When I click on the 'Move to bin' option, the message just disappears and reappears in a few seconds... and the malware does not get moved to the bin.

It does get moved to the bin, but a launch agent just respawns another copy of it, so there is no effective result of that action. The launch agents / launch daemons responsible for its reappearance need to be removed also.

You do not need to download or install else anything to get rid of it. They are known by various names but they travel in similar circles. To guarantee its complete eradication proceed as below. After that, there will be a few additional steps to complete.

Eradicating them is simple. You already did the most challenging part, which was to capture and post a screenshot.

Navigate to the following folder, and post its contents in a screenshot:

~/Library/LaunchAgents

To open that folder, copy the entire line above and paste it in the Finder's Go menu > Go to Folder... field. Make it look like this:

... and click the Go button.

A Finder window will open. Take a screenshot showing all that folder's contents, and post it in a reply. To learn how to do that please read the Appendix in the following User Tip: Writing an effective Apple Support Communities question.

Usually, there is nothing in that folder so don't be surprised to find it empty. The reason for starting with that folder is to eliminate other potential causes before proceeding with steps that will identify and eradicate whatever is affecting that Mac.

There will be additional instructions to follow and this is just the first step.
