Im having the same exact problem. It just started happening about a week ago and it has only been Hulu and one video on another website.
I found that this occurs for only some videos on Hulu, not all.

Have either you tried with netguard a firewall setting disabled?
Yes, I just tried it out and disabled them and this did not seem to solve the problem. Unless my PC needs to restart for this to take full effect than it does not solve the problem. (At least for my particular situation) Should I try and completely disable the firewall and perhaps each setting at a time and see what happens?
Try a reboot though I would not have expected it needed to,. try also a reset of the firewall to defaullts then if no help wait for Dinz to comment. There is a netguard fix for mcsvhost errors soon so that may help.
I assume chrome has full access?
I am having the same problem with the McSvHost.exe error. I figured out a temporally solution without rebooting your system. Open your McAfee.
Click on Firewall: On
Click on Settings
Click on Restore Defaults
Click on HOME
This will fix the problem and you can get back on the web without rebooting. But I still need to get a fixed solution. I should not have to do this everytime McAfee wants to double check for updates or whatever is doing to causethis problem.
I still need a real Fix.
The temporary solution you mentioned actually works.
Two friends of mine also have the McSvHost.exe issue, and I'll be passing your temporary fix discovery to them in the morning.
McSvHost.exe causes a ridiculous amount of CPU spikes, leading to "dragging/lagging" whenever I'm playing a game, video or music. I never had this issue while I was with Nortons Antivirus. It would be nice if McAfee can address the issue and release a patchfix.
Just a note - I have never used "hulu" before in my life. For me the issue occurs while browsing normally, I've spotted it guzzling up to a maximum of 86% CPU at one point.
Thanks again lftqba1980.
