    Windows Defender detects Trojan:Win32/Fuerboos.C!cl in Firefox cache


    Is this a false positive? Its detected it at least 3 times now spanning 4 days. Each time it alerts me, I tell it to delete it, then I clear the entire Firefox cache. run Ccleaner (non-infected version) and run Malwarebytes. Only WD is detecting it.

    Running Latest Firefox with Ublock Origin

    ESET online scanner = clean
    MBAM = clean
    TDSSKiller = clean
    AdwCleaner = clean
    Windows Defender = clean (after I tell it to remove the file.)
    Kaspersky Security Scan = Clean

    Hi vram.

    When you run MBAM are you using a custom scan to scan all files and drives?

    I can't seem to find that option in the newest version, but I did go directly to the DIR in question and initiate a manual scan with MBAM and it detected nothing.

    Also ran sfc /scannow to check for file corruption. All was good.

    I the newer MBAM, click on Scan, left hand column, then Custom Scan.

    Make sure Kaspersky is also doing full scan.

    Gotta wait for it to show up again. Hasn't returned since I manually deleted the Dir in question.

    The links that were seen on google indicated that it was a unique finding using windows defender.
    So all the other scans were clean.
    The issue is/are all of your bank accounts and passwords etc. with the uncertainty.
