● The Minimum System Requirements for running Bitdefender are not met.
If your machine does not meet the Minimum System Requirements, the
computer will become sluggish, especially when multiple apps are running
at the same time. For more information, refer to “Minimum system
requirements” (p. 3).
● You have installed apps that you do not use.
Any computer has programs or apps that you do not use. And many
unwanted programs run in the background taking up disk space and
memory. If you do not use a program, uninstall it. This is also valid for any
other pre-installed software or trial app you forgot to remove.
Important
If you suspect a program or an app to be an essential part of your operating
system, do not remove it and contact Bitdefender Customer Care for
assistance.
