Norton AntiVirus nested file manual scan bypass.....

Product Version: Norton Antivirus 2002 (~Only tested
On...~)
Risk Impact: Medium

Summary:

If you manage to inject a file in the
sub-directory(s); beyond windows OS can create
normally, [ say in 130 'th + sub-directory at
c:\..\..\..\....upto 130'th ... ] NAV fails to scan
the NESTED FILE. Indeed, it's more a windows
restriction in accesing the nested file than a
ANTIVIRUS flaw. Other antivirus product should also
suffer the same. *.PLEASE VERIFY.* NAV
