Question Restarting, disk checking and repairing ?

[hakaru_eitara]

Hello,
After running a full MalwareBytes scan for around 30 hours, I restarted my system. This is the second time I’ve encountered a disk check and repair process during boot. I’ve attached the relevant images, including the drive's SMART data. Should I run the CHKDSK command ?

chkdsk C: /f /r

would be enough ?and for Drive C ?
Why I receive checking for all drives?

Do I need fsutil dirty command as well ?

thank you

Did MalwareBytes scan finish, any positive finds and fixes? It's possible that it found and fixed some malware in a critical spot.
If CHKDSK found any problems it would generate folders named Check.001, 002 etc.
You also need to (re)check disks health. If all checks out you can stop that autochecking

Hello and thanks for your response, yes first I ran quick scan , it found 8 threats(if it was threat) 2 of them were Drives/HOSTS (they are replaced) , 5 of them were about recent installed TotalAv I had installed , one of them was folder in Local \Temp\ a DLL(ISHASH.DLL) which I cant see there. All removed , In the next round after 30 hours just find 2-3 files that aren't very important however I quarantine them and I ll delete them as well.
Few weeks ago also I did full scan with bitdefender premium and nothing special found.


So I have to run CHKDSK ? On which drive ? While in the restart it checked and repaired all of them ?
What about fustil dirty ? Do I need?

Thank you

Why I receive checking for all drives?

I've experienced this a few times in the past when booting from different versions of Windows on the same physical drive. When the dirty bit was set, the system checked all my hard disks which took ages. We need to work out why your system is misbehaving.

I ran quick scan , it found 8 threats

I find Malwarebytes scans to be over-cautious with a tendency to automatically quarantine some of my wanted programs, including several apps from Nirsoft. They exhibit "malware like" characteristics and I'm forced to used Advanced Scan and set Detection to Warn User. I've already set Warn User as the default in Settings, but the normal scan ignores this setting and quarantines files regardless. Better safe than sorry eh?

If Malwarebytes detects anything, I check carefully before allowing it to quarantine or delete suspicious files. If I forget to modify Advanced Scan, the next time I try to run a Nirsoft utility, it's vanished.

running a full MalwareBytes scan for around 30 hours

If your system is (potentiaily) riddled with viruses, it would be quicker and safer to wipe the boot drive (or use a new drive) and install Windows plus all your programs from scratch. It shouldn't take more than 8 hours to reinstall everything, certainly not 30 hours.

I normally limit Malwarebytes scans to my C: drive. Scanning up to 20TB of data on other logical and physical drives is a waste of my time and unlikely to yield anything my AV software won't detect. Of course I could be wrong, so I keep multiple backups on other machines and tape.

You might be able to save time by restricting your scans to the Windows boot drive-only, in Advanced Scan. That way I'd expect your scans to take less than 6 hours, or faster if you have a modern multi-core CPU and an M.2 NVMe boot drive.

Also:

In any case is all important data backed up at least 2 x to locations away from the system and drive(s) in question?

Verify that the backups are both recoverable and readable.

Thanka for your complete response, sorry , what you mean by misbehaving...?

not 30 hours.

30 hours is unusual of rootkit and all features have been enabled ?

Windows boot drive-only

Yes , registry and bootloader files and system files usually located on C:
I ran on all drives and enabled all options
