    Avast detected malware, but other 8 scanners did not. Is it false positive, or something else?


    So almost a week ago, I downloaded NetBeans and send it to VirusTotal.com to find out, if everything looks as it should. When I imported the NetBeans installer, the Avast malware detection poped-up, and I did not know why. So I used Avast "Full virus scan" and after that Eset online scanner. They found nothing. NOTE: I now know, that it was probably a false positive due to a VirusTotal scan..However, when I turned on PC, and connected to it headphones to charged them, and leave the PC in "the login to desktop" screen, the malware was detected. The alert was more of wider rectangle, than regu

    database of malware producing false positives or false negatives

    Many months ago I communicated with Malwarebytes about a trojan that was detected by Defender that was not detected by Malwarebytes. They indicated that Microsoft Defender is likely a false positive and to wait weeks or months for Microsoft to update their
    database. To date the Defender continues to detect a trojan that is not detected by Malwarebytes.

    Defender does not detect any malware on quick scans. However on full scans it detects this trojan that is not detected by Malwarebytes.

    How does an end user determine whether one antivirus program is producing false positives or false negatives?

    Is this a false positive?

    Hi, I am Dave, I will help you with this.

    That is a false positive if only one AV on VirusTotal flagged that file, and your 4 safety scanner scans did not find any malware on your PC, then you have nothing to worry about and no further steps to perform.
