警惕！我国境内捕获“银狐”木马病毒变种 2025年04月25日 12:05　来源：中国新闻网
--just read the news and tried to verify whether my notebook got 木马病毒变种, due to file explorer got [windows ssd c showing yellow error logo !] so followed [How to Turn On BitLocker] then Right-click on the C drive and select [Turn on BitLocker] which didnt show the function. so clicked Network which very weird showed [car-f20b]

when i Google searched [car-f20b] which related to Honda F20B engine; This engine series was used in the 1997-2001 CF4, CF5, CF9, CL3 Honda Accord and Honda Torneo from Japan.
--what the hell ghost hide in my notebook file explorer network for? when i tried to click it the [car-f20b] auto disappeared. the other 3 didnt which included Roku, Gateway, router. unknown ghost [car-f20b] control my notebook?

here is what i searched [why car-f20b showed in file explorer network in win11?] and got:
The name "car-f20b" appearing in File Explorers Network section in Windows 11 likely indicates a network device or a computer connected to your network that has been assigned that name. This could be a personal computer, a server, or another device that supports network sharing.

Here is a more detailed breakdown:
Network Device:
Its possible that "car-f20b" is the assigned name of a device on your network, such as a router, printer, or another computer.
Computer:
If "car-f20b" is a computer, it means another user on your network has configured their computer to share files and folders, making it visible in File Explorer.
Network Discovery:
Windows 11 uses Network Discovery to automatically find and display devices on the same network. To see devices, you need to ensure Network Discovery is enabled in your network settings.
Workgroup:
If your network uses a workgroup, all devices must be configured to be in the same workgroup for them to be visible in File Explorer.

--so i tried to verify the other 3 [ie Roku, Gateway, router] but shocked me the Gateway auto disappeared too, what is going on? i also did MS scan so far showed [No threats found] , it finished then showed Threats found : Adware:win32/webcake 4/25/2025 2:58am (active) High
so i clicked [Start actions] *** need to save 1st will continue write
in the end showed:
No current threats.
Last scan 4/25/2025 2:21am (customer scan)
5 threats found scan lasted 37min 21 sec. 929855 files scanned

however didnt show what are the 5 threats found. decided to run [MS Defender antivirus (offline scan)] which requested to save all files before take action and i did but didnt see it execute, tried 3 times then gave up but run [full scan]. which showed :
No current threats.
Last scan 4/25/2025 3:10am (full scan) 4 threats found
-- i did refresh browser not sure whether related and reduced 5 to 4.
scan lasted 39min 5 sec. 944173 files scanned

Cant see it can catch Network ghost [car-f20b] at all. i would say it is MS one of back door to steal user data files or else (money ?).

--5 threats detected by MS defender but only shows one of 5 threats ie Adware:win32/webcake
-------------------------------
from 4:25am-5:17am i did as: Quick Scan, Full Scan, Customer scan by each subfolder to find out which sub-sub-directory got threats, and MS Scan (offline) which still not work. finally found weird things as : FeedbackHub, FlashIntegro, FreemakeVideoConverter, Freemake, Public Documents are all empty unknown folders so deleted. then found A(folder) can see 2 tax related files but the scan showed 6files, B(folder, tax app related) cant see any files but scan showed 44 files. so i immediately restore those deleted "empty folders" in case some files hided.

the puzzle is all Quick Scan, Full Scan, Customer scan showed 0 threats that seemed Adware:win32/webcake auto disappeared. so i did the final full scan (after restored) . i am not shocked all tax-related folders cant see because tax app company did in 2025 that before 2021 all deleted as wont support PDF files excuses. All usa companies related to us can auto change our download data files (bill statements, banks statements and tax-related files) plus MS with file explorer auto deleted many my data files which including FRAUD folder and others. suspect wipped off all evidence related stolen data files that my hard working on data leak, caught bank money stolen evidence, contact government fraud help ...related.

the full scan 5:12am 4 threats scan lasted 35min 58 sec 935143 files (after restored those deleted empty folders)
now going to scan those unknown folders by customer scan which still 0 threats so deleted them as 0 files. now scan the most possible big folder 70981 files again and main folder 408831 files, downloads 743 files, desktop 3807 files all are 0 threats again, but windows SSD(C:) 6:31am 37min 59 sec 922250 files 4 threats. cant caught or MS windows security(antimalware service executable) bug? verified windows SSD(C:) each subfolders, perflogs and unkown users defaultuser10000 wont allow. user(me) 7:26am 4 threats 24min 15sec 490826 files

ps The "defaultuser10000" folder in File Explorer isa temporary folder often created when theres an issue with a user profile, such as during an upgrade or patch, or when a user forgets their password and uses the recovery option. Its considered a bug, but generally harmless and can be deleted. ....Deletion: You can delete the folder without causing any harm

--what it is talking about user forget password? what password uses for, MS account ? definitely would delete it (the less unknown folders or bug the better) after verified which folder caused 4 threats.

Considering scan Network then found [Roku already disappeared, Gateway, router] Gateway disappeared too, only router now. what kind of back door can disable our equips connected to network and added unknown Japan ghost [car-f20b] to our network ?

4/26/2025 Scare me to the death when tried to test admin account settings got errors as :

This device is blocked by Access Control in the router.
--so verified spouse notebook connection which lucky me he didnt get error, it caused by I forgot 2 secret questions answers. in the meanwhile also changed admin password failed at least 7 times so gave up. fortunately the company accepted the new password. i also followed the more secure suggestions so changed IP address into auto assigned. but forgot it blocked myself out because security didnt recognize the new IP address. the good thing spouse didnt change to auto so use his notebook to mark as allowed my new IP address.
And also added Device Name :RalinkLinuxClient, MAC address: c8:02:10:62:20:07 as blocked device. i hope router company can allow Device Name : car-f20b (without MAC address) as blocked device. it is not easy wrote down hacker device MAC address in time.
