macOS irritating loading circle in login screen

It's merely one of a thousand different adware variants, all of which are easily removed, and for which no additional product is required to remove it.

As a "pcvark" variant it's not even anything new. Adware is something a Mac user willfully installs, by intentionally disregarding the warnings macOS provides and ignoring the "terms and conditions" that accompany its installer.

"Shlayer" typically masquerades as a phony Adobe Flash Player "update": Beware bogus Adobe Flash "installers" - Apple Community. Adobe Flash Player has been discontinued. No one should be using it any more, on any platform.

I have yet to encounter a single adware variant that does not do exactly what those Terms and Conditions say it's going to do. In other words if a user is bound and determined to do so, nothing will stand in the way of them installing junk.

And on that note, "Kaspersky" is junk. Uninstall it in strict accordance with its instructions. Never install it, or anything like it, ever again.

Is being a Mac virus tester a steady job?

If you are "testing viruses" why do you worry about getting one?

Anyhoo, as there are no "Mac viruses" you can safely remove Kaspersky and reinstate all three built in Protections, and then test performance again. If you want to put it back in your quest for viruses, that is up to you, but if it is causing the slow login you'll just have to live with it.

You dont need Flashplayer these days and being a malware tester you know that recent Flashplayer updates contain malware payloads

The only malware tool we recommend is free version Malwarebytes for a single removal run then uninstall.

I assume/hope the public beta tool you installed recently does not mean there is any beta material still installed.

I'm a virus tester and I'm afraid that I get a virus on my Mac…

That's equivalent to being an alligator hunter at the North Pole. There are no Mac viruses. None. Nada. Zip. Viruses are malware that self replicate. These do not exist and haven't since the release of OS X, 10.0. You're wasting your time looking for unicorns. There are plenty of Trojans, which is malware the user needs to be tricked into installing in some manner. It can't get on your computer by itself.

Get rid of Kaspersky. It is doing nothing useful - at all. It has no viruses to look for, and there is no AV software of any kind that will even attempt to stop you from installing a Trojan. Only very rarely will they even tell you you've installed any. I've seen EtreCheck reports here more than once where the user had as many as four different AV titles installed and running at the same time, and their Mac was still full of crap.

You only have 8 GB of RAM installed. That's not much, especially when you have not just one, but two VM software packages installed. At least one of which appears to be loading at startup (VMware). Your Mac is starving for RAM, which causes it to swap out data to disk as virtual RAM.

Get rid of Teamview. Never, ever have remote access software installed without having a very good reason for it being there.

Install Etrecheck from App Store and attach the report using the Additional Text icon

Obviously you haven't any Antivirus or cleaner/booster apps installed?

Get rid of it!!!!!

Like its ilk, it can cause exactly those symptoms
