Security Event Log

Hi,

Using Server 2008 R2, Windows 7 Pro

On the client machine when I closed a legal management software i use.:

Seems like the following error is logged:

Could someone please indicate what does it mean.
Also a message pops up saying:

It means that something is wrong with the file

\Device\HarddiskVolume3\Windows\System32\l3codeca.acm  

and it may be caused by a disk starting to fail or by someone deliberately tampering with the file.

I would run full hardware diagnostics on the motherboard and hard drive, and also make an image of the machine ( or full backup ) so that it can be replaced if needed.

 I hope this helps !

Apparently it is a codec for playing back  a specific type of video/audio.

You might consider renaming it to l3codeca.acm.old and see if the problem goes away
