I think the two previous reports may have been false alarms.  I've  used
Fifth Generations Untouchable, Norton's Anti-Virus 2.1 (updated thru 
12/31/92), and Skulasson's F-Protect 2.06 on it and it comes out clean.

I've used both of the Norton resident utilities (NAV&.SYS and NAV_.SYS) and
can't get any sort of warning running any of the executables from 
PKZ204C.EXE.

According to Hoffman's VIRSUM (12/92), Maltese Amoeba installs in the high
end of available memory - if it's there, you should see a decrease in 
available RAM.  I've checked before/after running each of the new zip
executables & have seen no decrease.

Below follows the log from F-PROT 2.06:
