Description
This test verifies that the endpoint attempting to connect to your system has anti-spyware tools
installed and that the anti-spyware definitions are up-to-date.
Test Properties
Select the anti-spyware software allowed on your network. Any endpoint that does not have at least
one of the anti-spyware software packages selected will fail this test. You can also enter a value in
the
Last scan performed within
text field, which requires the anti-spyware software to
have executed a scan on the endpoint within the set number of days.
How Does this Affect Me?
Spyware is software that gathers and transmits information (about the user, computer, and/or
network) without the user's knowledge. It is usually installed without the user's knowledge through
seemingly harmless downloads such as freeware, shareware, instant messages, and email
attachments. Spyware is intentionally difficult to detect and remove. Those who create and release
spyware don't want you to know it's there or be able to easily uninstall it. The information gathered
can be exploited for mischief, for financial gain, and for gaining unauthorized access to your
network. Spyware also consumes system resources and can cause system instability and crashes.
What Do I Need to Do?
Make sure you have an anti-spyware program installed, that the spyware definitions are kept up-to-
date, and that your system is scanned often.

Description
This test verifies that the endpoint attempting to connect to your system has the latest anti-virus
software installed, that it is running, and that the virus definitions are up-to-date.
Test Properties
Select the anti-virus software allowed on your network. Any endpoint that does not have at least one
of the anti-virus software packages selected will fail this test.
How Does this Affect Me?
Anti-virus software scans your computer, email, and other files for known viruses, worms, and
trojan horses. It searches for known files and automatically removes them. A virus is a program that
infects other programs and files and can spread when a user opens a program or file containing the
virus. A virus needs a host (the program or file) to spread.
