Cara merubah Urutan booting di Grub Linux

Saya memiliki 2 system operasi yaitu WIndows 8 dan Linux pepermint 6 dan ketika booting default booting yang terinstall oleh grub linux adalah pilihan pertama di linux pepermint, nah karena rasanya lebih mudah dan familiar menggunakan windows 8, maka saya ingin merubah urutan booting grub supaya windows 8 ada di urutan pertama sebagai default. Caranya adalah sebagai berikut :

1. Buka terminal window di menu
2. Ketik "  gksudo gedit /boot/grub/grub.cfg "
3. Setelah terbuka file grub.cfg kemudian cari kata "Windows " untuk menemukan entry booting windows.
4. Blok command menu list windows ini :

### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'Windows Boot Manager (on /dev/sda2)' --class windows --class os $menuentry_id_option 'osprober-efi-BC35-627D' {
insmod part_gpt
insmod fat
set root='hd0,gpt2'
if [ x$feature_platform_search_hint = xy ]; then
 search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt2 --hint-efi=hd0,gpt2 --hint-baremetal=ahci0,gpt2  BC35-627D
else
 search --no-floppy --fs-uuid --set=root BC35-627D
fi
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
}
set timeout_style=menu
if [ "${timeout}" = 0 ]; then
  set timeout=10
fi
### END /etc/grub.d/30_os-prober ###

5. Cari command booting Linux

### BEGIN /etc/grub.d/10_linux ###
function gfxmode {
set gfxpayload="${1}"
if [ "${1}" = "keep" ]; then
set vt_handoff=vt.handoff=7
else
set vt_handoff=
fi
}
.
.
.
.
.

Sampai ketemu command :
### END /etc/grub.d/10_linux ###


6. Copy pastekan command booting windows diatas command list booting linux
7. Tutup dan simpan Grub.cfg
8. Jalankan command " sudo update-grub " untuk update grub.cfg
9. Restart Komputer/Laptop anda

Cara Menambahkan Shortcut Pada Startup Windows 8

Bila anda menginginkan untuk menambahkan shortcut di "startup" folder windows 8, untuk menjalankan aplikasi tertentu agar berjalan tiap kali windows 8 start, maka path atau alamat startup folder itu emang udah berubah dibandingkan windows sebelumnya dan bila anda mencoba menggunakan serach "Startup" maka anda tidak akan menemukannya.



Untuk itu anda bisa coba langkah dibawah ini untuk menemukan startup folder tersebut.

Solusi

1. Pertama anda harus menggunakan account Administrator kemudian Tekan tombol Win+R maka akan terbuka kotak pencarian.




2. Ketik %appdata% dan tekan Enter maka akan terbuka folder “C:\Users\AppData\Roaming”.




3. Tambahkan alamat “\Microsoft\Windows\Start Menu\Programs\Startup” dibelakang address yang terbuka, maka akan didapatlan full address sebagai berikut :

“C:\Users\user\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup”.






4. Bila anda ingin menambahkan shortcut maka klik kanan dan klik "Create Shortcut here"



5. Maka anda bisa menambahkan shortcut ke folder startup yang akan dijalankan tiap kali windows 8 start.



6. bila anda merasa cara ini agak repot dan anda menginginkan menambahkan shortcut dari aplikasi tertentu yang anda sudah buka alamatnya anda tinggal klik kanan aplikasi itu, kemudian klik sendto Desktop (Create shortcut), kemudian setelah di desktop tercreate shortcut aplikasi itu anda tinggal copy Paste kan ke folder StartUp diatas.

Virus Win32/Sality Remover

Pernahkah anda mengalami komputer/laptop kesayangan anda terinveksi virus yang menginveksi file file berextensi exe, pif dan Scr dan benar2 bandel karena susah untuk dibersihkan, tanda tanda nya adalah taskmanager disable, regedit disable, dan kita tidak bisa memunculkan file hidden di explorer karena tiap kalo kita klik folder option untuk show hidden file ketika klik OK/Apply ternyata tidak berfungsi?

Virus ini mengubah registry kita di alamat :

• HKEY_CURRENT_USER\ Software\ Microsoft\ Windows\ CurrentVersion\ Policies\ system
  DisableRegistryTools = 01, 00, 00, 00
  Menonaktivekan Windows Registry Editor.
• HKEY_CURRENT_USER\ Software\ Microsoft\ Windows\ CurrentVersion\ Policies\ system
  DisableTaskMgr = 01, 00, 00, 00
  Menonaktivekan Task Manager.

Kemudian mematikan warning display dari security center windows :

• HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Security Center
  UacDisableNotify = 01, 00, 00, 00
• HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Security Center\ Svc
  AntiVirusDisableNotify = 01, 00, 00, 00
• HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Security Center\ Svc
  AntiVirusOverride = 01, 00, 00, 00
• HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Security Center\ Svc
  FirewallDisableNotify = 01, 00, 00, 00
• HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Security Center\ Svc
  FirewallOverride = 01, 00, 00, 00
• HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Security Center\ Svc
  UacDisableNotify = 01, 00, 00, 00
• HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Security Center\ Svc
  UpdatesDisableNotify = 01, 00, 00, 00

Selain itu virus ini juga menuliskan registry untuk mengelabui firewall, kemudian mengcreate registry untuk menjalankan service di rootkit sebagai sality.am



Meskipun kita sudah menscan dengan bermacam anti virus selain sality killer, yang terdeteksi cuma file file yang terinfeksi saja tanpa mematikan aplikasi yang dijalankan oleh virus ini sehingga percuma saja, bahkan meski kita format drive instalasi windows dan meng clean install ulang windows kita, karena dia sudah tersebar di hardisk, maka windows baru itu juga akan terinveksi kembali.

