Detailed Description

This is a trojan, so it does not spread: it can not be considered a realistic threat. PKZ300 trojan is not widespread though the warning is.

CIAC has released an advisory on this hoax.

Please see http://hoaxbusters.ciac.org/HBMalCode.shtml#pkz300

The following is the true warning about PKZ300 from the PKWare web site:

 !!! PKZIP Trojan Horse Version - (Originally Posted May 1995) !!!

It has come to the attention of PKWARE that a fake version of PKZIP is being
distributed as PKZ300B.ZIP or PKZ300.ZIP. It is not an offical version from
PKWARE and it will attempt to erase your hard drive if run. It attempts to
perform a deletion of all the directories of your current drive. If you have
any information as to the creators of this trojan horse, PKWARE would be
extremely interested to hear from you. If you have any other questions about
this fake version, please e-mail support@pkware.com
