                   Frequently Asked Questions about F/WIN
                   ======================================


I ALREADY HAVE A VIRUS SCANNER.  WHY USE F/WIN?

     a.   F/WIN uses heuristic detection for macro viruses that
          infect Microsoft Word documents.  That means it can
          find known and UNKNOWN macro viruses.

     b.   F/WIN can remove known and unknown macro viruses. A lot
          of the regular antivirus programs can only detect macro
          viruses and of course they only can remove KNOWN
          viruses.

     c.   F/WIN is a passive scanner.  That means you don't have
          to use Word templates to defend yourself against macro
          viruses.  These templates are no real safe protection,
          and of course, you will need Winword for using them.

     d.   F/WIN can detect the Windows 95 virus called <Boza>,
          as well as any future strains that use a similar
          infection scheme.

     e.   F/WIN can detect known and unknown viruses that infect
          Windows EXE files which use the <Winsurfer> or <Ph33r>
          infection scheme.

     f.   F/WIN is inexpensive, especially when considering the
          protection that it provides.



SHOULD I REPLACE MY EXISTING SCANNER WITH F/WIN?

     No.  F/WIN is a specialized scanner that is intended to
     supplement the one you currently have. By now, there are
     more than 8500 known viruses for DOS, but only about
     30 Windows specific viruses. You will need a normal DOS
     antivirus program, of course.  However, it's likely that
     the number of Windows viruses will increase in the future.

     Around April 1996, we will introduce a new DOS heuristic
     antivirus program called SUSPICIOUS.  It has been available
     in Germany for some time.  Like F/WIN, the scanner is purely
     heuristic in nature, and is able to detect known, as well
     as unknown DOS viruses.  Watch our web site for information
     as it becomes available.



DOES F/WIN DETECT MACRO VIRUSES IN OTHER SOFTWARE LIKE AMIPRO,
WORD PERFECT, ETC.?

     At this time it does not.  That is a feature we hope to add
     to it at a future date.  So far, F/WIN only detects macro
     viruses in Microsoft Word 6.0 and 7.0 documents.  The only
     known non-Winword macro virus AmiPro.Green_Stripe isn't
     reported in the wild.



HOW OFTEN WILL F/WIN BE UPDATED?

     Because of it's heuristic nature, F/WIN doesn't need regular
     updates like normal virus scanners.  Normally, updates will
     be released to provide bugfixes and will appear at least
     every two months.  Of course customers will be provided with
     a new version if they detect a virus which F/WIN missed.



HOW WILL I RECEIVE UPGRADES?

     Because the FWIN.KEY is valid for every new version, you just
     need to download the shareware version from your local BBS or
     FTP/WWW site and replace the FWIN.EXE file!  The latest
     shareware version of F/WIN is available at:

     http://www.entrepreneurs.net/fwin/index.htm (our temporary URL
              until the permanent one becomes active)
     http://www.fwin.com (our new URL sometime in mid-march, 1996)
     http://www.valleynet.com/~joe
     http://www.cyberbox.north.de (German site)

     The program is released as a ZIP archive and will have a
     file name like FWIN307E.ZIP (English version) and
     FWIN307G.ZIP (German version).
     


HOW SAFE IS F/WIN?  CAN IT DESTROY MY DOCUMENTS?

     The cleaning process has proven to be safe in our tests.
     But if for some reason it would damage your document, it
     makes a backup of it before attempting to remove the virus.

     The backup allows you to try a different method for cleaning
     or to recover the file if the cleaning process failed.
     Because F/WIN can't decode OLE2 objects like Microsoft Word
     documents with 100% accuracy, it's possible that it could
     destroy infected documents sometimes. If you encounter
     problems cleaning macro viruses, you could send us the files
     and we will clean them manually.  Also, F/WIN has two
     options to clean documents.  Both remove the virus reliable,
     but the second approach (Wipe macro names) needs less
     modifications and will work most likely in every case.



HOW QUICKLY WILL I GET A REPLY TO QUESTIONS?

     As we both aren't full-time virus researchers, we can't
     always respond at once.  We will check our accounts at
     least one time a day, so you will get answers within one or
     two days. We will do our best to get to you as quickly as
     possible.  If you are e-mailing us about a current virus
     emergency, please put "VIRUS EMERGENCY" in the SUBJECT line
     of your e-mail message.  Those messages will be given first
     priority.
