What are these log files for?

We have a Windows 2008 Server running IIS, one application, and AV. It has c:\hostact.log size=380MB and a c:\hoststat.log with a size of 200MB.
What is generating these log files?
How do we disabled this logging?

These are not generated by IIS or Microsoft.  Use sysinternals process explorer to determine what application or process is writing to the file - once we know the app we can assist further.

When you open process explorer, use the icon that resembles a pair of Binoculars... or use the hotkey Ctrl+F(find) and type the name of the file... it will show you which process is presently running and has locked the file for use.

Neither filename shows up in Process Explorer and the logs continue getting updated.

Resource Monitor shows one of the files c:\hostact.log
System, PID=4 (along with most everything else).
Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

files accessed through a share will be locked by the system process (PID 4).

Try opening compmgmt.msc -> System Tools -> Shared Folders -> Open Files to see if the locked file is listed there

no open files either. I rebooted the server and the logs continue to update\grow. I used to have a notepad replacement that could open up large files but forgot the name and do not know of any legit programs to try.

More information. The server is a VM running on VMware and the AV software is Kaspersky anti-virus.

OK. I used Programmers Notepad and was able to open the files and now see what the log files are for.
thank you.
