This virus i s from our very own NIIT center residency road.AS i was inserting the usb it installed some software and made the system to reboot.But i did't care much about the virus as i thought i could use LINUX to to remove it .
BUT...star age thing hapen.it is not allowing to mount the USB.And justin also did his best to get that thing to remove..but i t is not allowing it and it says acess dened.
will be continued..................

Insert your USB pen drive. Let it get detected and mounted. Open Terminal. Type The Following commands 1. dmesg |tail –> here the ‘|’ key is the pipe, ie, the key before the backspace key(the upper one, so press shift) You’ll get something like
sathya@shaman:~$ dmesg |tail [ 9921.681164] sda: Write Protect is off [ 9921.681174] sda: Mode Sense: 23 00 00 00 [ 9921.681178] sda: assuming drive cache: write through [ 9921.709138] SCSI device sda: 4030464 512-byte hdwr sectors (2064 MB) [ 9921.720951] sda: Write Protect is off [ 9921.720963] sda: Mode Sense: 23 00 00 00 [ 9921.720967] sda: assuming drive cache: write through [ 9921.721225] sda: [ 9921.727896] sd 0:0:0:0: Attached scsi removable disk sda [ 9921.744187] sd 0:0:0:0: Attached scsi generic sg0 type 0 Note the terms in bold. In your system it will be different, maybe sdb or something. Whatever it may be, make sure to substitute it in the commands below, else your hard disk may get formatted.
2. Unmount your pen drive by using sudo umount /dev/sda (In your case, please substitute sda with the appropriate device, listed above.
3. use the mkfs.vfat command to format to FAT32 filesystem, or mkfs.ext3 to format to ext3 filesystem sudo mkfs.vfat -n ‘Label’ -I /dev/sda Replace Label with the name you want the pen drive to have.
4. That’s it! When done formatting, you’ll be returned to the prompt sathya@shaman:~$ mkfs.vfat -n ’sathya’ -I /dev/sda mkfs.vfat 2.11 (12 Mar 2005) sathya@shaman:~$
Remove and insert the pen drive to have mounted again!
