What To Do
Obtaining and preparing the tool
- At an uninfected Windows computer with access to a CD burner, CD burning software and an Internet connection download the tool from:
- Save the downloaded sbav_10_sfx file to your computer's desktop.
- Create the Sophos Bootable Anti-Virus disc by following the instructions as shown below.
Create the CD
- Double-click on the sbav_10_sfx file to install the SBAV CD creator application, the License Agreement and the Release Notes.
- Accept the License Agreement, and then specify the installation location make a note of it. (The default is C:\SBAV).
- Open a command prompt (Start | Run | Type:
cmd.exe | Press return).
:\sbav10 (or replace C:\SBAV with the location you noted in step 2. SBAV assumes that you are working from the C: drive, so if the location is in another drive, you will have to change directories first).
- Press Enter.
sbavc.exe sbav.iso (replace sbav.iso with another name for the CD, if desired) and press Enter. The program will go through a series of steps:
- It downloads the Linux distribution from Sophos and verifies its contents (approximately 100MB)
- It downloads Sophos Anti-Virus for Linux and verifies it (approximately 50MB)
- It downloads the latest IDE files (approximately 500kB)
- It creates the .iso file in the folder that you specified in step 2.
- Close the Command Prompt window.
- In Windows, open the CD burning software application and burn the .iso file to disk.
- You must select the option to 'create a disk image'; do NOT select the option 'create a bootable CD' - the image you are burning is already a bootable disc.
- Sophos cannot recommend or support the use of a third-party CD burning application however if you have Windows 7 you may wish to see: Microsoft: Burn a CD or DVD from an ISO file.
- For Windows 2003 see article 111351.
When you have created the CD to use on your infected computer, see article 52053.
