[comp.sys.mac] Virus Question

zark@csd4.csd.uwm.edu (Steven M Kosloske) (05/04/90)

I have just recently bought a Macintosh Plus, and after loading up all the
software I had onto my Hard Drive I ran Disenfectant and found what it
thinks is a virus.  The error it gave me reads:

   Desktop
### File infected by WDEF A.

There is no file called Desktop on my drive, does this mean the desktop
itself is infected by this virus?  It also mentions that the file is open
so it cannot clear the virus.  What can I do about this?

None of my other files seem to be infected.

THanks in advance,

Steven -
Every initialized Macintosh Disk or Diskette has (or should have) a 
Desktop file on it.  The file is not, however, normally visible on your system. 
You might see that it's there by using a disk utility such as SUM, or 
FastBack, but otherwise you might never know of its existance.

If  Disinfectant reports you have a WDEF A virus in your Desktop file, you 
need to get a clean (read uninfected) System Diskette with a copy of your favorite de-virusing software (Disinfectant will do nicely), Boot from that diskette, then run use the de-virusing software to clean up your hard drive.  

Be prepared to reload system software and applications as de-virusing your 
files will occasionally damage their structure.

Hope this helps.  Good luck.

	Am I correct in my impression that you have not discovered the
	documentation in Disinfectant?  Click on the About-button ...

	what the original author should have done (and didn't do) was
	to read the documentation that comes built-in with Disinfectant.
	nothing is more frustrating than to see people not make an effort
	to find the answers to their questions themselves before posting,
	especially for the people who bring you FreeWare programs such
	as Disinfectant, and who went to great length to provide documen-
	tation too ...

Disinfectant can clean the desktop file if MultiFinder is turned off.
Hold down the command key while booting, and then run Disinfectant.
