Trend Micro Predictive Machine Learning detects and blocks malware at the first sign of its existence, before it executes on your system. When enabled, your Trend Micro product detects this malware under the following machine learning name:

    •  Downloader.VBA.TRX.XXVBAF01FF048

Step 2

Before doing any scans, Windows 7, Windows 8, Windows 8.1, and Windows 10 users must disable System Restore to allow full scanning of their computers.

Step 3

Scan your computer with your Trend Micro product to delete files detected as PUA.W97M.PhishTest.KBF.
