- Major changes between version 2.x and 3.x
-
- This note is intended for users that are familiar with F-PROT version 2,
- and want a short summary of the major changes.
-
- 1) The program combines the macro-virus scanning ability of F-MACROW
- with F-PROT in one program.
-
- 2) The scanning technology itself has been improved, and the program now
- detects significantly more viruses than version 2 did. Where F-PROT
- 2.28 detected just over 10,000 different viruses, version 3.01
- detects nearly 17,000 DOS/Windows viruses, over 1,000 Trojans and
- over 2,500 Word and Excel viruses, for a total of over 20,500.
-
- 3) The program is now almost entirely data-driven, which means that
- adding detection and disinfection of new viruses will usually not
- require any changes to the program itself. Therefore, it will
- usually be sufficient just to update the SIGN.DEF and MACRO.DEF
- files, which also means that we will be able to provide updates
- much more frequently than before.
-
- 4) Version 2 was a 16-bit program, compiled with Borland's C compiler,
- but version 3.x is a 32-bit DOS-extender program, compiled with
- Watcom C and uses the CauseWay DOS extender.
-
- 5) Version 3.x requires DOS 3.0 (or later) and at least a 80386 with
- 4MB of memory, where the previous version would work on a 8088,
- with 512K memory, running DOS 2. We know that a small minority of
- our former users will not be able to use version 3 for this reason,
- but unfortunately there is nothing we can do about this.
-
- 6) The VIRSTOP program has been discontinued, and further updates will
- not be provided. We consider the technology it used outdated, as it
- provides no protection against polymorphic viruses or macro viruses,
- which are probably the biggest problem today.
-
- For Windows '95 users we offer a VxD replacement, named F-StopW.
- This program (unlike the old VIRSTOP) should have the same detection
- capabilities as the main scanner in F-PROT itself.
-
- 7) F-PROT 3.x is able to scan inside .ZIP and .ARJ archives, without
- having to rely on an external program.
-
- 8) The heuristics in version 3 are being redesigned, with the primary
- goal of redesigning the false alarm rate. This work is still in
- progress, but the current heuristics are now enabled by default.
-
- 9) Before starting a scan, the program now automatically scans MBRs
- and boot sectors on the hard disk.
-
- 10) User-defined strings are no longer supported, as the program does
- not use "strings" as such any more.
-
- 11) The list of known viruses is no longer included in the form of
- VIRLIST.LIS, but it can be produced by the program itself by
- giving the following command:
-
- F-PROT /VIRLIS > VIRLIST.LIS
-
- 12) The virus information section of version 2 was badly outdated and
- has been removed. It will be replaced by a different program in
- the future.
