Computer viruses can be very frustrating most times. Although there are free antivirus software’s available for downloads, they are not always efficient in removing the unyielding viruses that goes deep into the recesses of the windows operating systems. A computer user is usually faced with the necessity to get rid of these pesky viruses. Formatting the Hard Drive can be said to be among the best options to get rid of these stubborn viruses, which is if the computer user cold still boot up the computer operating system. This approach can effectively remove all of the possible viruses infecting the computer because all the data in the hard drive are erased though this can be disastrous if your files are not backed up. This process is usually known as a ‘shotgun approach’ where the computer user is not aiming to clean only certain files in the computer but all of those present in the hard drive. Though, it will take considerable amount time to format the hard drive since it will be very slow and in some cases take more than a day. The computer user will need to start all over again to reinstall the operating system and the different applications formally present on the computer system to be able to use the computer. Also, this prevents the computer user from saving his important files as they might have been lost in the cause of formatting the system. So what would be the best option when faced with this type of situation? The best approach is to use a rescue disk.
What are Rescue Disks
Rescue disks are bootable disks that aids in managing your system, this means that these disks are capable of running the computer system by itself as a CD software package. Rescue disks tend to take over the management of the windows computer system and are present in all versions such as those provided by the windows operating systems like Windows XP, Windows Vista, Windows 7, Windows 8 and even the windows 10. These CD software are package in rescue disks contain utilities. Utilities are applications which allow the computer user manage the computer files in such a manner he deems it fit such as copying, deleting, or moving files in and out of the computer system. If the computer user could not gain access to the computer files due to the failure of the windows operating system to boot up due to a virus infection, using these utilities gives him absolute access to do so. Utilities also include virus scanners and debuggers which run deeply than the conventional antivirus programs. The rescue disk also includes virus scanners that can isolate the virus files which the computer user can access to erase it manually. Below are some great ways to remove viruses from your computer system using a rescue disk.
Kaspersky Rescue Disk
One of the best bootable rescue disks in the market right now is the Kaspersky Rescue Disk. The Kaspersky Rescue Disk is based on a Linux kernel and it operates under a Linux operating system environment. Linux operating systems are virtually immune to viruses that attack windows operating system. The Kaspersky Rescue Disk is usually done using the Kaspersky Antivirus software program or downloaded from free sites on the internet. To make a Kaspersky Rescue Disk, the computer needs to burn the saved iso file using a CD burning tools such as Nero and the likes. An iso file is unlike the normal conventional applications file this is because it cannot be run on a computer while operating under a windows operating system. A computer user needs to reboot the infected computer before using the Kaspersky Rescue Disk.
Change the Boot Sequence of the Computer
In order for the Kaspersky rescue disk or any of your favorite bootable rescue disk created from an antivirus program to work on your computer system, it will required that you change the boot sequence of the computer. This is done by activating the BIOS (basic input/output system) CMOS (Complementary metal–oxide–semiconductor) Setup Utility of the computer. BIOS are the first code runned by the computer system when it’s powered on. For it to be accessed, it would be needed that the computer user reboots the computer system while pressing either the F2 or delete button. Usually, a large bright blue interface will be seen as an indication of it working. Scroll down using the arrow key until the Advanced BIOS Features (this may vary between computers) is shown on the screen then hit Enter, next you look to find the First Boot Device menu also hit Enter then change the first booting device to CD-ROM instead of the normal HDD-0 or the hard drive that is seen. Set the hard drive or HDD-0 as the 2nd Boot Device. Hit the Esc key and find the Save and Exit Setup menu then press Enter then type Y to confirm the changes that has been made. Finally you will allow the computer to reboot with the Kaspersky rescue CD in the CD/DVD drive. Your computer system will now reboot using the rescue CD. Watch your screen as you may need to hit any key as stated on the computer screen so as to reboot using the CD-ROM.
You will note then that the computer will now reboot with the Linux kernel loading, which will be unlike the way you boot using a windows operating system. You will be required to press Enter to load the Linux kernel of Kaspersky Rescue Disk. Keep an eye on the Linux kernel load line by line (usually white text against a black background). After a few minutes, again as before a large blue green background will be displayed where you will notice a large arrow asking you to scan the computer or update the virus database. If the downloaded you made is the latest Kaspersky Rescue Disk release, you may begin to directly scan for any virus. But if that is not the case, you will then be required to update the virus database of which it takes a lot of time. If have decided to go ahead to do the scan, you may then scan any or all the computer files such as the boot sector, the C disk, Drive C or root hard drive or possibly a Drive D virtual hard drive. Then continue by selecting all of the radio buttons and do a full scan on the computer by clicking the scan folder. The computer systems will then scan and identify the unyielding pesky virus inside your computer system then it will ask for you to confirm deletion of the virus file. You may also choose to hit the Fix It Now button after doing the whole scan so the computer will automatically remove all difficulties in deleting all viruses. After which all of these procedures are finally done, you may now proceed to reboot your computer system using the saved operating system stored in the hard disk. Finally you can then remove the Kaspersky Rescue Disk from the CD/DVD drive so that the computer system can be able to use the hard drive as its second boot device to boot the windows operating system.
All virus or viruses should have been eradicated from the computer system by the time the windows operating system boots up and displays the screen. But if after doing all this you still see that the virus is still there in your computer system, you will have no option but to format the hard drive totally. Before formatting the hard drive, you can use the Kaspersky Rescue Disk to copy all your files to an external flash drive using any File Manager utility that is compatible with the Kaspersky Rescue Disk package.
