MFresident.exe

I’ve been noticing this app working in the background. Some consider it malware; but, Avast isn’t flagging it. Should it?

Which app?
without more information it is not possible to give advice.
EDIT: ah, now see it’s in the title: MFresident.exe
What is the location (path) of that file?

MFResident.exe

MFResident.exe, classified as a Trojan virus, is often covertly installed with third-party software, like iMyFone. Despite appearing harmless, it exhibits concerning behaviors and is also linked to other hazardous dispout.exe and ghsetup.exe. Trojan viruses such as this can hijack system processes, degrade system performance, and potentially open backdoors for other malware to invade. In this instance, users noticed popups for additional tools post uninstallation of iMyFone, pointing to the malware’s persistence. The virus resists removal unless processes like LocalService.exe and MFResident.exe are killed, enabling the deletion of iMyFone’s remnants in the Program Files. This emphasizes the importance of cautious software installation, as programs may bundle harmful components like the Trojan in question. For protection, use reliable antivirus software and scrutinize software downloads for potential threats.
