Ultimate Boot CD

Hi all
I'm trying an antivirus scan on a NTFS partition. Anyway if I enable the NTFS in any of the antivirus in UBCD 3.4, i have several error mesages like "out of memory while processing file wget.cab". Then I have a DOS prompt and no scan made. If I don't enable the NTFS my FAT32 partition are regularly scanned. What do I have to do to scan my NTFS partitions?
thanks for help

Try this: do't enable NTFS during the boot process. But once it finishes loading and the DOS prompt appear, type NTFSDOS at the command prompt. Sometimes it works this way.
