- General Description:
-
- Scanning, resident scanning and disinfection capabilities. The informational
- utilities present in the earlier (1.xx) versions have been replaced by
- heuristic analysis scanning. Change detection and operation restricting
- utilities have been removed and not replaced.
-
-
- Comparison of features and specifications
-
-
-
- User Friendliness
-
- Installation
-
- Installation is now added as a feature in the main program. Manual
- installation is still an option, and is likely the one most used by those
- familiar with the program. Since the program is shareware, and since
- installation is little more than copying of files, unless VIRSTOP is installed,
- it is unlikely to present any problems.
-
- In the automated installation, VIRSTOP is installed to be invoked from
- AUTOEXEC.BAT. Those wishing to invoke it from CONFIG.SYS must do the
- installation manually.
-
- Ease of use
-
- Except for resident scanning, F-PROT is now invoked from a single program. The
- user, by default, is presented with a graphical interface, but command line
- switches are an option for those wanting more speed, or a standard invocation
- for a large group of users.
-
- There is no "help" key, but the options are fairly simple, and explained in
- text boxes where necessary.
-
- Help systems
-
- There is no help per se, although a listing of command line switches is
- available.
-
- Compatibility
-
- F-PROT consistently maintains the highest ratings in all independent tests of
- scanning of known viral programs, including my own. In terms of disinfection
- capability, only Alan Solomon's Anti-Virus Toolkit has similar ratings.
-
- Because of an external language file, F-PROT is available in at least six
- languages, and can be readily translated into others.
-
- Sporadically, F-PROT will fail to scan large drives which are divided into
- multiple partitions. This problem is fairly rare. It has been addressed, but
- it is unknown as to the success in all situations.
-
- There have been ongoing reports of problems installing the VIRSTOP resident
- program under MS-DOS 5.0. Moving VIRSTOP in the boot sequence, particularly
- with respect to memory managers, generally is successful in alleviating the
- problem.
-
- The heuristic analysis portion of the program occasionally generates a "false
- positive" alert about a program that is not, in fact, infected. This is to be
- expected from this type of scanning, and the incidence is much reduced from
- when this function was first included with the program. The heuristic analysis
- feature has been generally effective in identifying new and "unknown" viral
- strains, but is not perfect. (Perfection is, of course, inherently
- unattainable in this type of program.) Indeed, the documentation for this
- feature states that it is still to be considered experimental, and is very
- conservative in its claims. Programs known to cause false positives are
- listed.
-
- F-PROT may be run under Windows, but is not a Windows program. This is planned
- to be addressed in future, as are improvements for VIRSTOP to make it run with
- Windows, and to check files as they are copied, to check floppy disks as
- accessed, and to use EMS memory.
-
- Company Stability
-
- Fridrik Skulason has left the university, and is concentrating full time on the
- research and development of this product. His company now employs four staff
- in addition to himself. F-PROT is being included in commercial programs, and a
- commercial version of F-PROT will be announced shortly. frisk has, however,
- committed to continuing to support the shareware version.
-
- Company Support
-
- Fridrik Skulason is available through the Internet, and replies to queries can
- be expected within a week or less. Recently the program has become much more
- popular with the general public, and numerous people have requested his Fidonet
- address. Unfortunately, frisk is not active on either Fidonet or VirNet.
-
- Documentation
-
- Being shareware, the package has no printed documentation. The text files
- included with the programs are very clear and thorough, and provide an
- excellent primer on virus functions and protection, as it relates to scanning
- and disinfection. The large single USAGE.TXT file has been broken into smaller
- "chapter" files, which allows for quicker access to a particular function or
- feature.
-
- As some of the other virus detection and prevention capabilities have been
- dropped from the package, so the very excellent discussions of the different
- types of antiviral software, and their strengths and weaknesses, have been
- dropped from the documentation. It is recommended that interested parties
- obtain old (1.xx) versions of F-PROT for this material.
-
- The virus information files previously contained in separate text files have
- been included as a virus information feature within the main program.
-
- Hardware Requirements
-
- No special hardware is required.
-
- Performance
-
- During testing, FPROT has consistently identified more viri than the "current
- release" of any other product. FPROT is generally slower at scanning because
- of the multiple signatures being used to check for each virus, but is not the
- slowest scanner tested.
-
- The user is in control of FPROT at all times, with the exception that
- VIRSTOP will not allow the boot sequence to continue in the case of a boot
- sector infection at startup.
-
- FPROT, in two years of my testing, has not given a false positive alarm on any
- normal program, nor has it interfered with any normal program operation.
-
- The various functions and utilities that have been dropped from the 2.xx
- version programs still have significant value. Serious virus researchers and
- consultants would do well to obtain copies of older (1.xx) versions. These
- have been retained, and are available, at better antiviral source sites.
-
- Local Support
-
- Since FPROT is shareware, there are no local dealers to obtain support from.
- FPROT has fewer users in North America than SCAN, and so local help may be
- harder to obtain, but the documentation should make up any deficiencies.
-
- For users in Europe, FPROT is available in places as a commercially distributed
- product.
-
- Support Requirements
-
- Very little support should be needed for this program. On occasion assistance
- my be needed in disinfection, or in positively identifying a new viral strain,
- but no product tested deals with this situation better than F-PROT.
-
- General Notes
-
- Because of its "shareware" distribution, FPROT is best compared against John
- McAfee's SCAN program. F-PROT is kept up to date with regular additions to the
- signature file, and constant improvements to the program. SCAN versions are
- released at approximately the same frequency as FPROT, but in two and a half
- years FPROT releases consistently identified more viri, and with greater
- accuracy than did the "same level" releases of SCAN. SCAN also needs to
- release far more "bug fix" versions than does F-PROT. Fridrik Skulason
- publishes fewer signatures of new viri on the VIRUS-L (Usenet comp.virus)
- distribution lists than he used to, but some others are supplying appropriate
- signature strings in his format. F-PROT is significantly cheaper than the SCAN
- suite as well, and is complete in one package, although the SCAN suite in total
- now offers some edge in utility.
-
- I am personally sorry to see that the former utilities are not included in the
- current package. However, it is unarguably simpler for novice users to install
- and use the newer package, free from the confusion of the multiplicity of files
- contained in the previous version.
