PVSonyDll.dll file in Win7... threat or not?

Microsoft Excel 2003 (full product)

Specs: Windows 7/XP Dual Boot, P4/3.1 3gig
I have found PVSonyDll.dll in Windows\System32 as an "uninstallable" programme and I wondered what it was, the name certainly gives no indication as to its use. See here for an example:


I did a bit of extensive Googling and generally it is described as a "malicious file" which can be used by hackers to compromise a computers security.

By the same token however this site lists it as a downloadable .dll:


My question therefore is this "is it a malicious file or is it a required .dll bearing in mind that I have no Sony products on my system BUT I do use NVIDIA and this file is also referred to in that connection.

PS: The product shown above is Microsoft Excel. This has nothing to with MS but I can't delete the product.

It seems to be related to Sony this PVSonyDll.dll in Windows\System32.

If you never used anything related to Sony, you definitely have to remove it.

If Windows reports that it cannot delete the file, this indicates that the file is in use. In this situation, complete the rest of the instructions on this page, restart the computer in Safe mode, and then delete the file using Windows Explorer.

Right-click the file and click Properties. Click on the Version tab and click Company and see if Sony Corporation is named as the company of the file. If not, rename it and run your computer for several days. If you see no ill effects with the file renamed, then you can move it to another location and keep it there for several months.

Hope this helps.

Thank you for your help... I have in fact renamed the file and thus far there seems to be no ill effect. I'll leave it for a bit longer and than I'll move it to a USB stick until something does happen (hopefully not)
