malwarebytes = Advanced Mac Cleaner
Howdy,
I found Advanced Mac Cleaner (from inside an Adobe Flash update--Steve J. hated it) had insinuated itself into the Process start. Using Activity Monitor I could not kill, abort etc the helperamc (note the misspell) PID, it came back after maybe 2-3 seconds.
I found Malwarebytes recommended on Apple.com.
Now Malwarebytes wants money....so did Advanced Mac Cleaner...so they are the same?
