- Version 1.1 of FLU_SHOT+ has a few enhancements:
-
- 1. If you use the '-B' switch when you first run FLU_SHOT+,
- the machines BIOS will be used instead of direct screen
- writes. Useful for machines which are less than IBM-PC
- compatible. Or those people still running CGA's who don't
- like snow. It's a little slow. For the CGA users: you
- ever think of how nice it would be to see an unblurred
- screen? EGA's aren;t that expensive anymore....
-
- 2. I neglected to remove some comments, and there was a hole
- in FLU_SHOT+ V1.0 that a worm could have exploited. The
- hole has been patched securely....
-
- 3. An additional option in the FLUSHOT.DAT file:
- X=<ambigious_filename>
- allows a matching program to "turn off" the triggering of
- FLU_SHOT+ for the entire duration of its run. This could
- leave a security hole if you're not careful....so be careful!
- Do not use an ambigious directory: running a trojan from there
- would not trigger FLU_SHOT+. I use it for programs like
- FORMAT, Norton Utilities and that kind of stuff. I'm very
- careful when using it, though. And you should be, too!
-
- 4. The in-memory protection table is now checksummed so that
- worms can't change the files you're attempting to protect.

- Version 1.2 of FLU_SHOT+ has a few enhancements:
-
- 1. A new option, '-I<num>' has been added. This allows you to
- determine the frequency, in 1/18 seconds, of how often the CMOS
- Check (if enabled) and the Protection Table Check are going to
- run. The lower the number, the higher your protection, but
- the more impact it will have on system operations: they'll
- be a little slower. The default is set to one second.
-
- 2. Some complaints from those having FSP in their AUTOEXEC.BAT and
- having a line of the the form R=\AUTOEXEC.BAT. FSP was protecting
- the AUTOEXEC.BAT file (an intended option), but the boot sequence
- was causing people to have to hit a 'G' to continue with their
- boot. I've installed a '-S<num>', where <num> represents how many
- 1/18 seconds to sleep before activating the R= option.
- The default is set to 10 seconds. It will also immediately
- expire on the first key hit.
-
- 3. Because CMOS and Prot Table checks are done via the timer tick
- in Version 1.2, there is no need for the counter to be associated
- with the CMOS flag any longer. As such, '-C' is the full option
- to turn on CMOS checking.

- Version 1.4 of FLU_SHOT+ has a few enhancements:
-
- 1. I've skipped Version 1.3 - something about the number having
- bad luck and all.
-
- 2. A major bug, due to programmer stupidity, has been fixed. Alas,
- this bug actually could cause some damage to your disk.
-
- 3. The X= switch works better now - it was ignored on Direct Disk
- Writes
-
- 4. Some of the error messages have been made a bit clearer.
-
- 5. Complaints from some of the users have caused me to increase the
- size of the checksum buffer internal to FLU_SHOT+. This has the
- sad result of increasing the TSR size of the program itself -- but
- I consider it a reasonable increase for speeding up the checksumming
- of files.
-
- 6. If a file to be checksummed could not be found at startup time,
- the previous files checksum was displayed -- this has been fixed.
-
- 7. Certain holes in FLU_SHOT's security system have been patched.
-
- 8. The size of the FLUSHOT.DAT buffer has also been increased to allow
- users to specify more files to be checksummed and/or protected.
