Using the VShield Scanner
Configuring the Internet Filter module
Dangerous objects such as these can often lurk on websites until you visit and
download them to your system, usually without realizing that they exist. Most
browser software includes a feature that allows you to block Java applets or
ActiveX controls altogether, or to turn on security features that authenticate
objects before downloading them to your system. But these approaches can
deprive you of the interactive benefits of websites you visit by
indiscriminately blocking all objects, dangerous or not.
The Internet Filter module allows a more judicious approach. It uses an
up-to-date database of objects known to cause harm to screen Java classes and
ActiveX controls you encounter as you browse.
When it finds a virus, the module can ask you what you want it to do, or it can
block the dangerous object or site automatically. You can have it report what
it has done either with an alert message when it takes the action or in a log file
you can examine at your leisure.
To choose your options, click the Internet Filter icon at the left side of the
VShield Properties dialog box to display the property pages for this module.

Choosing Detection options
The Internet Filter module starts by assuming that you want to block all of the
harmful objects and sites it has listed in its database in order to prevent you
from accidentally encountering them
with the tightest security against harmful objects, but allows you to make use
of other objects on the Internet sites you visit.

Although both Java and ActiveX objects include safeguards
designed to prevent harm to your computer system, determined
programmers have developed objects that exploit arcane Java or
ActiveX features to cause various sorts of harm to your system.
