NIS 2012 slowing down Visual Studio 2010

OS: Windows 7 Pro 64-bit SP1

NIS ver: 19.2.0.10

Visual Studio 2010 SP1

 

With NIS 2012 installed, whenever I write/change something in my C# source code, I will experience a slow down in the Visual Studio 2010 editor when I am moving my cursor, scrolling, switching between opened files and closing file. The problem will completely go away if I turn off the Antivirus & SONAR Protection.

 

It is the exact same problem as described in this topic:

I am pretty sure this is specific to NIS. I have actually used several security software before:

 

McAfee Internet Security (comes with my Dell laptop): No such problem.

NIS 2010: Slowdown in VS 2010.

Avira Antivirus Premium: No such problem.

NIS 2012: Slowdown in VS 2010.

 

Although the slowdown is not up to the level of unusable, it is still very annoying. Is there a solution to this problem?
