'Software Update' app - malware or false positive?

[technicallychallenged]

Hi everyone. I was wondering if anyone could help me as I'm not very technically minded and I'm not having much success finding help with this issue I have.

I've been experiencing problems with random ads popping up on my phone (a Kazam Tornado 348) every so often, so I downloaded Malwarebytes. The full scan flagged up one app detected as malware (PUP.Adware.Gmobi), but attempts to uninstall this app have been unsuccessful. I even went to the last resort of factory resetting my phone, and the app is still present. I'd read something about cheaper phones coming with adware-type apps pre-installed, but wasn't sure as to the legitimacy of this claim.

When I looked at the app info under Settings, it shows up as a 'Software Update' app with a blue icon with a white upwards-pointing arrow on it (see attached images). The package 'com.rock.gota' is meaningless to me, and Googling it seems to bring up mixed results of its significance. The thing that concerns me most is the permissions of this app, as the only permission has is 'read sensitive log data'. I can't do anything to change this permission, and I'm concerned my security may be being compromised.

I rang my phone service provider (Virgin Media), who said they weren't sure what to do, but suggested I update Google Play Store? Which doesn't seem to have done anything to help. Since taking the screenshots below, I've cleared the cache/data and forced stopped the app, but it seems to sporadically restart itself.

I just want to know whether this is normal and Malwarebytes giving me a false positive, or if not, if there's anything I can do about this that doesn't involve invalidating my warranty (e.g. rooting)?

Any pointers in the right direction would be most appreciated.

Edit: I should probably add that my antivirus (AVG) and other malware scanners I downloaded to try and remove this app did not detect this particular app as being problematic. Not sure how significant this is...
