probably deleted the file itself (from c:\windows)

The version in c:\windows\system32 is legit, part of the XP firewall, so leave that alone.

The malware is getting sneaky these days, using names similar to real files, making it hardder to spot.


If it comes back as a Trend popup, I'll try theeldergeek suggestion - for now I'm leaving things as they are. Thanks for the help (and the possible explanation on the alg.exe not showing up - it was puzzling!)  I have to leave for a while - will check back with my client (and this post) tommorrow.


OK, good luck. Leaving the Service as is will cause no harm so long as it stays disabled. I am sure Trend warning will not return now that alg.exe itself is gone.

C:\WINDOWS\alg.exe <-- is this one gone?
Did you used explorer to look for it or you used "search"?
If you used "search", you need to reconfigure "search" function to search for hidden files?  by default it is not, and by showing hidden files via explorer folder options will not show hidden files when using "search".
You need to reconfigure search to search for hidden files:

Start > Search >
Click "all files and folders" then scroll down
and click "more advanced options"
put a check next to "hidden files and folders"
scroll up, type --> alg.exe
and click Search.

About the 023 entry:
Once the service is stopped, hijackthis are able to delete the service,
Open Hijackthis > Open Misc Tools Section > Open  "Delete an NT Service"
In the new window, copy and paste or type -->  AppLayerGatewayMgr
into the Open field and hit OK.

Or you can also delete it here:
Start > Run

sc delete AppLayerGatewayMgr


I used Explorer to look for it in c:\windows - didn't try Search.
Will try the 023 removal with Misc Tools later today. (Webhancer has been triggering Trend popups this am so I'm working on that. I Add/rem programs it and deleted the Program files but it is still out there - but alg.exe has not been OK.)


Removed Webenhancer with Ad aware and popups have stopped.

Great. I think you're pretty much in the clear now.
