McAfee WebScan v1.0
Release Notes - November 1995
Thank you for your purchase of McAfee WebScan. As with all
McAfee products, we would like to have your comments. If you
have not already done so, please complete and return the
registration card and include your suggestions or comments.
If you downloaded the product from a McAfee online service,
you need to complete the registration form provided in the
file README.WRI. If you bought WebScan from a store, a
registration card and license agreement is included in the box.
Please be aware that this version of WebScan is the McAfee
domestic release for the United States and Canada. The
Internet access method uses a domestic, 800 number to
establish the online connection. Note that the international
version of WebScan will soon be available.

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.

download while the first is being scanned, an error message is displayed.
