What is this file that repeatedly re-installs itself and why is it trusted by Norton

The details of a file installation identified by Norton Insight is pasted below.

Why is this file trusted when there are so few Norton users (less than 5)?  Do you know who is installing this on my computer without my permission and knowledge?

When I rename it or delete it, it gets re-installed somehow.  Sometimes it makes the folder in which it is installed inaccessible by me, on my own computer, with full administrative rights, after I rename it or look at it with the “locate” button in the File Insight popup.

I have never knowingly requested or installed a content decryption module and have no idea what this is for.  It seems rather suspicious.  I wonder if it is a tool for someone to acquire information from my computer.

Do you have any more information on it?

Thanks.

The file is a component of Chrome that allows the browser to play protected content:

hi Sveinn

I've noticed on other people's laptops when Google Chrome is installed from some locations a number of PUP's are bundled with the download. Whilst not necessarily dangerous they can become a pain. My niece installed it on my sisters laptop either on purpose or by accident where a number of programs were installed including ironically Norton 360.

One of the programs changed her home page and search provider. When I looked in the list of installed programs it was there.

I uninstalled all the unwanted programs with Revo Uninstaller and was able to return my sisters setting and laptop as she wanted it with no subsequent trace of the programs.

All -

Thanks for the information.  The .dll does appear to be automatically installed by Google Chrome.  I guess I will get rid of Chrome.  I've been using Firefox lately anyway and I like it better.

The thing that kind of bothers me is that Norton Insight indicates that the .dll that keeps being re-installed is used by less than 5 Norton users in the entire world. 

Why is my installation of Chrome so special?  Is Norton Insight not working properly?  It seems like there should be millions of users.

hi Sveinn

I do not know exactly the workings of File Insight nor Download Insight just the general description given to us all despite trying to find out more of how it "makes up it's mind". I have not had any program which Norton Trusts cause any problem with my devices however, as above they can perhaps be a pain.

I have a several programs which Norton says it is used by less than five users in the Norton Community when I have it installed on four devices so I am the only user with the program installed

It does improve with age though!

I will not have anything Google purposely installed on any of my devices although it is upto each person to decide what they have on their computers.

Hello

If it keeps reproducing itself, then it becomes a new file again.. Since it's used in Chrome, then it is trusted. If you don't delete it, then it has a chance to build a reputation and get older. Thanks.

For known trusted programs, the number of users is not really a good metric for determining whether you should be concerned about a file or not.  In these cases the file is almost certainly already submitted to Symantec for whitelisting, and has already been trusted.  I would not abandon Chrome simply because it includes plug-in components.  Firefox does the same thing - I often see Norton popups for newly installed .dll files for Firefox components.  It's just the way browsers work these days with new ways of providing content.

FWIW ~ CCleaner > Startup > Google Chrome > Wildvine Content Description Module > you may disable the Plugin
