On the surface, there are many superficial similarities вЂ“ file naming conventions, similarity of icons, references to PCVARK on the Mac File Opener website, etc. Advanced Mac Cleaner, and other PCVARK products, are code signed with a certificate belonging to вЂњPCVARK software Private Limited,вЂќ while the Mac File Opener certificate belongs to вЂњTechyutils Software Private Limited.вЂќSince this may lead to the question of whether Techyutils and PCVARK are actually related, or if Techyutils hijacked an Advanced Mac Cleaner installer for their own purposes, I began to do a little research.

Examining the application code of Mac Optimizer (from Techyutils) and Advanced Mac Cleaner (from PCVARK) side-by-side shows that they are nearly identical for the most part.Thus, two supposedly different apps, from supposedly different companies, both share the same code (and nearly identical user interfaces). But then I realized that I have a copy of a different PUP, also signed by the same Techyutils certificate, called Mac Optimizer.