Dari https://en.wikipedia.org/wiki/Sality
Sality is the classification for a family of malicious software (malware), which infects files on Microsoft Windows systems. Sality was first discovered in 2003 and has advanced over the years to become a dynamic, enduring and full-featured form of malicious code.

Sality is a family of polymorphic file infectors, which target Windows executable files with the extensions .EXE or .SCR.^[1] Sality utilizes polymorphic and entry-point obscuring (EPO) techniques to infect files using the following methods: not changing the entry point address of the host, and replacing the original host code at the entry point of the executable with a variable stub to redirect execution to the polymorphic viral code, which has been inserted in the last section of the host file;^[2][3] the stub decrypts and executes a secondary region, known as the loader; finally, the loader runs in a separate thread within the infected process to eventually load the Sality payload.^[2]

Sality infects files in the affected computer. Most variants use a DLL that is dropped once in each computer. The DLL file is written to disk in two forms, for example:

•  %SYSTEM%\wmdrtc32.dll
•  %SYSTEM%\wmdrtc32.dl_

The DLL file contains the bulk of the virus code. The file with the extension ".dl_" is the compressed copy. Recent variants of Sality, such as Virus:Win32-Sality.AM, do not drop the DLL, but instead load it entirely in memory without writing it to disk. This variant, along with others, also drops a
driver with a random file name in the folder %SYSTEM%\drivers. Other malware may also drop Sality in the computer. For example, a Sality variant detected as Virus:Win32-Sality.AU is dropped by Worm:Win32-Sality.AU.^[1] Some variants of Sality, may also include a rootkit by creating a device with the name Device\amsint32 or \DosDevices\amsint32.^[6]

File infection

Sality usually targets all files in drive C: that have .SCR or .EXE file extensions, beginning with the root folder. Infected files increase in size by a varying amount.
The virus also targets applications that run at each Windows start and frequently used applications, referenced by the following registry keys:

• HKCU\Software\Microsoft\Windows\ShellNoRoam\MUICache
• HKCU\Software\Microsoft\Windows\CurrentVersion\Run
• HKLM\Software\Microsoft\Windows\CurrentVersion\Run^[1]

Sality avoids infecting particular files, in order to remain hidden in the computer:

• Files protected by System File Checker (SFC)
• Files under the %SystemRoot% folder
• Executables of several antivirus/firewall products by ignoring files that contain certain substrings

Removable drives and network shares

Some variants of Sality can infect legitimate files, which are then moved to available removable drives and network shares by enumerating all network share folders and resources of the local computer and all files in drive C: (beginning with the root folder). It infects the files it finds by adding a new code section to the host and inserting its malicious code into the newly added section. If a legitimate file exists, the malware will copy the file to the Temporary Files folder and then infect the file. The resulting infected file is then moved to the root of all available removable drives and network shares as any of the following:

• \.pif
• \.exe
• \.cmd

The Sality variant also creates an "autorun.inf" file in the root of all these drives that points to the virus copy. When a drive is accessed from a computer supporting the AutoRun feature, the virus is then launched automatically.^[1] Some Sality variants may also drop a file with a .tmp file extension to the discovered network shares and resources as well as drop a .LNK file to run the dropped virus.

Solusi :

karena virus ini juga menginveksi bootloader, driver, aplikasi, root system windows dan lainya, maka diperlukan sality killer untuk membersihkan virus ini, jd bukan cuma sekedar anti virus.

Sality Killer bisa di download di SINI, juga bisa dicoba aplikasi dari AVG khusus untuk membunuh virus sality ini di SINI.

How to play Movies with subtitle on TV samsung LED series 4

So I have bought this real nice 24 inches LED TV: Samsung UA24H4053AR 24-inch Widescreen HD Ready LED TV. we bought those TV HD because we need 1 more TV since my parent in law curently living with us and it feels be better to have 1 more TV, beside i like to play my movie file on TV. 

Since it is a HD TV, I thought of watching high definition movie on it. My preferred way to watch movies is with sub-titles. In computer, it is very easy to watch a movie with subtitles, but it was “almost” not the same in TV. First time I tried watching the movies with subtitles on my LED TV, I failed miserably.

 
So here is what I learnt with my ordeal with subtitles on TV:

• Your TV should be advanced enough to read a subtitles. Mine is.
• Name the video file and the subtitle files exactly same. Just the extension should be different, nothing else. usually ext for subtittle is srt.
• Keep the subtitles file in the same folder as the video file.
• Video format of the files also matter. I found it to be working .mp4 and .avi, mkv, etc.
• Now to activate TVsubtitle to enable subtitle show in the movie, to do so you can see on picture shown below which show you the process on my Samsung TV with bahasa launguage
• Press Tools on remote TV  
•  
• Then choose "pengaturan text layar" 
•  
• Then change wich previously default set as "Mati/Off" to "Bahasa1/On" 
•  
• Then You can back to movie played and you can see substitle on the screen.
•  

 That's what i've done to show subtittle on movie played on my  Samsung LEd TV series 4. Try it and enjoy nice shown movie with subtitle.
