Windows 10 Defender

Post by jstevens »

I just noticed that Windows Defender started to flag a file as having a virus. Is it possible to determine what in the vbaProject.bin may be causing the system to flag it? The current build is 19042.867 which was updated today.

file: \\USB_Drive\Shared Folders\Documents\myFile.xlsm->xl/vbaProject.bin

Detected: TrojanDownloader:O97M/LolBinAbuse!ibt
Status: Quarantined
Quarantined files are in a restricted area where they can’t harm your device.
They will be removed automatically.


Your thoughts are appreciated.
Regards,
John

My first guess would be that it is a false positive.
Does the workbook contain userforms?

If you want another opinion submit the file to VirusTotal.

Hans,

The workbook does not contain user forms and I would have to agree with you about the false positive.

I restored a backup from the prior day and have not encountered the false positive.

Previously, Windows Defender prevented me from living, constant pop-ups and constant program locks, I just needed to reinstall Windows 10.
