The "Copy" task failed unexpectedly

I'm using windows 10.

After updated VS 2017 to 15.8.1 i started getting error below:

The "Copy" task failed unexpectedly.

I've tryed to move project to another physical drive, but it wasn't helpful.

The projects may vary and error is not repeating every build. What may cause this error?

It was InfoWatch, corporate info safety system, anti-malware like product.
