Question malware detected other software

[carlos88]

I ran a full scan with Microsoft Defender on my PC and it found the file AppData\Roaming\secure\QtWebKit4.dll (Trojan:Win32/Wacatac.C!ml).

But before using Defender, I had run a full scan with Malwarebytes Free and Kaspersky Free and found nothing. Why did it detect this now?

Is this type of malware the kind that modifies, deletes, or corrupts files on the PC?

You've created too many threads on forums, don't you think? One, two, three, four, and plus one here. 🙂

Is this your file? If yes - upload this file via the link, wait for the analysis to be completed, and attach the link to the TIP's analysis here.

@carlos88 As I see, you didn't upload the file into TIP (no dynamic analysis and button "submit to reanalyze"). But now it is being detected by Kaspersky. Any other questions?
