- Sub: WDEF Virus - updated info
-
- An item with the subject "Warning: New Virus Outbreak" was recently mailed to
- UG$ by USER.GROUPS. Unfortunately, the info in it regarding the WDEF Mac virus
- is already somewhat outdated, and an item or two is incorrect.
-
- I have uploaded announcements for John Norstad's Disinfectant v. 1.5 and Chris
- Johnson's GateKeeper Aid (v. 1.0) to the User Groups bulletin board here on
- AppleLink. You are urged to refer to those messages for more detailed info
- about WDEF and these two freeware products that combat the WDEF virus.
-
- I have also noted that an updated version (v. 3.1.1) of Jeff Shulman's
- excellent shareware VirusDetective DA is available in the third party product
- demo section on AppleLink.
-
- Please note that the WDEF virus specifically subverts the protection offered by
- current versions of Vaccine, GateKeeper and commercial anti-virus utilities
- (including Symantec's SAM Intercept 1.10, and HJC's Virex INIT 1.12). Even if
- they are properly installed and running, it will elude these utilities and
- manage to infect your disks.
-
- Following is a brief summary of utilities and methods that can be used to find
- and/or remove the WDEF virus from the (invisible) Desktop file on an infected
- disk:
-
- 1) Disinfectant 1.5, by John Norstad, (note v. 1.5 is now current) finds both
- strains of WDEF and will remove both from the Desktop file. Disinfectant
- continues to be able to find and remove all other known Mac viruses.
-
- 2) The VirusDetective DA, by Jeff Shulman, (current version 3.1.1) comes
- configured to scan for all Mac viruses and also many simple clones. Although
- it should not be used to "disinfect" files of most viruses, it it safe to use
- it to remove a WDEF infection from the Desktop file.
-
- 3) GateKeeper Aid, by Chris Johnson (just released in v. 1.0) is an INIT that
- will automatically find/remove the WDEF infection upon start-up and also as any
- disk is mounted on your Mac. The use of the INIT does _not_ require that one
- use GateKeeper. GateKeeper Aid is the easiest and most "idiot-proof" WDEF
- protection yet available, and every Mac user should add it to their System
- Folder.
-
- 4) Rebuilding the Desktop file by holding down the option and command keys as a
- disk is mounted removes WDEF. The problem is that all "Get Info" comments are
- lost in doing this, and you have to do this for any and all disks as they are
- mounted, else you could get reinfected!
-
- 5) ResEdit can be used to remove the WDEF resource from the Disktop file. _Any_
- WDEF resource found in the Disktop file is abnormal and should be deleted. (DO
- NOT delete WDEF resources from other files, however. WDEF is a legitimate
- resource name in many files. The WDEF virus only attacks the Desktop file.)
-
- 5) The Eradicate INIT that was written in Europe to remove the WDEF virus is
- buggy and should not be used. A rewrite is in the works and ought to be
- released in the near future.
-
- That is the state of the art relative to WDEF scanning/removal at this moment.
- The commercial anti-viral utilities are being updated to combat WDEF also, and
- may be available by the time you read this. Apparently Apple's own Virus Rx is
- also being updated and will likely be released soon.
