How Linux Mint, NTFSFix, and ClamAV Saved Microsoft Publisher – The Future is Open donwatkins.info/2025/12/17/how

How Linux Mint, NTFSFix, and ClamAV Saved Microsoft Publisher

Recently, I was helping a Windows-using friend transition from her ten-year-old Windows 10 laptop to a new Windows 11 laptop. All of her important files had been backed up by Microsoft OneDrive, which was a great relief when we logged into the new computer. My friend is a Microsoft Publisher user, and you guessed it: Microsoft has announced the end of life for Publisher in October 2026. Since she’s an Office 365 user, she has until then to export all her Microsoft Publisher files as PDFs or lose the information.

The ten-year-old laptop had become unusable, locked up mid-application with Windows errors, and refused to budge. It was an i3 with 4 gigabytes of RAM that started as a Windows 8 laptop and was upgraded to Windows 10 about five years ago. It had seen better days, but I suggested to my friend that I might be able to resurrect it so she could continue using it with the 2021 version of Microsoft Publisher, which will no longer receive updates. She said, “Sure, I’m happy to have you work your magic!”

I took it home and did a live boot with Linux Mint MATE 22.2, but the Windows drive would not mount. It gave me an error message:

$ wrong fs type, bad option, bad superblock on /dev/sda6

I ran fsck on the drive and got more messages indicating that a bad block existed and needed to be repaired. How could I fix the error from within this live boot environment? That’s when I happened upon ntfsfix. The program was already loaded in the live boot environment. I used lsblk to determine the exact location of the NTFS disk in the disk system and issued the following command:

$ sudo ntfsfix -b -d /dev/sda6

There are several options for the command:

ntfsfix v2022.10.3 (libntfs-3g)

Usage: ntfsfix [options] device
    Attempt to fix an NTFS partition.

    -b, --clear-bad-sectors Clear the bad sector list
    -d, --clear-dirty       Clear the volume dirty flag
    -h, --help              Display this help
    -n, --no-action         Do not write anything
    -V, --version           Display version information

In my case, I used the -b (clear-bad-sectors) and -d (clear-dirty). That command fixed the problem I had with the NTFS partition, and I was now able to download and install Clam Antivirus to clean up the suspected malware causing the issue.

$ sudo apt install clamav

Then I was ready to scan the disk for viruses and malware. I opened a terminal in the mounted Windows drive and entered the following command:

$ sudo clamscan -irv --remove 

Those clamscan options: – only prints files that are infected, r-scans directories recursively, and v- provides detailed output during the scan. The –remove option deletes any files that are found to be infected. Be careful with that last option.

The laptop has an i3 CPU and 4 GB RAM, and the process for scanning a 400-gigabyte drive was lengthy. It took overnight to complete the scan, but when I started the laptop in the morning, I was able to log in without difficulty, and my friend is delighted at the prospect of extending the life of her access to Microsoft Publisher.

In the end, what began as a seemingly hopeless situation with a locked-up Windows 10 laptop turned into a valuable lesson in resourcefulness. By combining the flexibility of a Linux live boot, the repair power of ntfsfix, and the thoroughness of ClamAV, I was able to breathe new life into aging hardware and preserve access to software that is nearing its end of support. For my friend, this means more time to safely transition her Publisher files, and for me, it’s a reminder that with the right tools and a bit of persistence, even a decade-old machine can still serve a meaningful purpose.

Ogni tanto qualcuno mi chiede: “Ma sul server non metti #clamav? ... sul server?

No. E no, non sono impazzito 😅

L’idea di fondo è semplice: sull’80% dei server Linux ClamAV è poco più che un placebo tecnico.

ClamAV nasce per:

– fare da filtro antivirus su mail server e gateway
– trovare soprattutto malware per Windows
– lavorare in modo reattivo: firma nuova → aggiornamento → scansione

Su un server “normale”, che non fa da file-server per PC Windows e non consegna mail a client insicuri, ClamAV finisce per:

– macinare CPU e I/O a caso
– scansionare binari di sistema installati dai repo ufficiali
– dare un’illusione di sicurezza (“tanto c’è l’antivirus…”)

Il punto è che i problemi veri su un server non sono i virus anni ’90 nei file, ma:
– servizi esposti male (SSH aperto ovunque, pannelli admin ovunque)
– software non aggiornato
– webapp buggate
– permessi e ruoli messi a caso
– password riutilizzate o troppo deboli
– niente log, niente monitoraggio, niente backup

Se devo scegliere dove mettere tempo e risorse, preferisco di gran lunga:

– aggiornare regolarmente il sistema
– avere backup testati e fuori dal server
– configurare bene firewall e reverse proxy
– usare chiavi SSH invece delle password
– limitare i servizi solo a ciò che serve davvero
– tenere d’occhio i log con strumenti seri

ClamAV ha senso solo in casi specifici, tipo:

– mail server che filtra allegati per utenti Windows
– file server dove i client scaricano roba e voglio mettere una barriera in più

Su tutto il resto, il “mettere l’antivirus sul server Linux” è più un’abitudine mentale che una reale misura di sicurezza.

Morale:

meno placebo, più buone pratiche. I server ringraziano, anche le CPU 😉

Запустила тут ClamWin, отправила обновляться, а он мне – 403 и кулдаун до завтра. Кулдаун, разумеется, снимается удалением файла freshclam.dat, но сама причина... Открываю ссылку с файлом обновления из лога в броузере, и получаю капчу клаудфлары. Гениальное, конечно, решение для автоматизированных обновлений. При чём, оно не пускает ни с проксей всяких, ни с белого айпишника. Почувствуй, так сказать, дух свободы. #программы #clamAV

sudah lama sekali tidak pakai #ClamAV, dulu pas masih pakai Linux (sekitar tahun 2009/10) ane pakai ClamAV1 untuk bantu hadang virus meski tahu virus - virus flashdisk itu tidak akan berimbas ke Linux.

tapi keingin tahuan tetap saja menang dan membuat ane memasang ClamAV di distro ArchLinux2.

ane colok USB Flashdisk kosong ke PC di warnet, otomatis langsung keisi dengan banyak sekali folder aneh dan ajaib dengan nama huruf, angka, dan karakter acak. Tersenyum puas, ane bawa balik ke rumah. Tak perlu dikawal voojrider karena virus ini tidak bikin harga saham Kimia Farma3 meroket.

sesampai di rumah ane colok ke notebook dan memang tidak terjadi apa - apa. Ane scan dengan ClamAV juga tidak ditemukan apa - apa, "Flashdisknya sehat wal afiat kak" begitu kesimpulan ClamAV.

tak puas, ane pasang Windows guest di (Oracle)4 Virtual Box, kemudian install #SmadAV antivirus buatan anak SMA. Atur supaya VirtualBox bisa baca USB Flashdisk dan lah dalah budal neng sawah SmadAV5 langsung deteksi virus dan memulai penghapusan.

sejak saat itu ane lebih percaya SmadAV daripada ClamAV (untuk urusan hajar virus lokal) dan bertekat suatu saat akan beli lisensi berbayar SmadAV6.
