Ouch! I think my machine has been infected by a virus, but it doesn't match the description of any I know about. Interferon reports that there isn't any virus that it knows about present, but it reports anomoly 103 on several system files (the ones I suspect may be infected by other evidence given below). Anomoly 103 isn't listed in the Interferon documentation, so question 1 is: does anybody know what anomoly 103 is? The symptoms are rather innocuous, but then again aren't almost all virus (viruses, viri, virium?) seemingly so? Symptom 1: In the system folder, the System, Finder, Multifinder, Scrapbook, and Clipboard files all have different icons than standard. They all appear similar to the uninfected icons, but the disk drive has the little open space on the right (which the normal icons dont) and there appears to be some kind of objects where the screen should be (looks almost like some books of various heights). Symptom 2: When switching from Multifinder to Finder, via resetting the startup option and issuing the "restart" menu command, the machine always hangs right after the "Welcome to Macintosh" message appears, and right before the Vaccine icon appears in the lower left corner. I have to power down or hit the restart button to get it going again, then it loads just fine. Symptom 3: Just for jollies, I rebuilt the desktop on my disk. When this completed, the icons for the Finder and the Clipboard file changed to a blank document page icon. The other system files described above still have the strange icons. There are extenuating circumstances here that point to the possibility that my newly repaired hard disk may have come from the factory repair shop with the virus already in the system file. When it returned from repair, it was loaded with the System 4.2, Finder 6.0 set, but all seemed well at the time. If anybody recognizes this virus, or has any clues as to how to proceed to track it down further (I can make my way around reasonably with Resedit and Macsnoop), please post here or respond by email. P.S. Vote Bill D. Catt for President. %%%%%%%%%%%%%%%%%%%%%%%%% From the Final Frontier %%%%%%%%%%%%%%%%%%%%%%%%% These are my opinions, of course. Why the hell would my company want them? Robert K.

This virus scare is getting a bit out of hand. Computer viruses are much like human viruses (e.g., AIDS); if you show care and practice "safe file transfer," then you are likely OK. Make sure you have vaccine, ensure backups are maintained on a timely basis, only bring programs onto your hard disk if you are confident they have been tested, and if you want to use a program which you're not sure of, boot off a floppy, dismount your hard disk, and run it off of floppy to check it out. If you do this, you have reasonable certainty that every little abnormal belch by your Mac isn't a viral attack. That aside, the very first thing anyone should do when they have a problem such as was described here (bootup problem, strange system behavior, etc), is boot off of a system floppy, delete the system from your hard disk system folder and replace it with a new one. Most often these problems occur because the system somehow became corrupted. Don't ask me how this happens, seems like this shouldn't be possible, but it does happen. phil...
