Product Highlights

McAfee's WebScan protects against virus infections to your system
from files attached to your mail messages or files you download
from the Internet. Here are the main functions of WebScan:

- Virus protection--the anti-virus function of WebScan is activated
  anytime you download executable and Microsoft Word document files
  from the Internet or save these types of files to disk from a
  Pegasus Mail message attachment.

- Electronic mail through Pegasus Mail, which is designed for ease-of-use,
  with maximum power and functionality. Pegasus Mail is a popular electronic
  mail system with over 4 million users.

- SPRY Mosaic is the WebScan Web browser. It is a sophisticated graphical
  Internet browsing application that gives you access to the Internet. It is
  automatically installed on your system, and can also be launched from
  Pegasus Mail, so that you have an instant Internet connection.


________________________________________________
What's the difference between retail and online?

The version of WebScan you buy in the store (retail) and the one you
download from a McAfee online service are basically the same. However,
please note that only the retail version offers these features:

- Ability to choose a Internet service provider other than InterServ
  (Compuserv). If you purchased the online version, Internet access
  is ONLY available through InterServ.

- Secured Internet transactions is available ONLY with the retail
  WebScan product. The online version does not offer secure HTTP.

- Pegasus Mail encryption capabilities are offered ONLY with the
  retail WebScan product.


____________
Installation

Review these basic requirements for installing and running WebScan.

- Windows 3.1x, Windows 95, or Windows NT
- CONFIG.SYS set to at least FILES=50
- Internet access through a LAN, or using a modem capable of
  9600 baud or faster and connected to a telephone line
- External modems powered on, if you use this type of modem
- Note the communications port to which the modem is connected.

Your main steps for completing the WebScan installation are:

- Start the Installer and identify the destination for copying
  files.

- Identify the Web browsers to which you want to add the anti-virus
  component, WebSafe.

- Enter configuration information for SPRY Mosaic Web Browser.

- Set up the Pegasus Mail component.

Read the following paragraphs for details about installing from diskette
or from the BBS and McAfee Web site.


FROM DISKETTE

If you purchased the retail version of WebScan, you received four diskettes.
You also received a printed "Getting Started" guide that you can use to
supplement the installation procedure.

To install, insert Disk 1 and then enter the following command in the
Windows Run box:

x:setup

where x is the drive that contains the diskette.

Then follow the instructions on the installation dialogs.


FROM THE BBS OR WEB SITE

WebScan is available from the BBS or the McAfee Web site
(www.mcafee.com). You'll need to download these files:

WBS100E0.ZIP
WBS100E1.ZIP
WBS100E2.ZIP
WBS100E3.ZIP
WBS100E4.ZIP

Decompressing Your Files:

Use PKUNZIP to decompress the WebScan product files
either onto floppy diskettes or into a directory on your
hard drive or server. These files are automatically copied
into the appropriate directory structure when you unzip them.

Before you install, you'll want to verify that the files you
downloaded are exactly the same as when we posted them online.
We recommend you perform this task for maximum anti-virus
protection. Read the following paragraphs to learn how to
validate your file.


Validating Your Files:

Included in the files you downloaded is the Validate program
(version 2.0.1). Validate is a file-authentication program that
you can use to check program files for signs of tampering.
Validate uses two methods of generating Cyclic Redundancy Checks
(CRC's), and then displays the information so you can compare
these statistics against the "known value" for the program files.
The dual CRC checking provides a high degree of security.
The known value you use for validation is usually provided by the
author of the program, or you may receive it from a trusted
information database.  You can find the statistics for
WebScan in the file PACKING.LST.

To confirm that a program file has not been tampered with, run the
Validate program and then record the validation data produced.
Compare this data against the file statistics the program author has
specified. If the information matches, most likely the program
has not been modified since McAfee put the files online.


To run VALIDATE, enter the following command:

     VALIDATE <path spec>

where <pathspec> is the name of a directory and file. (The
wildcard characters, "*" and "?", can be used when specifying
<pathspec>.)

The VALIDATE program displays the following information:

     <name of directory>
     name of file (starting at row 1)
     extension of file (starting at row 10)
     size of file (starting at row 15)
     date of file (starting at row 25)
     time of file (starting at row 35)
     check method 1 (starting at row 44)
     check method 2 (starting at row 51)
     SAMPLE   TXT  12345678  01-01-80  12:01a   1A2B   3C4D
     <number> file(s) have been validated.



