Local Area Virus Update
|
|
Bay Area - Sacramento
|
|
|
|
21 Sep, 1989
|
|
!WARNING! The Sacramento and Bay areas have been hit again by mutants
|
|
with computer's. Two seperate and distinct forms of virus bugs have been
|
|
encountered on BBS's here they are as follows:
|
|
|
|
1. A disk wiper, this one comes most commonly under the guise of
|
|
Optune10.???, Opimize etc. It's description says it is a disk opimizer
|
|
emulating Commando's DO.exe, SST, Spinrite. These programs de-fragment
|
|
files, change interleave and perform other useful and valuable
|
|
functions, without destroying data stored on the disk or drive. The
|
|
buggy clone(s) wipe out all data (just like Formatting). These files are
|
|
showing up on Bay area BBS's mostly.
|
|
|
|
2. The second bug is a true virus and has (as far as I know) to
|
|
date not been traced to a specific file(s). It's actions and environment
|
|
however has been isolated. It attaches to any program which sorts, such
|
|
as Xtree-Pro, Xtree, Vtree, DirTree, any File manager in otherwords. It
|
|
has also been caught on archivers and Communication programs i.e. Pro-
|
|
Comm+ and Zipper.
|
|
SYMPTOMS: In File managers it displaces a block of video at
|
|
location row 12 to 18, col 5 to 17. In Archivers, particularly *.PAK it
|
|
causes an error msg that PAK file can not be opened or is corrupted. In
|
|
the Comm programs it affects erratically the display, logons and
|
|
transfers, including external protocols.
|
|
Since it does not leave a message or access disk write functions
|
|
the virus and bug protect programs are useless. If you experience the
|
|
symptoms on your system the only way of detecting and this is 100%, is
|
|
to check the execute (*.exe,*.com) file sizes and compare them to KNOWN
|
|
clean versions. CHECK ALL EXECUTABLE FILES especially if you run
|
|
programs under another Windows, Xtree etc. This virus has cropped up
|
|
in the Sacramento area this month (September 1989).
