AV Defs Updater for F-PROT for DOS 2.95

AV Defs Updater for F-PROT for DOS, an F-PROT updater / update utility, that renews your F-PROT for DOS antivirus definitions in the background and enables the automated creation of a set of emergency diskettes allowing you to perform a clean boot and check for viruses.

A quick procedure only for updating of the diskettes holding the antivirus definitions, or only the creation of a universal, general-purpose bootable DOS disk (thanks to the excellent FreeDOS Project) is provided. The DOS bootdisk can be created on ANY version of Windows. Online help (context-sensitive) is included. For installation instructions and considerations, please refer to the enclosed README. The installation or upgrade from an older version is easy and automatic.

Features of AV Defs Updater for F-PROT for DOS 2.95:

· Update of the antivirus definitions of F-PROT(r) for DOS(r) antivirus program (http://www.f-prot.com). The update frequency is user-customizable according to preference;
· Check for new releases of the F-PROT(r) for DOS(r) antivirus engine and facilitating its installation/update;
· Creation of a configurable set of emergency antivirus disks (compressed, hassle-free automatic usage, minimal set creation mode);
· Creation of a universally usable general-purpose FreeDOS(r) antivirus bootdisk (thanks to FreeDOS(r), F-PROT(r) for DOS(r) and XMSDSK!). Bootdisk is accelerated via RAM storage, which can be resized without rebooting thanks to XMSDSK.

What's New in AV Defs Updater for F-PROT for DOS 2.95:

· (Fixed) Upon the user specifying the directory where F-PROT is present/installed, the program now checks whether F-PROT is actually there (it checks for the presence of the main F-PROT executable, F-PROT.EXE). Before, it was checked only whether the specified directory actually existed. So, one could specify a directory that actually didn't have F-PROT installed. That could mislead users that their F-PROT had been updated whereas it actually hadn't been, despite a message by AV Defs Updater that F-PROT had been updated successfully.
Moreover, now the program not only checks for this upon the user specifying the F-PROT for DOS directory, but it also checks for it during each update (manual or automatic). In this way, the situation in which F-PROT may have been removed or moved away from the specified directory, but one still thinks that F-PROT is still actually being updated, can be avoided.
· (Fixed) When performing a manual update (via "Configuration and Manual Update"), the program now downloads F-PROT virus definition updates from the F-PROT update servers every time. The previous behaviour was that it would dowload them only if new F-PROT virus definition updates were available on the F-PROT update servers -- "new" meaning that they were newer than previously downloaded F-PROT updates by the same installation of AV Defs Updater. The old behaviour could cause a problem in the following situation: the user configures (specifies) an F-PROT directory in the program, then performs an update via the program. As expected, this procedure does update the F-PROT installation in the specified directory. However, if afterwards the user specifies a different directory and if at that time there is NOT a new update on the F-PROT servers, the F-PROT installation in the newly specified directory will not be actually updated, even though AV Defs Updater will report a successful update. The same problem will occur if the user does not specify a new F-PROT directory, but rather just replaces the F-PROT installation in the already specified directory with an outdated version. That is, this outdated version will not actually be updated by AV Defs Updater until a new update isn't released on the F-PROT update servers.
· (Fixed) A third-party program module used for checking digital signatures has been found not to have been well tested on Windows Vista. People have reported success running it under Vista, and our tests did not show problems with the functionality that we use from this module (which is fairly basic and often-used functionality, and thus the likelihood that it is actually just fine on Vista is considerable). The functionality gets used only when a new version of the program (AV Defs Updater) is released, i.e. not often. However, to avoid any possible problems, we are removing this module. Because of this, the way automatic updates are handled had to be changed, too.
We would be glad to know if you are using AV Defs Updater under Windows Vista. Please let us know by contacting support.
· (Fixed) In the installer of the program, errors were not detected and handled during the creation of window dialogs (not the informative message dialogs, but the window dialogs containing buttons and input fields). This could result in various errors, including corruption of memory. However, the errors could occur relatively rarely (for example, under low memory conditions). Actual problems haven't been reported by users.
