Update caused NIS 100% disk usage & Thumbnail Handler Extraction Host

Hi Symantec,

Two days ago, my laptop's NIS 2014 updated itself, and since yesterday, i can't use my win8.1 laptop.

Upon booting into windows, it busies itself with task manager showing NIS taking up 100% disk usage.

When I end-tasked NIS, Thumbnail Handler Extraction Host multiplies...

I'm in safe mode now, removing NIS...

If later, i run into problems with a new installation of NIS, then I might need a solution......

Fingers' crossed now...
