Remove Play-bar.net(PlayBar) Redirect Activated by Stopblock.me/wpad.dat

Infected with Play-bar.net? How frustrated.

If you have Play-bar.net on your computer, you may have the same experience like below:

When I open internet explorer it opens one of these 3 pages even though the default start page is google website:
esurf.biz
play-bar.net
cdn.freefacti.com

I noticed that in LAN setup the option "use automatic setup script" was activated with the link:
hXtp://stopblock.me/wpad.dat?8c25bfbaf19919a7d161d189738546fd39884

I deactivated the checkbox and deleted the link but it keeps appearing.
