Using ActiveShield

Scanning for scripts

VirusScan monitors your computer for suspect activity that might indicate a threat
is present on your computer. While VirusScan cleans viruses and other threats,
ScriptStopperTM prevents Trojan horses from running scripts that spread viruses
further.

A “Trojan horse” is a suspect program that pretends to be a benign application.
Trojans are not viruses because they do not replicate, but they can be just as
destructive.

The ScriptStopper protection mechanism detects, alerts, and blocks suspect
activity. Suspect activity might include the following action on your computer:

A script execution that results in the creation, copying, or deletion of files, or
the opening of your Windows registry

If you set ActiveShield to use the default

Enable ScriptStopper (recommended)

option in the

Advanced Options

dialog box, ScriptStopper monitors script

execution for suspect patterns and alerts you when a specified number of e-mails
or recipients has been exceeded within a specified interval.

To set ActiveShield to scan running scripts for worm-like activity:

1

Right-click the McAfee icon, point to

VirusScan

, then click

Options

.

2

Click

Advanced

, then click the

Exploits

tab (

).

3

Click

Enable ScriptStopper (recommended)

, then click

OK

.
