Comodo Rescue Disk

Comodo Rescue Disk (CRD) is a bootable disk image that allows users to run virus scans in a pre-boot environment. It is a powerful virus, spyware and rootkit cleaner which works in both GUI and text mode. CRD can provide a more comprehensive and thorough scan than regular malware cleaning applications because it cleans your system before Windows is loaded.

CRD is intended to be used when malware embeds itself so deeply into your system that regular AV software cannot remove it. The rescue disk is also very effective at removing infections that are preventing Windows from booting in the first place. Apart from the virus scanner, CRD also provides tools to explore files in your hard drive, take screenshot and browse web pages.

Comodo Rescue Disk is an invaluable addition to any computer owner's security toolkit and forms a great complement to 'regular' AV software such as Comodo Antivirus.

Why should I use Comodo Rescue Disk?

Sometimes, viruses and other malware get embedded so deeply into Windows that they cannot be cleaned by 'regular' anti-virus software running in a Windows environment. You can find and remove these buried threats by booting your computer to CRD and running a virus scan of your system before Windows boots up.

Can you tell me more about the malware scanner?

The on-demand malware scanner uses the same core engine as Comodo Antivirus but does not require installation and can be run directly from removal media such as a USB stick. Awarded Virus Bulletin VB100 status, the scanning engine uses the very latest heuristic techniques to identify previously unknown, zero day threats with an very high level of efficiency. The scanner is also extremely effective at disinfecting and removing viruses once they have been identified.

How do I get my computer to boot to CRD?

After using the CRD ISO to create your bootable CD/DVD/USB drive, you next need to make sure the BIOS is set to boot from the correct drive. In most cases, this will require you to manually prioritize the CD/DVD/USB as the boot drive ahead of your usual C: drive. To make this change, you first have to access your computer’s BIOS configuration utility.

While the specifics vary from computer to computer, the following steps should be of use to most users:

• Place the CD/DVD in your drive or insert the USB key as appropriate
• Shut down your computer. Note – do a full shut down. A soft restart will not clear memory and the BIOS setup might not appear.
• Turn your computer back on and be ready to react quickly. During system start up, you will see a message similar to one of the following:
  
  

  Press <key> to enter setup
  
  Or
  
  Press <key> to open bios configuration utility
  
  Or
  
  Press <key> to change boot order
  
  

  It is usually one of the F1 – F12 keys or the DEL key (F2 and DEL are popular).
  
  Quickly press whichever key you are requested to press. If you miss it this time, simply try again by shutting down then starting your computer.
• Having hit the correct key, the bios configuration utility will start. Look for an entry that states 'Boot Order', 'Change Boot Order', 'Change Boot Sequence' or similar. Select it and press enter.
• Use the arrow keys to select the CD/DVD drive or USB port that you wish to boot from. If you are shown a sequential boot order, make sure CD/DVD/USB (as applicable) is first on the list.
• Save and exit. Your machine should automatically reboot to the CRD drive, allowing you to use the program.

Note – if these instructions do not help then please consult your system manufacturer's website (or call their support) for more details on how to change boot order.

Can I use CRD to boot and clean Linux machines?

Yes. CRD itself even runs on a lightweight distribution of the Linux operating system.

What is a portable application?

Portable applications do not need to be installed and can be run directly from media such as a USB stick.
