1) BitDefender 2010 products require a medium to powerful PC to run smoothly. Recommended system requirements for running them are the following:

•Windows XP SP2, Vista, Windows 7
•Intel CORE Duo (1.66 GHz) or more powerful processor
•RAM: 1 GB (Windows XP and Windows 7)
           1.5 GB (Windows Vista)

2) Choose the suitable BitDefender 2010 product which is compatible with your Operative System, i.e.: BitDefender 32 bits for 32 bits Operative Systems or BitDefender 64 bits for 64 bits Operative Systems.

3) Have the appropriate NET.Framework which is suitable for your Operative System installed in your PC before installing BitDefender 2010. This is required to run the patch by BOX 3.0A. If you want to determine that the appropriate NET.Framework is already installed in your PC, Go to Control Panel => Add or remove programs => Check there which NET.Framework you have installed. After installing NET.Framework restart your PC.

4) You cannot have two antiviruses (AV) installed at the same time. So if you are going to install a BitDefender 2010 product you must uninstall the AV you currently have, including old BitDefender versions or any BitDefender 2010 which you may have installed and found it is not working due to the fact that you have applied a different registration procedure from the one described in this post (search for and delete any traces of BitDefender and Softwin in your HDD and in your Windows registry). It isn't enough to disable the current antivirus because there could be AV or Firewall services running in the background which could impair the correct installation of the new BitDefender. After uninstalling the old AV, restart your PC.

5) Windows Firewall must be disabled. After disabling it, restart your PC or in case of BitDefender Internet Security or Total Security, let BitDefender do it for you (tick the corresponding box when installing it). If you are going to install BitDefender Antivirus 2010 after its installation, patching and first update, it is recommended to re-enable Windows Firewall and adjust its settings to allow BitDefender to go into the net to perform futures updates.

6) Uninstall any other third party software which may conflict with the future services to be rendered by BitDefender (firewall, antispyware, antispam, etc.). After uninstalling such software, restart your PC.

7) Windows Defender (Microsoft AntiSpyware) must be uninstalled and/or disabled. After uninstalling and/or disabling it, restart your PC.

8) In case of Windows Vista and Windows 7, disable User Account Control UAC). After disabling UAC, restart your PC.

9) After having made the above adjustments but before installing the chosen BitDefender 2010 product, don't forget to create a restore point which can be useful in case anything may go wrong with BitDefender installation and/or its future operation.
