pls tell some idea to take backup of virus infeced hard disk
ISO file cannot be infected by virus
The abbreviation D2D means Disk to disk backup. It is computer lingo. It is basically importing data from a hard disk to any other type of disk. The disk it is copied to is called a backup disk.
A backup disk is a place to store important information that may be in danger of getting wiped from a computer hard drive in the event of a virus attack or an accident. With the innovation of online storage, backup disks are becoming obsolete.
No, Not unless it was a "disk image"backup.
No. If the hard disk crashes you will lose both the original and backup data. It is best to backup to separate disk for redundancy purposes.
Stealth viruses are designed to hide on disks to avoid being detected by virus scanners. You must block stealth viruses from hiding, so your scanner can find and remove them.Steps to remove stealth virusesUpdate your anti-virus software.Save a copy of your virus scanner onto a clean floppy disk. (You might need this backup file if the scanner on your hard drive is infected.)Insert the floppy disk into the drive in a locked position; this should block a virus from hiding within the floppy drive.Run your anti-virus software. If the clean, locked floppy is in the drive, you should be able to detect and remove a stealth virus.Check if your scanner program is infected. And if it is, use the backup program on the floppy to scan for viruses.Shut down your computer to clear the memory, and then reboot. Now that the virus is out of the memory, your computer should be safe.
If by disk based backup one means making a back up into a CD or DVD, then the advantage would be that even if the hard drive fails, one can still restore the backup version from the disk.

You can check your hard disk's memory and search string by string for the virus, or if you don't want to spend that time, format it. Although the latter will delete EVERYTHING.
It might be your OS is crashed or may be RAM is not working properly. Please inspect all the hardware carefully then try.
