First of all Norton Bootable Recovery Tool is integrated with Windows Preinstallation Environment (WinPE).
So basically its scans your pc and the windows based partitions like fat32 and ntfs and makes your computer little slower, secondly it can not check linux partitions .even it wont detect it for consideration .As linux uses ext format of partition.
So there is nothing for Norton Bootable Recovery to look inside linux partition as it cant.
One of the biggest advantage of any linux distro over windows is they cant be affected by any virus easily, there is a rare chance of that , means you probably dont have to care about viruses in linux.
Hope thats what you wanted to know.
