D'ya know Rick, there are occasions when I think I would have more success in doing the Times crossword than trying to decipher some of your queries :D

Can you put some meat on this one ?

A stab in the dark.....

facebook is banned in China? pages with facebook links result in a failed DNS lookup (DNS prefetching), generating an error?

Try Fanboy's social annoyance list, available for Ublock Origin and AdblockPlus. Or, if you use Firefox, turn off DNS prefetching.

Off to solve the Times crossword puzzle now  :wink:

Edit:

2 screenshots attached, see how all the annoying ads and social media content are blocked by uBlock Origin (Fanboy's annoyance list) and Ghostery.

I would boot up into Safe Mode with Networking and run a scan with the ESET Online Scanner.

http://www.eset.com/us/online-scanner/

Click on Advanced and check all of the boxes except Archives and the Proxy one.

You may also want to check Task Scheduler to see if you have anything on there that is trying to phone home.

Restore points to prior this occurring could also help but see if ESET finds anything untoward.

Check the timings of the error messages in event viewer with sites that you visit that include the facebook connection logo, see my first screenshot above. Open Tweaking.com main page and you will see the facebook connection icon, then check event viewer for the DNS lookup failure error. As Facebook is banned in China, the great firewall is blocking the DNS lookup.

Your browser will be attempting to do a DNS lookup for these in the background (Prefetching), so that in the event you click on the icon it will speed up browsing, in the same way it will prefetch links as well. I have outlined the solution above.

In Firefox, set "network.dns.disablePrefetch" to "true".

Well that is one way I suppose. I am suprised that Facebook had entries in your registry. Has it worked?
Hope you use Registry Backup  :wink:

No need use regbackup for facebook entries!

Everyone would be wise to remove to free up system resources!

No Facebook entries in my registry, I guess you must have installed something that put them there?

En lite of WIX.COM free Wen enterprise development being blocked; and now we know the reason is that Alibaba Mr MA is inviting small enterprises to market in China.

However, other webs develoment websites load nonsense and that is probably where it came from...
