DSMLawmo is a Samsung system app that is preinstalled, it is not malware but it does have many of the characteristics of malware likely leading to a false positive detection, the description is:
"DSM states for "Dedicated Security Management " Which allows this app
to get a full control over the phone using voice channel only...
Dsmlawmo is to get full control over the phone, track it, reset and
stuff like that. It's probably to control and repair the phone
remotely when calling cs"

A simple Google search will get several results showing that this has been preinstalled on most Samsung devices since at least 2012. It can be safely Frozen or Disabled, if those are options.
This could also lead into the fact that unless you installing software from Unknown Sources (you had to turn on the ability manually), you likely do not need any antivirus or security app on your device and it will cause more of a hindrance than do any good.
