Windows 10: Download contained a malware, Windows Defender blocked

    Download contained a malware, Windows Defender blocked


    I downloaded a file, and Windows Defender immediately popped up, saying a severe malware was found and quarantined, I deleted it.
    But, at first I didn't notice that the download itself contained the malware, so I downloaded it again (Who knew it can discover a malware while downloading, and not after executing) - So I actually downloaded it like 2-3 times.
    Now I know that in Windows Defender quarantined history there are 2 downloads.
    Am I safe? Or I should do a clean install on my PC? (Ever since I bought an SSD it's really easy and fast to do a clean install )

    Hi @mibaup

    Windows Defender should have displayed the name of the malware infection can you post it for us.

    Lets check your computer for malware infections please follow below instructions.

    Make sure to scan your computer with one scanner at time.

    • Click Finish.
    • On the Dashboard, click the 'Check for Updates' button.
    • After the update completes, click the 'Scan Now' button.
    • A Threat Scan will begin. Please allow it to progress through the scanning process.
    • When the scan is complete, if there have been detections, click Quarantines Selected button to allow the program to clean what was detected.
    • In most cases, a restart will be required.
    • Wait for the prompt to restart the computer to appear, then click on Yes.


    How to get logs: (Export log to save as txt)

    • After the restart once you are back at your desktop, open Malwarebytes once more.
