Based on Microsoft Silverlight, New Player Features Enhanced Dynamic Streaming, First-Time Use for Macs. Silverlight is designed for delivery of cross-platform, cross-browser media experiences inside a Web browser. It is expected that Netflix members who watch movies and TV. More than 1000 downloads. Plataform for Firefox in which we will have access from our Mac to all the web apps.
And with Safari unfortunately, one can't select what plug-ins they have and simply disable the one not commonly used, so every web site you visit you have Silverlight enabled, so that makes any site able to hack your machine through Silverlight's insecurities. You can choose to use Firefox instead, it has the ability to disable plug-ins on a individual basis, so you can turn off Silverlight when not on Netflix. You can also read here about using NoScript with Firefox, which will disable all scripts unless you specifically approve for each site, instead of the other way around with Safari.

Silverlight doesn't exist as an Internet Plug-In. It functions as a standalone application so far as I can tell.
I don't have a NetFlix account to test, so do you know that what you download from NetFlix lives in the Internet Plug-In folder? Even if it does live as an Internet Plug-In it would not be in use when one is not using NetFlix. So, I'm not sure why you consider it a problem.
Nor do I understand how it relates to malware. I guess your information blew enough smoke to confuse the OP into thinking it was meaningful.

Even if it does live as an Internet Plug-In it would not be in use when one is not using NetFlix. It's a plug-in and any web site can call it just like it can Flash or Java or Quicktime.
So, I'm not sure why you consider it a problem. Nor do I understand how it relates to malware. Because there are security vulnerabilities for Silverlight like there are for Flash and Java which malware like Flashback compromised 600,000 Mac's. So if you have it always enabled, it's on for every web site one visits, malicious or not. Safari doesn't give a individual plug-in turn off method, it's all or nothing approach so one can't tailor the plug-ins to suit one's browsing preferences to remain more secure.
I guess your information blew enough smoke to confuse the OP into thinking it was meaningful. No smoke or confusion on mine or the OP's part. Read my Hardening your Mac, it's got me past MacDefender and Flashback malware by reducing my exposure window. I'm sort of puzzled because I have Silverlight on my system but there is no Silverlight plug-in. Is this just a special version for NetFlix that runs as a browser plug-in?
There are security vulnerabilities all over the place, but hardly enough to create a major scare over something. I've yet to have any problem with Silverlight which has been on my computer now for several years. I even used it quite a while back for NetFlix movies when streaming was a freebie. As usual I think you overstate the issue. Kappy wrote: I'm sort of puzzled because I have Silverlight on my system but there is no Silverlight plug-in.

Far as I know it's a clone of Flash like, with DRM capability. It's the same, no special version except for the DRM.

Look in your 'Hard drive'/Library/Internet Plug-ins folder, it's not in your Users Library or System/Library folder. If you want to uninstall it, the instructions are here I've yet to have any problem with Silverlight which has been on my computer now for several years. I even used it quite a while back for NetFlix movies when streaming was a freebie. Perhaps you need to run a check it's likely outdated and vulnerable. П™‚ There are security vulnerabilities all over the place, but hardly enough to create a major scare over something. The OP wants to reduce their exposure window to Microsoft software, since they can't not use it and use Netflix, so I gave the answer for disabling it for all other sites but Netflix. Seems the OP is well pleased with the compromise solution, no scare campaign as there isn't anything attacking Silverlight on Mac's yet far as we know.
Of course we didn't know about Flashback until it was already 600,000 Mac's strong. Apple Footer. This site contains user submitted content, comments and opinions and is for informational purposes only.

And this usage stays that way more or less throughout the movie? The main thing I can think of is that you have auto-updating turned on and it's downloading/installing/preparing to install updates for things, although I don't know that such a thing would require much cpu usage.
Just to confirm, task manager says that chrome and/or silverlight is using the cpu? And not some other program that is hogging your resources? Because I know that windows update can take a fair bit of resources when updating (although in my experience it's mostly hard drive stuff), and that by default it's auto-updating. Other than that I can't think of much. Maybe if you have a lot of other flash videos open or tabs or something.
