[comp.sys.mac.announce] SAM/MDEF C Announcement

D1660@AppleLink.Apple.COM (SoftPlus, Paul Cozza,PRT) (10/24/90)

 
For SAM 2.0 Users:
 
A new strain of the Garfield-virus (or MDEF-virus) has appeared which
can cause system crashes, error messages, or corrupted files once the
virus takes hold in your system.
 
If you have SAM 2 configured in Standard level or above, generally, it will
either issue messages

		  "Attempt to bypass SAM Intercept"

or messages stating 'that a suspicious change to or addition of an
MDEF resource' was being made (which specific messages are displayed
depends upon a number of factors, such as what machine is present, whether
MultiFinder is running, etc).  By preventing the addition or change of an
MDEF-resource Garfield is prevented from spreading.

To eliminate the original source of infection you should replace the
infected file with an original uninfected copy.   As an alternative,
you may obtain an update copy of SAM Virus Clinic from Symantec Corporation,
which repairs files infected with *THIS* strain of virus also.

You may add a virus definition to both SAM Intercept and Virus Clinic
which will cause to identify this strain by name.

 
The virus definition for this strain of Garfield is:
 
   Virus Name:  Garfield      (or MDEF)
 
Resource Type:  MDEF
  Resource ID:  0
Resource Size:  556
Search String:  4D4445464267487A005EA9AB       (hexadecimal)
