Adware is probably why the "other process" flag was triggered.
Other than that, your report looks OK except for one thing that concerns me. Your SanDisk SSD performance:
Performance:
System Load: 1.96 (1 min ago) 2.09 (5 min ago) 2.14 (15 min ago)
Nominal I/O speed: 4.76 MB/s
File system: 31.98 seconds
Write speed: 141 MB/s <<<-----
Read speed: 529 MB/s
I have a similar MacBook Pro with an OWC SSD and it scores in the same test are:
Performance:
System Load: 1.61 (1 min ago) 1.60 (5 min ago) 2.94 (15 min ago)
Nominal I/O speed: 0.15 MB/s
File system: 28.20 seconds
Write speed: 487 MB/s <<<-----
Read speed: 482 MB/s
Your write scores are roughly the same speed as some mechanical hard drives. You may need to check with SanDisk support because I believe something is seriously wrong in that discrepancy between read and write speeds. Most of us use eitehr Crucial or OWC solid state drives for this upgrade,
