NETSCAN v63-B by McAfee Assoc. REGISTRATION $ .....
UTIL JUL90 NETSCAN MCAFEE VIRUS PROTECTION
FILES: netsc63b.sdn
NETSCAN is the network version of VIRUSCAN. It scans network
virtual drives and identifies any pre-existing PC virus
infection in the file servers. NETSCAN will indicate the
specific files or system areas that are infected and will
identify the virus strain which has caused the infection.
Removal can then be done manually or, if the infection is
widespread, automatic removal utilities are available which
can disinfect each virus strain.
NETSCAN version V63, when used in conjunction with VIRUSCAN
on the individual workstations, can identify 97 major virus
strains and numerous sub-varieties for each strain. The 97
viruses include the twelve most common viruses which account
for over 95% of all reported PC infections. The complete
list of viruses detected is included in the accompanying
file: VIRLIST.TXT.
It is important to note that existing virus strains can be
grouped and counted differently than the ordering outlined in
VIRLIST.TXT. DEN ZUK, for example has two separate
versions. Likewise, the STONED, VIENNA, ALAMEDA and
JERUSALEM-B viruses have been modified a number of times.
Some researchers would define each of these modifications, or
sub-varieties, as separate viruses. NETSCAN chooses to group
them as the same virus, because the same scan string can
identify each of them. This is only done if disinfection
requirements for the different sub-varieties are identical.
If removal procedures differ for different varieties, then
NETSCAN will differentiate between them.
These viruses infect one of the following areas: The hard
disk partition table; the DOS boot sector of hard disks or
floppies; or one or more executable files within the system.
The executable files may be operating system programs, system
device drivers, .COM files, .EXE files, overlay files or any
other file which can be loaded into memory and executed.
NETSCAN, when used in conjunction with VIRUSCAN on the
workstations, identifies every area or file that has become
infected and indicates the name of the virus that has
infected each file.
