[comp.sys.amiga.misc] Begginer q's What's these Vectors thing? And what's trashing them?

yorkw@stable.ecn.purdue.edu (Willis F York) (03/21/91)

Well like a Good amiga user, i got the "Bigbrother" anti virus program.
and got it running.. but...

EVERY SECOND the thing pops up. I clear the memory, and it Pops up again!.

So obvisouly somthing's trashing somthing it shoulden't

So how do i find out what's doing it?

To be exact- it saya the following.

----------------------
ColdCapture - Offset   42 :$00000000  
CoolCapture - Offset   46 :$00000000 
KickMemPtr  - Offset  546 :$00000000
KickTagPtr  - Offset  550 :$00000000 
DoIO Vector - Offset -454 :$00fc06dc    <------- What are all these anyway? 

RadTask has not been found.
----------------------
This system has been modified.
Non reset virus.
^^^^^^^^^^^^^^    It's this line that has me Stumped....


Well i'm sure some other "begginers" would like to know more about this
topic.

I've never used Bigbrother, so I can only give you general information.

Yeah, it sounds like you've got a *really persistent* virus there!

>So how do i find out what's doing it?

I would advise you to get some anti-virus program that will actually tell
you *what virus you have*, not just that your vectors have been modified.
VirusX 4.01 does this, though it's a little out of date.  There's a more
recent one named Berserker which I think also identifies the beasties by
name.  This is what you need.

The Capture vectors and the KickPtrs have something to do with doing a
re-boot of your system.  (See below.)  DoIO I think is a library routine.

If you had a virus that took effect at boot time (reset time), it would've
modified one of the first four items on the list above.  You apparently
have something that acts at other times.  Like, I/O operations.

Now, one final thing:  Do you have any non-standard patches or utilities
active when you trigger this program?  Perhaps the change was made by
something other than a virus.  This is where it would be nice to have a
program that actually identified viruses by name.  (If Bigbrother is
*supposed* to do this (remember, I've never seen it), and it's not, either
you don't have a virus or you have a really new virus.)
