1. PREPARING FOR INSTALLATION
Before you install Bitdefender Internet Security, complete these preparations
to ensure the installation will go smoothly:
● Make sure that the computer where you plan to install Bitdefender meets
the minimum system requirements. If the computer does not meet all the
minimum system requirements, Bitdefender will not be installed or, if
installed, it will not work properly and it will cause system slowdowns and
instability. For a complete list of system requirements, refer to “System
requirements” (p. 3).
● Log on to the computer using an Administrator account.
● Remove any other similar software from the computer. If any is detected
during the Bitdefender installation process, you will be notified to uninstall
it. Running two security programs simultaneously may affect their
operation and cause major problems with the system. Windows Defender
will be disabled during the installation.
● Disable or remove any firewall program that may be running on the
computer. Running two firewall programs simultaneously may affect their
operation and cause major problems with the system. Windows Firewall
will be disabled during the installation.
● It is recommended that your computer be connected to the internet during
the installation, even when installing from a CD/DVD. If newer versions of
the app files included in the installation package are available, Bitdefender
can download and install them.
