Virus flashdisk gampang dihapus

Prinsip Kerja
Cara kerja virus lokal umumnya mengandalkan penyebaran via flash drive, yaitu:
1. memanfaatkan fasilas windows yang menjalankan file autorun.inf saat sebuah removable-drive dimasukkan
2. memalsukan ikon folder, sehingga orang awam terjebak untuk mengklik ikon folder (yang namanya persis dibuat sama dengan folder tsb).

Berdasarkan kedua cara paling umum itu, maka ada langkah pencegahannya yang saya akan coba bahas dalam bahasa sudo code

Berikut Pseudo-code-nya
Load API-related-to-shell

Class TrapARomovableDevice {
Detect if a removable device is inserted,
return y,n

Detect if a removable device is a flashdrive,
return y,n

if both returns equal y, then
run Class CheckAutoRun

else exit
}

Class CheckAutorun {

Get DriveValue as dv

attrib -s -h -r -a %dv%:/autorun.inf

Detect if %dv%:/autorun.inf exist? return y,n

if return equals y, then
move autorun.inf to autorun.txt

else exit
}

Class CheckFakeFolder {

Get DriveValue as dv

attrib -s -h -r -a %dv%:/*.*

Put in array as FolderName

While each arrray(FolderName).exe exist
Do del arrray(FolderName).exe

While each arrray(FolderName).com exist
Do del arrray(FolderName).com

While each arrray(FolderName).scr exist
Do del arrray(FolderName).scr

While each arrray(FolderName).pif exist
Do del arrray(FolderName).pif
}

Pengen coba?
Untungnya udah ada orang yang berbaik hati bikin programnya disini:
iKill 1.2

Ada juga blogger Indonesia yang buat file bat-nya, cuman harus diganti manual nama drivenya setiap saat setelah memasukkan flashdisk. Sayangnya saya lupa baca ditautan mana...

Bermula dari jebolnya komputer pribadi yang digunakan untuk layanan e-learning dan repositori abstrak skripsi bagi institusi tempat kami mengabdi, petualangan menyambung nyawa komputer tua dimulai. Spike  listrik adalah biang utama rusaknya perangkat ini. Ya, sebaiknya perangkat elektronik perlu pelindung dari lonjakan listrik sekedipan mata yang mematikan. Komponen yang menjadi almarhum akibat spike  kali ini adalah VGA card dan tombol reset (kok bisa, ya?).  VGA card Radeon X1300 128 MB Komputer ini sudah cukup tua usianya, sekitar 9 tahun. Motherboard-nya Intel DG31PR dengan prosesor Intel Core 2 Duo E7500 , memori DDR 2 3 GB dan harddisk SATA 500 GB 7200 RPM.  Sistem operasi yang digunakan adalah Slackware Linux  versi 13.37. Kinerja komputer ini sebagai server e-learning untuk kategori dosen jelata macam kami sudah cukup memuaskan. Sekitar 80 orang pengguna dapat dilayani secara simultan, walau bottleneck -nya tentu saja di hard-disk dan wifi seputar ruang lab.

Writing and reading float using Arduino EEPROM

This post is just for a personal reminder after reading discussions from elsewhere about storing and reading float values to/from EEPROM with Arduino. Scenario Writing negative float to EEPROM can be tricky, since EEPROM only recognises up to 8-bit values (see Tronixstuff  explanation ), therefore it requires an additional algorithm to make it able to store negative and float.  the scheme is to use four bits of the ATmega328's EEPROM to store numerical parts of a float value. The function involved is union . //union  value typedef union{   float flt;   byte array[4]; } FloatConverter; The code You may grab the code here

LM35 Incubator with LCD 16x2 on Arduino

Past articles: NTC thermistor incubator (part 1): connecting triple thermistor NTC thermistor incubator (part 2): multi-buttons input for single Analog pin   Introducing CodeBender Today I found a great code sharing website called codebender  that allows me to use Arduino in any computer since it has online IDE with crossplatform browser plugin to upload to Arduino system. Remember, Arduino is an Open Source Hardware project, I encourage people to share as much as we learn from others too. Sharing knowledge is awesome! Since everything is online and pretty straight forward, I will try to explain my project as simple as possible. The Aim My aim is still to produce an incubator, but today the specification will be: Internal LM35 temperature sensor that will be placed inside the incubator External LM35 temperature sensor that will monitor ambient/room temperature Peltier element that will be connected through a relay module Displaying internal (current temp, CT), e
