1. ILOVEYOU VIRUS Malpal Jey Cey b.

2. dEFINITION ILOVEYOU was created by Onel De Guzman, a college student in Manila , Philippines, who was 24 years old at the time. De Guzman, who was poor and struggling to pay for Internet access at the time, created the computer worm intending to steal other users' passwords, which he could use to log in to their Internet accounts without needing to pay for the service. He justified his actions on his belief that Internet access is a human right, and that he was not actually stealing.

3. definition The ILOVEYOU virus is delivered as an email with the subject "ILOVEYOU" and an attachment that, when viewed, causes the message to be resent to everyone in the recipient's Microsoft Outlook contact book. Though more importantly, it causes all JPEG, MP3 and other files on all receivers' hard drives to be deleted. ILOVEYOU virus is actually a worm which replicates itself and spread from system to system without human interaction. The ILOVEYOU virus spreads through email. Once a person opens the attachment, the worm is automatically downloaded into the system and then spreads over the network. It was a VBScript program with the text file extension of . vbs that can destroy many types of files such as JPEG, MP3, JS, CSS, WSH and HTA.

4. code EXPLANATION: When ILOVEYOU is run, it first copies MSKernel32.vbs and LOVE-LETTER-FOR-YOU.TXT.vbs to the Windows system directory. It also saves itself as Win32DLL.vbs in the Windows directory.

5. code EXPLANATION: It registers itself in the registry to be run when the system is restarted.

6. code EXPLANATION: The worm then replaces the Microsoft Internet Explorer home page with a link to WIN-BUGSFIX.exe, an executable application. If you download the file, the worm adds it to the registry, forcing the software to run when you restart your computer . The ILOVEYOU virus also checks for the "WinFAT32“ to make it active every time the Window Starts.

7. code EXPLANATION: The virus then scans all folders on all local and distant disks for specific file types and overwrites them with its own code. The files that are rewritten contain the extensions.vbs or.vbe. For all files with the following extensions:. js ,. jse ,. css ,. wsh ,. sct , and.hta, the virus will produce a new file with the same name but a.vbs extension and erase the original.

8. code EXPLANATION: All files with the extensions.jpg,.jpeg,.mp3, and.mp2 get a new file added next to them, and the original gets deleted. The virus, for example, will produce a new file called pic.jpg.vbs and erase the original for a photo named pic.jpg.

9. code EXPLANATION: this is the code for the sending the ILOVEYOU virus from one computer to another through an email.

10. code EXPLANATION: this is the code for the sending the ILOVEYOU virus from one computer to another through an email.

11. How thus this virus penetrates computer? The virus was spread through an E-mail attachment designed to propagate the virus message automatically throughout an agency's Global Email Address Directory. Unsuspecting users who opened the attachment. The ILOVEYOU virus comes in an email with "ILOVEYOU" in the subject line and contains an attachment that, when opened, results in the message being re-sent to everyone in the recipient's Microsoft Outlook address book. Perhaps more seriously, it results in the loss of every JPEG, MP3 and certain other files on all recipients' hard disks

12. What will be the possible effects? Is a computer worm that infected over ten million Windows personal computers on and after 5 May 2000 when it started spreading as an email message with the subject line "ILOVEYOU" and the attachment " LOVE-LETTERFOR-YOU.TXT.vbs " The latter file extension (' vbs '), a type of interpreted file), was most often hidden by default on Windows computers of the time (as it is an extension for a file type that is known by Windows), leading unwitting users to think it was a normal text file. Opening the attachment activates the Visual Basic script.

13. What will be the possible effects? The worm inflicts damage on the local machine, overwriting random types of files (including Office files, image files, and audio files; however, after overwriting MP3 files the virus hides the file), and sends a copy of itself to all addresses in the Windows Address Book used by Microsoft Outlook. This made it spread much faster than any other previous email worm .
