SCA Strain?

Supamax · 08 January 2009, 00:40

Hi,

I have two physical disks (Speed! and Mindshadow; I uploaded them to The Zone) with a strange bootblock.
X-Copy Professional v8.5 says they are infected with the "SCA Strain", but I compared their bootblock with a normal "bootable" bootblock and the difference is only 38 bytes.
Is this a real virus?? I doubt it!
If not, it's strange that the bootblock is "partially" infected (the first bytes)...

But, if it's not a virus, why do I have it on 2 different floppies/games?

Actually its just a standard install from a program called CLI-Manager. (had a look at the ADFs you put in the zone)

If you look at a byte display of the bootblock, the "CHW!" is what is has in common with an SCA, so thats what X-Copy must looks for. The rest is almost identical to whats in a standard 1.3 install

WOW! I wonder how did you discover it?

Do you remember all the bootblocks?

Yes, I saw the bootblock (with UltraEdit-32) and imagined it.
But what was bugging me was the strange fact it was only 38 bytes different from a normal bootblock

I thought it could be some form of super-compact SCA-type virus variant.

The reason i found this out is due to the fact I co-authoured with jasonver2.0 the Amiga Bootblock reader program on http://eab.abime.net/showthread.php?t=39978.
(sorry for the shameless plug!)

It interesting as the CLI-Manager program also installs an anti-virus which is now considered a virus (CLI-Manager virus).
