Thank you for your help.
The problem is presented, for example, running Media Player Classic or BSPlayer. But also when I try to modify the file's name of the video, or when I try to see their properties (right click). Only VLC works to play the videos, I don't know why...
Since three or four year I use the 3-User McAfee VirusScan Plus in Spanish. But this problem I only have it in one of the three PC where I have installed VirusScan, and only with the new version 14.0.306.
I have uninstall and install again the McAfee. And I have uninstall all media program and codecs too. But the problem with the mcshield.exe continues appearing when I want to work with the files of videos (renaming, etc.).
After running the MVT, this program detects these problems:
Missing files with the program recently installed?
How can I see what files are missing and how do I recover them? (McAfee is just installed!)
After run by second time the MVT, the problems continue there.
Missing files explanation: As the MVT it doesn't recognize the Spanish language, it expected that the files are in the folder "Program Files", but they all are in the folder "Archivos de programa". There are not problems in the SecurityCenter.
The file <mpfsbt.inf> that is reported missing in the Personal Firewall, is really missing.
I uninstall and reinstalled the McAfee and that file is still missing.
When you uninstalled it did you use the MCPR removal tool here?
Did you try to do the playing etc with Mcafee uninstalled?
Re the missing file this an issue with MVT at the moment so we were told today.
Thank you again for your answer and orientation!
Yes, I uninstalling using MCPR. All folders were eliminated and the Registry was clean.
With VirusScan uninstalling or simply deactivated, all in my machine works fine and good, and I can use videos with my favorite programs.
But that more I worry about it is that in the other two PC (my wife's and my daughter's computers) where I installed VirusScan, they can work (playing, renaming, moving, deleting) perfectly the videos (with VirusScan installed and active!).
I am not able to discover why I have this problem exactly in the PC that I use.
P.S.: Sorry for my basic English.
I would suggest contacting Chat support via the link in useful links above. I feel there might be installed software that is clashing like did you before installing Mcafee have another Antivirus/firewall installed?
I have used McAfee for years and years. Also, this PC I have formated it and reinstalled all from zero few months ago, installing VirusScan 9. Neither I have activated the firewall of Windows!
Well, I will contact Support for this problem.
Thank you again, Peacekeeper!
Solved problem! After uninstall one by one all my installed programs, when I uninstall Nero (burning program) I was able to play (and work) the videos without problems with the antivirus.
Searching an explanation of this, I found that NeroScout is an application that indexed all the media files in the PC. I suppose that when NeroScout works with the videos, the mcshield.exe begins to work on all that process, using 99% of CPU for more than a minute.
Disabling NeroScout by the control panel of Nero, don't work.
Now I will look for a solution with the support of Nero. But I wanted you to know about this problem of VirusScan colliding with NeroScout.
Thank you for your support!

Thanks for posting this information! I'll be sure to make my Tier 3 engineers aware of this. I didn't know Nero did that!
