Hello I spent whole day for discovery websockets problem on my new lenovo. Main issue - websockets not work in any browser launched on new laptop (Lenovo Y50-70) but work on other PC with similar software installed (for example this page: http://www.websocket.org/echo.html ). I have installed ProcessMonitor application and found VisualDiscovery.exe handle all traffic for WEB browsers. When I have stoped VisualDiscovery system service - all WEB application start work properly. 
I have uninstall C:\Program Files (x86)\Lenovo\VisualDiscovery\  from my laptop and now all work fine.

But I am verry unhappy about this application, and can't found any description about it in the net and lenovo documentation. Why lenovo install it ? And which service provide this application ? Where I can get necessary info about it ?

I can confirm to alexcn's claim.

Visual discovery messed up my websocket.

before, i always faced websocket received packet failed test.

After uninstalling VisualDiscovery, websockets worked fine.

Lenovo needs to get rid of this VisualDiscovery. I spent 4 days trying to figure out this.

I'm a new Yoga 2 13 owner.

alexcn, sorry I missed your earlier question.

If you do not find VisualDiscovery useful, it can be uninstalled via the Control Panel's list of Programs, or disabled. Remember to reboot afterward.
