applications running on your system by means of CPU load, memory usage and
hard disk use.
You should be able to pinpoint the applications that are causing the system to

“Performance Monitor” (p. 165).

Any computer has programs or applications 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 application you forgot to remove.
Important
If you suspect a program or an application to be an essential part of your operating
system, do not remove it and contact Bitdefender Customer Care for assistance.
