By not being familiar with the Corporate/Enterprise applications, I have no suggestions other than consulting your Support Team/or Service Portal. However here is a description from the McAfee Threat Center, in regards to the mentioned Detection W32/GetCodec - Malware - McAfee Labs Threat Center

You can also test the files on www.virustotal.com.
Yes peacekeeper, I did that, I test many files on virustotal.com but none of them was infected. I clearly think it was a false positive but I wanted to have your opinion. Could an antivirus made so many mistakes (more than 500 files)? Or is the non trial version of virusscan entreprise more accurate than any antivirus engine on www.virustotal.com?
See....How to Submit a file to the Labs for analysis: http://www.mcafee.com/us/threat-center/resources/how-to-submit-sample.aspx
Email file to: firstname.lastname@example.org and make the header of the email start with the word FALSE - for example FALSE: In-house file being detected by McAfee
When submitting samples via E-mail all samples must be packaged in a .ZIP file.
Additionally, any .ZIP file created must be password-protected using the password "infected" (minus the "") - using the basic or default zipping level - some compression software offers varying degrees. Failure to follow these guidelines will cause your submission to be rejected.
If you've done that properly an automated response should be received almost immediately, followed by a manual one, usually within 24 - 48 hours.
If you don't receive anything it either means the file was submitted incorrectly or the response is sitting in your Junk or Spam mail folders.
**If they respond that it is an infection and you are sure it is not, reply to that email immediately ( to email@example.com ) and insert the word 'False' (minus the '') in front of the header, but keep the rest of the header intact.
If you have 500 MP3 files then those messages indicate not 500 malware detections but one malware detection repeated 500 times.
You haven't said anything about any messages you get when running any of these files. Have a look at the Microsoft entry for this malware detection and see if you recognise any of the illustrated dialog windows that would confirm the files have been tampered with by malware. The extension may be MP3 but if infected they will have been changed to required WMP.
Peacekeeper, i tested my files with MalwareBytes as you said, but again it found nothing, no virus w32/getcodec in my music. I will send some samples tomorrow to Mcafee Labs.
Hayton, yes it should be the same malware detected many times. I didn't say anything about any messages i could get when running those files because there isn't any dialog windows asking me to download a codec. I test with VLC and with WMP, it's the same, there is nothing at all, everything looks OK !
