Hi. My taskmanager displays "firefox (7)", although only two tasks are open. In addition, 47% of the 8GB of RAM is expected to be used.
including 42 background processes are listed that all say nothing to me. An hour ago, the laptop was extremely slower for a short time than usual, while websides like Facebook loaded in about 30 seconds. Avira is installed and displays "protected".
Should action be taken in this case?
This is normal for web browsers. A task does not always mean a window! When you open the browser, security functions etc. Are also loaded with their own processes.
A scan for malware with malware bytes will not hurt.
Antimalware and Adwcleaner are both recommended.

Tab is not the same task. Your computer runs many other processes in the background (such as when you move your mouse). Has he suddenly slowed down?
