Can anyone help me identify new software named Mozillod5.2f5?

That name screams “fake Mozilla-ish bundle” to me, not a real product. I slightly disagree with @techchizkid on one part though: being in Program Files does not make it safe. Plenty of junk installers drop stuff there just to look legit.

A couple other checks I’d do:

  • Look in Apps & Features and sort by install date. See what arrived the same day.
  • Check Control Panel > Programs for a publisher name and uninstall option.
  • Upload the main .exe to VirusTotal. One scan result alone is meh, but 20+ engines agreeing is a clue.
  • Open Event Viewer or Reliability Monitor and see when it first appeared or crashed.
  • Check your browser extensions too. Weirdly named apps are often adware sidecars.

If you don’t recognize it, and it has no clear publisher/site, I’d remove it after scanning. Also create a restore point first, just in case. The name looks sus as heck, honestly.
