Live AntiVirus and Recovery Discs

These are links to free ISO files that you can use to create bootable discs that can clean an infected Windows system.

Important

• Once your system has been compromised, you can never be 100% certain that there is nothing still lurking in the OS, watching everything you do.
• You should backup your data, format the hard drive, and do a clean installation of the OS and applications from CD/DVD's that you know are clean.
• You can use a Live disc to backup your important personal files (documents, correspondence, photos, etc.).

To Scan and Clean

From a computer that you know is free of any malware:

1. Download the ISO
2. Create/burn a bootable optical disc from the ISO

On the afflicted PC,

1. Insert the Live disc into the affected PC
2. Turn off the affected PC
3. Turn on the affected PC and select the option to boot from the CD/DVD/Optical drive, and boot from the Live disc
   • For Dell systems: Press F12 when it's just starting to display the "One-time boot menu," then select "CD/DVD/CD-RW Drive" to boot from the CD
4. Use the Live disc to scan and clean the system

Downloads

Note: Automatic means the disc will automatically start downloading the latest updates if Internet access is available. Manual means that you have to initiate the update process once the application has loaded, before you start scanning.

Unhide Files After Trojan/Malware Aftermath

This is how to recover after a malware infection hides directories and files, and may also add shortcuts with the names of the hidden directories.

To un-hide the directories/folders and files:

1. Insert your affected USB flash drive into the PC, and make a note of the drive letter assigned to it.
2. Open a command prompt and type the following command, and then press ENTER:

attrib -h -r -s /s /d X:\*.* 

(Replace X: with the drive letter of your flash drive.)

• -H Clears the hidden file attribute
• -R Clears the Read-only file attribute
• -S Clears the system file attribute
• /S Process matching files in the current directory and all subdirectories
• /D Process folders as well.

You'll need to also delete all the bogus shortcuts using the following command, and then press ENTER:

X:\del /a /f *.lnk/s
