Bitdefender & Explorer.exe

Hello all ,

This is my first topic on BitDefender Forum so excuse me if I posted in the wrong section , I have Windows 7 Ultimate x64

installed on my pc which is GA-G41MT-S2P , 4G RAM

When I installed BitDefender Total Security 2013 x64 the problem began :

When I open " My Computer " the window hangs for more than 1 minute , and if I clicked on anything , explorer.exe crashes .

Note that this problem (Explorer.exe hangs and crashes) doesn't occur only on startup , it happens randomly (many many many times)

and it's not only the problem with opening and exploring folders , when I open start menu and click on any program menu , all files ( like

files under accessories submenu are shown white ( like it's unknown extension ) , then when I try harder to open more sub menus , the

whole start menu and taskbar goes unresponding .

I succeeded in knowing what causes this annoying problem , it's BitDefender

HOW ?

when I uninstalled it , the problem disappears , when I reinstall it , the problem comes back .

here is a list of programs which I installed on windows :

-Malwarebyte's anti malware ( as an alternative untill I can figure out the resolution)

-PowerISO

-Nero12

-TuneUpUtilities2013

-Real Player

-WinRAR

-Microsoft Office Professional Plus 2013 Preview

-Adobe Reader , Shockwave and Flash Player

-Google Chrome

, I tried disabling Active control in bitdefender , but nothing is fixed .

I tried adding explorer.exe to processes exclusion

I tried with a program called ShelEXView and I disabled all non microsoft objects , but noting is fixed so I re enabled what I disabled .

I have been googling and trying to find a resolution to this annoying problem , but noting helped me until now .

It'll be appreciated if you guys helped me because I can't do without BitDefender TS .

(Sorry for horrible English)
