Extract Directly from Time Machine

Normally you use Time Machine to restore lost data in a file like this: within the Time Machine interface, you go back to the time the file was not yet messed up, and you restore it to replace the file you have now.

You can also elect to keep both, but the restored file takes the name and place of the current one. So, if you have made changes since the backup took place that you would like to keep, they are lost, or you have to mess around a bit to merge changes, rename files, and trash the unwanted one.

As an alternative, you can browse the Time Machine backup volume directly in the Finder like any normal disk, navigate through the chronological backup hierarchy, and find the file which contains the lost content.

Once you've found it, you can open it and the current version of the file side-by-side, and copy information from Time Machine's version of the file into the current one, without losing any content you put in it since the backup was made.

New HyperCard Virus

Send Article to a Friend

And TidBITS doesn't have it! I just checked all of the HyperCard stacks on my hard drive with the free "Find HyperVirus 1.3" stack from macclub benelux, the official Macintosh Users' Group of Holland (where the virus was first reported), Belgium, and Luxembourg, and it doesn't exist in any TidBITS stacks. Phew.

So what is this virus? It appears (note that I haven't seen a copy yet) that it is one of the first of the HyperCard script viruses, if not the first (I haven't seen the Dukakis virus either). I gather that the virus takes advantage of HyperCard's message passing to install itself in stacks whenever possible. No ill effects have been reported, although one of its scripts plays the song "Muss i denn zum Staedtele hinaus..." which might or might not be an ill effect, depending on your musical tastes. (Do you get the impression that I'm doing this all completely second and third hand and don't quite know what I'm talking about? Good, because that's what's happening.)

I haven't heard of any of the major virus checking programs other than SAM (and Virex, eventually) changing to find and delete this new virus, probably because it would be extremely difficult to detect and remove any HyperTalk script that could be construed as a virus. I recommend either using the definition below if you own SAM 3.0 (2.0 can't find it because it doesn't have a data definitions entry dialog) or finding the free Find HyperVirus 1.3 stack from macclub benelux at your local purveyor of free and useful software.

Paul Cozza, SAM's author, posted this virus definition for SAM 3.0.

Open the Data Definitions dialog in SAM 3.0 Virus Clinic by choosing "Add Definition (Data)" from the Definitions menu. Then enter the following information:

Virus Name: HC Virus
File Type: STAK
Search String pop-up menu: ASCII
Search String text field: if char 1 to 2 of LookAtDate <11

The string in the Search String text field above is an ASCII string. Blank areas between words are spaces. The string IS case sensitive.

As a guard against incorrect entry, SAM 3.0 has a "Check field" in the Definitions dialog boxes. If all of the above information is entered correctly, then your check field should be A0BD.
