    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 )
