I am having the same issue as other posts. Just started yesterday. No new add-ons in last 6 months. I have 2 Windows 10 computers, with MBA-E, on my small home office network. The other unit is not having a problem... yet. We have 10 computers at our main office and none have had an issue, however, they have not been upgraded to Win10. Most are Win 7. Most of them are also running MBA-E and all are using Google Chrome. HOWEVER... it started with an update to Rapport Trusteer Endpoint Protection. Everything was working fine until I installed an update download for this software yesterday afternoon.
