hundreds of files being written to bin

BucksRothers provided this solution that has worked for others:

• Turn off you wifi, then quit the OneDrive app.
• Navigate to the application folder and control click the OneDrive app.
• Click Show Package Contents
• Open the Resources Folder
• Click ResetOneDriveAppStandalone.command
• Open OneDrive and sign back into your account.

Other users have experienced the exact same behavior with the Office 365 subscription along with the OneDrive synchronization of files. I have not seen the specific solution to stop this from happening, but it is the combo of the Office virtualization syncing these files with OneDrive to your trash. Reviewing the Microsoft support pages may offer a solution and if I find one, I will post back.

Thanks. That's cured it. As a temporary measure I disabled OneDrive in the Log In items system settings so it didn't run. All back to normal now.

Good Job! Sorry it took so long to find the solution for you.

Sounds like you have Microsoft OneDrive installed? If that is the case, then you will need to check online at your account and make sure the Recycle Bin is also empty on OneDrive. If you have OneDrive installed and don't need it, then uninstall it and your problem will most likely go away.

Tat could suggest adware. Often adware files will use that sort of scrambled file naming to make it hard to block or even search for them. Have you used download hosting sites† or torrent downloading? They are big players in distributing adware.

Most of the AV stuff is, in addition to being useless on Macs, cannot handle adware. The only third-party adware detection/removal tool most of the senior folks here mention is MalwareBytes. Its developer was a respected and long-serving contributor here. The demo version runs manually; the pay-for version intercepts incoming adware in ral time.

Do avoid more aware, PLEASE get ti only from the developers site: https://www.malwarebytes.com/mac
