I have found PVSonyDll.dll in Windows\System32 and Programmes and Features in my Windows 7 refers to it as being an "uninstallable" programme and I wondered what it was, the name certainly gives no indication as to its use. See here for an example:

http://www.spydig.com/file-diagnosis/PVSonyDll.dll.html

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 as per the link above.

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

http://www.driverchecker.com/testspydig/dll/PVSonyDll-dll.html

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. In the meantime I have renamed it and so far have noticed no ill effects

What does "Programmes and Features" do?
And why is it pointing out that this is "uninstallable"?

This is Windows 7 term for "Add/Remove Programmes". It indicates that the programme can be removed.

Thanks for the links... I'll check them out. The reason my post appears elsewhere is because it was moved and I had no idea there were replies and I never knew until you pointed it out.

Thanks and regards

In that case, thinking it is only there for informational reasons.

So long as it is not malware, I wouldn't worry about it.


My uninstaller says:

Quote:

For uninstall items of Windows installer without uninstall strings - MyUninstaller now automatically generate the uninstall strings and allow you to uninstall these items.

... so maybe that will allow an uninstall?

Thank you therube... I have renamed it in the meantime. So far nothing untoward has happened in the system so I'll give it time then delete it.
