Even if your computer has a powerful antivirus, it would be better to save your files to media devices such as CD or floppy disk. To do that, you need Floppy Base.
Floppy Base is a program which allows you to get an exact copy of your disk by converting the data into a compressed image file. This program can write the images at a speed of 720k in a media file of 1.2MB to 1.44MB. Then, you can burn these images to CD or save them to floppy disks. Floppy Base can provide a perfect copy of the disk by keeping all the original data of the file system. It is a shareware version but can be tested freely during one moth.
