Jord is quite right here. We need to find out if the monitoring program is allowed to see all running processes.
If it is, then there are some hidden processes running. By my understanding, any process that hides itself from root is a malicious one.
Thanks Guys, It’s unclear if System Monitor Lite shows root processes. It
has a request root option, but only on it’s App Cache calculator page, so
it’s unclear if that is only applied to process monitoring also, or only
the Cache calculations.
Can anyone recommend a simple process monitor I could use that does monitor
You could try OS Monitor and check the “Expert Mode” box in the settings. For me, it means that the number of checked processes rises from 45 to 160, so I guess that it captures all system (root) processes.
Isn’t your option 2 more serious than your option 3? Installing the OS only “refreshes” the system files, whilst a hard reset also erases user data such as photos, music, etc. stored on the internal storage, or am I mistaken?
Yes, that sounds reaoonable. However, if the phone is infected so that hidden processes are running, the logical first step for me is to get rid of everything installed after the phone left the factory, i.e. a hard reset. If the problem still persists, the infection must have affected the system files, in which case reflashing ought to fix it.
Pure guesswork from my side now (since I’m not knowledgeablem enough), but yes: if we suppose that there are some protected, read-only image files stored on the phone that cannot be corrupted, then of course a hard reset ought to be enough and my 3rd step above will be unneccessary.
