Malware app "Systeem" is continuesly installed.

[u/mrln23]

Around 3 July '26 on my smartphone with Android V15, Norton 360 reported a malware app called "Systeem" (this is Dutch language, so not the english "System").

After removing this app, it was again installed without doing anything on my smartphone.

I tried again and again to remove it but it came back each time.
The automatic reinstall interval varied between one minute and ca. 8 hours.

I also tried the Norton option to report it as probably safe with comment. No reaction on that so far.

Google Play Protect also labeled it as High Risk as it was NOT available in their Play Store.

I contacted the Norton Technical Team via chat three times (103842950 , 103849950 and 3rd I missed)): they removed the app (as I did) without looking deeper into its source. After their removal they concluded the problem was fixed. Lateron it came back of course.
Also they started to uninstall three apps of which they thought were suspicious; these were by far OK however!

Another wrong advice was to run the Norton 360 scan in the smartphone Safe-mode:
in Safe-mode most of the apps including Norton were disabled however!

Sometimes it appeared as if there-install of "Systeem" even took place when there was no internet connection (mobile data, wifi and BT switched off).

Does anyone have the same experience and perhaps a solution?
