- Virus pada dasarnya hanyalah sebuah program atau skrip pemrograman seperti halnya program-program yang sering kita temukan: Ms Word, Excel, dan lain-lain
- Virus berukuran sangat kecil sehingga bisa untuk dimasukkan kedalam flashdisk atau alat penyimpana lainya dan biasanya icon berbentuk sama seperti folder atau dokumen lainya
- Biasanya virus-virus ini menyamar dengan menggunakan nama file yang ada dalam flashdisk atau disket anda, sedangkan dokumen asli anda disembunyikan dalam hidden file.
- Saat anda klik dua kali virus ini maka program virus akan di eksekusi. Langkah pertama yang dilakukan virus adalah membuka dokumen yang disembunyikan untuk mengurangi kecurigaan pengguna.
- Berikutnya virus akan mengcopy dirinya ke hard drive dan menuliskan registry di HKEY_LOCAL_MACHINE\Software\Microsoft \Windows\CurrentVersion\Run atau di HKEY_CURRENT_USER\Software\Microsoft \Windows\CurrentVersion\Run agar program virus secara otomatis di eksekusi saat komputer pertama kali menyala.
- Jika perlu Virus mendisable Task manager dan regedit untuk mencegah pengguna menghapus virus secara manual
- Berikutnya virus akan aktif untuk memeriksa jika ada file dokumen baru dalam flashdisk atau disket dalam setiap beberapa detik, yang kemudian akan disembunyikan kemudian mengcopy file virus dan memberi nama sesuai dengan nama file yang disembunyikan tadi. Virus juga akan menuliskan script Autorun.inf dalam flashdisk secara hidden agar virus secara otomatis dijalankan saat flashdisk di klik dua kali dalam My Computer
CARA KERJA VIRUS
SISTEM OPERASI PADA KOMPUTER
Sistem operasi adalah perangkat lunak yang dibuat untuk mengendalikan dan mengkoordinasi seluruh sistem komputer. Dengan adanya sistem operasi maka sistem komputer dapat menerima masukan berupa instruksi dari keyboard,mencetak hasil,membaca dan menyimpan data dari dan ke media penyimpanan,mengatur komunikasi antar komputer dan juga mengatur hubungan degan perangkat lunak aplikasi.
ada dua peranan sistem operasi sebagai resorce manager dan sebagai extended machine. sebagai resorce manager sistem operasi menjamin kelancaran dan kemudahan pemakai dalam mengoperasikan kompute. sebagai extended machine sistem operasi menyembunyikan perangkat keras yang rumit dan berlevel rendah menjadi lebih sederhana bagi pemakai.
windows xp merupakan salah satu sistem operasi yang banyak digunakan pemakai saat ini. sistem operasi ini sangat praktis dibanding sistem operasi yang lainya.Obyek dalam windows xp dapat berupa file,direktori,program,dokumen,disk dan lain-lain.
MENAMBAH RAM DENGAN FLASDISK
Cara menambah RAM dengan flasdisk yaitu dengan memakai software yaitu eBoostr. software ini sangat mudah sekali digunakan. gak usah pake lama langsung aja download eBoostr. kalau sudah dapet langsung instal aja di laptop km..
Jika anda ingin menggunakan flashdisk anda sebagai RAM maka beri tanda pada option "Use this Device",kemudian tentukan berapa besarnya yang akan digunakan sebagai penambah RAM.
Flashdisk yang Anda harus gunakan minimal USB 2.0, karena device yang digunakan harus mempunyai kecepatan hingga 3,5 MB/s. Flashdisk yang di gunakan untuk RAM, minimum 1,5x dari RAM yang terpasang. Misalkan RAM komputer Anda 1 GB, maka agar hasilnya terlihat, minimum flashdisk sebesar 1,5 GB. Ini juga berlaku bagi flashdisk tertentu yang mempunyai data transfer yang cepat, jika terlalu lambat flashdisk tersebut tidak bisa digunakan untuk Windows ReadyBoost.
wes gek di jajal wae.. tinggal klak klik klak klik aja kok....
