Re: STOP THIS! (was: Internet Virus)

Hello all.

Here's a double case when a "seal" of authenticity could be
important on the internet: In the first instance, a virus disguising itself
as a "virus alert" might be a particularly bold and effective strategy. I
hope we don't see that. In the second case, a benign "text-based" virus
which replicates by convincing the reader of its urgency and causing that
reader to re-post it, might stay around for years, lurking in corners and
waiting for a new population to infect. Apparently, we have just seen that.
Either the "Internet Virus" post is correct and current, or the following
"STOP THIS" post is correct and current. ISN'T CYBERSPACE WONDERFUL?

: 1) This is a stupid, overwriting Trojan, not a virus

: 2) It was NOT discovered on the Internet...but rather on some obscure

: Now for a more detailed description of what happens:

: 1) WARPCOM II finds the COMMAND.COM used to boot up the computer.
: 2) Deletes it, even if it is read-only.
: 3) Creates another that is the same size with the same creation/modification

: WARPCOM II makes no screen writes so it can be easily concealed in a
