Since few days ago I noted the laptop was too slow, after checking processes Analytics SDK is using more than 90% of the CPU. On the other hand I have no navigation at all, but the computer looks connected to Internet and to the network because I have SKYPE, but nothing else, no browsing at all. After I uninstalled all Mcafee products everything is normal, so Total Protection is responsible.
I have Mcafee Total Protection last version.
Check out this thread, and the temporary workaround that is updated on the first post. There is a fix coming from McAfee soon, though.
1) Open the Windows Start Screen or Start Menu, type "services.msc" and hit Enter to bring up the Services screen.
2) Double-click on ClientAnalytics, and change the drop-down to "Disabled."
3) Reboot your computer.
That will disable the service that is causing the issue until McAfee releases the proper fix for it.
