What am I to think with Google placing this unwanted cdm file on my computer without prior notification or approval?

Which browser were you using when this happened?

First Win 8 and Chrome but the same was created in Vista and Chrome. I wonder if I can delete the file or at least rename it to modify its use. Thanks.

From what I've been able to determine through research, the file in question is downloaded only by the Chrome browser while viewing YouTube videos. Just why that is, I don't know. Nor have I been able to determine for sure what its purpose is. If you don't want that file downloaded, at this point I'd suggest using a different browser. I have asked for assistance from others who use Chrome and Windows 8 or are familiar with these. Myself, I use neither.

Orange Blossom is 99% on it -

widevinecdmadapter.dll is loaded as dynamic link library that runs in the context of the Google Chrome web browser.

It is installed with a couple of know programs including Google Chrome Frame published by Google Inc, Google Chrome Frame from Google Inc and Google Chrome Frame by Google Inc.

The file is digitally signed by Google Inc which was issued by the VeriSign certificate authority (CA). This particular version is usually found on Windows 7 Home Premium (6.1.7601.65536).

 

Only problem is that Norton will kick back when it installs (false positive).


Solution:  I'm going back to IE.  As for Chrome, I'm not going to be green and recycle....it's going to the dump to get burned up!
 

P.S. I never have knowingly used Chrome, and I never intend to ........... (even to experiment)

And the thing about Google Chrome, especially if one dual boots, runs virtual machines, or has more than one computer, if the user is signed into the browser (with their GMail credentials), the profile will be spread across every computer one has & logged in. Even those that are borrowed & an account setup for guests (not the standard guest account), unless the Administrator has defined strict permissions, this will install on these too. On my Windows installs, I have Emsisoft Online Armor Firewall software, so it must have been treated as safe. I'll need to check when I get back into Windows. 

 

Bookmarks, add-ons, everything syncs, the exception being Linux OS's where some things won't sync exactly. 

 

Similar to IE for Windows 8 or 8.1 when signed into a Microsoft Account, so it's a matter of which you trust more. Personally, I fully trust neither & rely on security & safe computing practices to protect myself. 

 

I didn't really want to make the switch to Chrome, having been a 5+ year Firefox user after IE8 crippled my XP SP3 install (after MS sent me an invite to "improve" my Windows experience). However in the last year to 18 months, every Firefox release was getting slower, and I don't have patience for a slow browser, so I made the change on a "trial basis". 

 

That trial basis quickly became permanent, as Chrome is the fastest browser that I've ever used. Is it perfect? No. But neither are the others. At the current time, Chrome offers me the best balance between speed & security & until the day comes when that changes, will stick with the browser. However, I feel that of the three, when it comes to trust, Firefox is likely more trustworthy, as they're a non-profit corporation. Note that I stated "likely" & not certainly. Because I simply don't know. 

 

Fortunately, I use Linux Mint 17 90+% of the time I'm online, so don't fear infections. However I do have a similar file, w/out the .dll, it ends with .so. And was added on 08/08, so that was recent. Must be something new, as I was watching YouTube videos way before then. 

 

However, no matter the browser to access the content we want, chances are, there's always going to be some object needed to do the job, or to provide a better experience. Or maybe even collect data on the content we view, so that it can be delivered faster, offer the type that matches what we view, or most anything we agreed to when accepting Google's services. There's no 100% free ride here, even if it's not a monetary one. 

 

We can only make a choice for a browser & hope for the best. Since on Windows 8 & 8.1 OS's, IE is running anyway, it may be the best option for some. I say this because even though I don't use the browser on the OS, CCleaner still manages to find quite a number of IE files to delete. Have done most everything except disable the browser through the "Turn Windows features on or off" panel (not recommended is the result when checked). There is now an Adblock Plus option for IE to greatly reduce ads & like other browsers has some controls. 

 

All you can do is try different browsers & determine which is best for your needs & see which is the least intrusive.

Oh baby mine! It does appear that noknojono has flipped the rails (seemingly in a rage) and is going to junk Chrome. Don't forget to empty the ol' Recycle Bin there noknojono! It might come back at ya and bite ya right on the face!!!  :-)
