At the moment the BitDefender 2008 and 2009 products are not fully compatible with Windows 7.
On my Windows 7 BETA,bitdefender antivirus 2008 and 2009 are not fully compatible with it.
here is some issues for BitDefender:
1.BitDefender disabled antiphising program on nternet Explorer and Firefox.
2.I can't turn on Anti Spam Program Control.
In the final windows 7 version,BitDefender 2010 product will be fully compatible with Windows 7.
