Using the Command-Line Scanner
The command-line scanner is a program that you can run from a command prompt. If
the scanner has been added to
PATH
or is in the current directory, you can run a scan
by typing
SCAN
at the command prompt with the options you want. For a complete list
of options, see
page 25
.
You should scan any file that is new to your computer, especially any newly
downloaded or installed files. If your computers are susceptible to infection, you should
scan as often as once a day. The scanner operates with minimal use of system
resources.
The following features offer optimum protection for your computer and network:
On-demand scanning options let you start a scan immediately or schedule
automatic scans.
Advanced heuristic analysis detects previously unknown macro viruses and
program viruses.
Updates to virus definition files and upgrades to program components ensure that
the program has the most current scanning technology to deal with threats as they
emerge.
Later sections in this guide describe each of these features in detail.
The command-line scanner also includes options for administrators that help to ensure
that the scanner is being used most efficiently. For example, the
/FREQUENCY
option (on
page 27
) sets a mandatory period between scans, which helps to minimize resources
when the network is most busy.
