13.1 Updating the Virus Scanner

sures that infected data will not be burned. We recommend that you update the virus scan-
ner database regularly. The database is updated via an Internet connection.
The following requirement must be satisfied to update the virus scanner:
 An active Internet connection must exist.

13.2 Erasing a Rewritable Disc
Nero BackItUp can be used to erase rewritable discs, i.e. discs with the RW specification, as
long as your recorder supports this feature. The following disc types are supported when
erasing a rewritable disc: CD-RW, DVD+RW, DVD-RW, and DVD-RAM.
The following erase methods are available:
Quick erasing does not remove the data physically from the disc, but instead only makes it
inaccessible by erasing the references to existing content. The data can be restored!
Full erasing removes the data from the disc by overwriting it with zeroes. The contents can-
not be restored with conventional methods. Repeated full erasing increases the probability
that third parties will not be able to reconstruct the contents.
To erase a rewritable disc, proceed as follows:
1. Insert a rewritable disc whose content you want to erase.
2. Click the Tools menu followed by Erase Rewritable Disc.
 The Erase Rewritable Disk window opens.