Starting the Install Program:

Before you install, we recommend that you access the online
"Getting Started" manual which contains installation instructions.
To do this follow the steps below:

   *  Start the Acrobat Reader.

      NOTE: If you do not already have the Acrobat Reader, you can
      download it from the McAfee home page located at www.mcafee.com.
      Once you arrive at the home page, just select 'Download McAfee,'
      'Download McAfee Product,' and get the file ACROREAD from the
      utility area. Then run ACROREAD.EXE and follow the instructions
      on the screen to install the reader.

   *  Open the WEBTOC.PDF file from the DISK0 directory.

   *  Click on the chapter containing the information you'd like to view.


To install WebScan after downloading the product files:

- Run SETUP.EXE, located on either the first diskette or in the DISK1
  directory, depending on the destination to which you decompressed the files. 

- When you are prompted for Disk 2, either place the second diskette into
  the drive or change the directory name to DISK2 and click OK.

Using the WebScan Anti-virus Feature


WHEN TO SCAN

For WebScan to perform virus checks successfully, you need to select
one file at a time to download. If you select a second file to
download while the first is being scanned, an error message is displayed.


WHAT GETS SCANNED

WebScan checks for and alerts you to viruses in executable program files and
in Microsoft Word document files. WebScan determines whether files are
executables or documents based on the data type identified in your Browser.
For example, Microsoft Word document files are usually identified as the
data type 'application/msword'.

At the time of this release, WebScan checks the following data types
for viruses:

    NOTE: We are continually adding to the list of data types checked.

application/octet-stream
application/octet-string
application/x-msdownload
application/msword
application/x-zip-compressed
application/zip

Refer to your Browser documentation if you need to specify a different
data type for downloading files.


ADDING WEBSCAN TO A WEB BROWSER

The WebScan anti-virus component, WebSafe, is automatically added and has been
tested with the following Web browsers:

- NetScape Navigator (16-bit version for Windows 3.x and Windows 95;
  the 32-bit version is not supported)
- All versions of SPRY Mosaic
- Netcom NetCruiser.

However, you can add WebSafe to Web browsers other than those listed above.
You can use the following procedure as a guide.

    NOTE: We recommend that you do not install WebSafe to the Microsoft Internet
    Browser. We are currently experiencing unpredictable results during our testing.
    However, WebSafe may be compatible with this browser in a future release.

FOR QUARTERDECK QMosaic
   * Select Tools/Preferences
   * Display the Data Engine tab page
   * Select a data type (for example, Application Octet-stream)
   * Click on External Viewer Application
   * Click in the text box and enter the following command

	x:\MCAFEE\WEBSCAN\AV\WEBSCAN.EXE /SAVE /BUSY

     where x: is the drive that contains the \MCAFEE directory

	NOTE: Be careful to click in the text box first before you
	begin typing, since the MIMEtypes have speed search!


FOR AMERICA ONLINE (2.5 Windows only)
   *  Browse the Web
   *  Click the Prefs button
   *  Click the Helper Apps button at top right to display the "Modify" dialog
   *  Click Use Separate Application and browse for WEBSCAN.EXE (it is installed
	under the directory \MCAFEE\WEBSCAN\AV)
   *  Enter the switches /SAVE /BUSY after WEBSCAN.EXE
   *  Save the settings.


______________________________________________
Switching from a Network Connection to a Modem

The SPRY Switcher program is automatically installed with
WebScan. This program allows you to quickly switch from a network
communication method to a modem. During installation, the files
SWITCH.EXE and SWITCH.HLP are copied to this
directory:

\MCAFEE\WEBSCAN\BROWSE\BIN

In addition, the Switcher program is automatically configured.
However, if you install a new WINSOCK.DLL (the program that allows
applications to communicate on the Internet), you'll need
to set up the Switcher program. Please contact McAfee's
Customer Service if you need help with this configuration. Refer
to the contact information provided below for the phone number.

_________________
Program Anomalies

If you decide to uninstall WebScan, check for the existence of
the file WINSOCK.LAN in the following directory:

- In Windows 3.1 and 95, look in the \WINDOWS
- In Windows NT, look in the \SYSTEM32 under your Windows NT
  directory

If the file exists, rename it as follows:

WINSOCK.DLL
