How to Make a Bootable Antivirus Disc

Purpose of this document.
This document will teach you how to make a bootable anti-malware ( bootable antivirus ) cd/dvd step-by-step.

Why Bootable Antivirus?
In a bootable environment we are running a stripped down version of windows in a ram disk (programs are loaded directly into ram), thus the hard drive on the PC is treated as attached storage (like a flash drive). In this state malware (malware consists of viruses, trojans, spyware, adware, rootkits, etc) is helpless and totally at your mercy. This is the best free way to remove any piece of malware with a 100% success rate.

Steps:
Please follow all the steps below:

1. Go to http://ubcd4win.com/downloads.htm
2. Select a mirror with a green status. (like "Mirror#3" for example)
3. When you click on the mirror it will take you to another site where the download will be available.
4. Click the download link for Ultimate Boot CD and save the download to wherever you download stuff.
5. Once the installer has been downloaded double click it.
6. Choose your language
7. Click next about 3 more times and select the file path where you would like to install ultimate boot cd 4 win. Please note that you should have a drive with at least 5-10 gb of free space to allow for future plugin growth. I will choose C:UBCD4Win. The install should take a few minutes.
8. Click Yes to the MD5 Hash Check. The install will continue once the hash check succeeds.
9. Click Yes to see if a patch file exists.
10. Click the checkbox to launch ubcd4winbuilder.exe.
11. Click the "i agree" button.
12. Click "NO" to searching for windows files.
13. Obtain a windows xp operating system disc w/SP2.
14. Explore the disc and copy the entire content (all the folders and files on the windows xp cd) to any location on your computer. You should allocate at least 700 MB of free space for the windows xp disc.
15. Open UBCD4win (if it's not already open). Click Source browse button (3 dots ...) and browse to your i386 folder. My path was C:WindowsXPcd for example.
16. Next go to the media output section and choose a spot for your ISO image to be created. This ISO can be burned with almost any burning software. Once the ISO is burned it will be bootable.
17. Next, click the plugins button. Don't be too overwhelmed here, actually you should be very happy! Look at all those plugins!
18. Now it's time to update our anti-malware software packages.
19. The first one I have on my list is a-squared free anti-spyware. Click that line and then click the config button. A command prompt will automatically open and start downloading the latest updates for that program...totally awesome, isn't it!
20. So, now you need to update all the anti-malware programs in our plugin list. Click each one and then hit the config button.
21. After you're done configing/updating your plugins click the close button.
22. Next, click Build.
23. Click yes to create a directory and then click i agree.
24. At this point your ISO is created and is ready to be burned.

This concludes the How to Make a Bootable Antivirus CD tutorial.

Types of Computer Hardware

Types of Computer Hardware

Computer hardware is a physical part of a computer that executes within the hardware. It is unlike computer software or data that can be frequently changed, modified or erased on a computer. Computer hardware is not frequently changed and so is stored in hardware devices such as read only memory (ROM) where it is not readily changed.

Most computer hardware is embedded and so is not visible to normal users. Below are the different types of hardware's found in a computer.

Motherboard: It is the central or primary circuit board making up a complex electronic system such as a computer. A motherboard is also known as a main board, logic board or system board.

Central processing Unit: A CPU is the main component of a digital computer that interprets instructions and process data in computer programs.

Random Access Memory: A RAM allows the stored data to be accessed in any order. RAM is considered as the main memory of the computer where the working area is used for displaying and manipulating data.

Basic Input Output System: BIOS prepares the software programs to load, execute and control the computer.

Power Supply: Power Supply supplies electrical energy to an output load or group of loads.

Video Display Controller: It converts the logical representation of visual information into a signal that can be used as input for a display medium.

Computer Bus: It is used to transfer data or power between computer components inside a computer or between computers.

CD-ROM drive: It contains data accessible by a computer

Floppy disk: It is a data storage device

Zip Drive: It is a medium capacity removable disk storage system.

Hard Disk: It is a non-volatile data storage system that stores data on a magnetic surface layered unto hard disk platters.
