Agent.exe Locking Files Belong To Other Processes

Recommended Posts



I'm using "ClamAV for Windows" for a while now (from version 2.x?). Recently it was upgraded to version 3.x and then again to version, and this is the version which I'm currently using on my Windows XP Pro.


- Immunet 3.0 (

- Microsoft Windows XP [Version 5.1.2600], Professional, Version 2002, Service Pack 3, English


After that last upgrade of Immunet I've noticed stability issues all over my system. Took me few weeks to pinpoint the issue to agent.exe. Problem is visible specifically on shutdown and then on next start of some applications, ie Firefox.


The issue is that agent.exe blocks (locks) files of other processes like Firefox's or Skype's config files. Locking config files of other applications make them crash on their exit (ie: windows shutdown) and corrupts setup of some of them and re-configuration is needed next time they are started.


I've troubleshoot the issue thanks to small app called 'Unlocker' (http://www.emptyloop.com/unlocker/). Even when I've close for example Firefox, I knew Firefox couldn't write it's config back to disk, when I've change its setting or modified bookmarks. Initially I though that's permission issue, as when I was trying to delete a file I got 'Access Denied' error message on the files. It turned out that wasn't the case.


With 'Unlocker' I could see that even when Firefox was already closed and not running, agent.exe was still blocking bookmarks of settings file.


Currently my usage of Firefox or Skype is that each time I want to shutdown my Windows, I need to start 'Unlocker' on directories where other apps store their config files, be sure to unlock against agent.exe all their config files. Then close those apps, and then shutdown Windows. Skype is crashing very often during OS uptime and unlocking often doesn't really help to it.


That is really annoying and I'm considering to uninstall Immunet from my computer.


I've collected System Diagnostic Tool 7z archive and have screenshots from 'Unlocker' to show the issue. Please let me know do you need any more info.


PS. Should I just send 7z archive and screenshots (png) files to support at immunet, and that's all?

Blocking mode was always, and still is OFF in general settings in Immunet 3.0 on my computer. Yes, I've already sent files to support at immunet com and got confirmation email from Rob T. that issue was escalated to developers. I'm happy to help, so don't hesitate to contact with me (preferably via email, but this forum will do as well) if you need any more info.

Also what I've noticed, when agent.exe locks the files (checked via 'Unlocker') and it does for many apps which I'm using at the time I want to unlock all the files so I'm stopping Immunet service. Here is what I often get:


C:\WINDOWS>net.exe stop immunetprotect
The service is not responding to the control function.

More help is available by typing NET HELPMSG 2186.


Then I can see in 'Unlocker' that agent.exe disappeared from running processes, and service seems to be stopped anyway.


C:\WINDOWS>net.exe stop immunetprotect
The Immunet 3.0 service is not started.

More help is available by typing NET HELPMSG 3521.


Starting the service back looks alright:


C:\WINDOWS>net.exe start immunetprotect
The Immunet 3.0 service is starting.
The Immunet 3.0 service was started successfully.


That's more just an FYI than anything else.
