Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.

Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

EtreCheck is a FREE simple little diagnostic tool to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac. It will not display any personal info.

Pastebin is a good place to paste the whole report if you capture the URL while there…

https://pastebin.com/

Whew, they've changed pastebin & made it harder, but after pasting in, click Create new paste button, then Embed button, then copy the URL...

The important part of the above is between the quote marks...

If pastebin is a problem for you then workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck. In a Reply before you click post, look for this to add longer texts...

Oh, that’s nasty.

The bank gets users to install (busted?) Diebold code—what amounts to installing malware—as “security”?

Reminiscent of the Sony rootkit scandal.

Also fodder for some added EtreCheck flagging by etresoft.

Yes indeed. :(

Could be same.

Might uninstall SyncMate.app, many crashes related to that.

Great to hear, good work my friend, I'd agree with Mr Hoffman.

Get your backups going. Preserving your data is the priority here, and should be happening again before making any changes.

Remove Avast.

Remove AppCleaner.

Remove Java, unless you need that.

Consider removing the Google apps, as those apps been known to get very busy in the background,

The Apple MRT malware removal tool has been active, whether that’s due to malware, or colliding with another installed app is unclear.

I’d leave Java off, unless some other app you use starts grumbling about not having that installed. If something else you need uses it, reload it. Otherwise, leave it off. One less app to maintain.

As for re-loading Avast, I wouldn’t add anti-malware. Use the existing Apple (Gatekeeper/XProtect/MRT) anti-malware. While Avast has had some… surprises in the past, I’d expect they were not the only anti-malware or add-on VPN vendor involved in those activities.
