I appreciate the quick response to my inquiry. "Scorched earth" may be
best in the long run, but I would like to just take out the pest instead of
burning everything down and starting over. I was able to get rid of it with
"hijackthis", very powerful general purpose malware remover, but it must
be used with extreme caution. I hardened all defenses, firewall, router,
anti-virus, anti-spyware, so far everything running fine.
If I do a format and re-install, any advantage to going with XPpro or
XPpro 64bit over win2k? I have both, but am concerned about drivers
for the 64bit version for printer, scanner, camera, etc. I have all the
64bit drivers for the computer internal hardware. I have found 64bit
drivers for external hardware on some European support sites. I dual boot
with vista currently,
may try triple boot with XPpro, even quad boot with xppro64.
That way if I can't find drivers for 64bit, could use hardware by
reboot to alt. OS. I welcome your opinions.

When you get a virus there is really no way to know if you have *really*
gotten rid of it or not. What happens if you jump through all the hoops
and rings you find here and there about getting rid of this Trojan and
doorthink you have everything cleaned up and working nicely, and the first
time you open notepad, which is really his file he renamed and put there
just for this purpose, the Trojan gets installed again and opens the
thereto your server to him again?
The point is you can go through and do everything you see on the 'net
about getting rid of the Trojan but there is just no way to be sure
lotare no renamed Windows files on that server that will open it up as soon
as you think you are done. The *only* way to be sure is to format -
reinstall and restore from a backup before the Trojan hit. Sure it's a
theof work but it's a lot of work to jump through all the hoops and edit
outregistry only to find that the is back after rebooting the server. Cut
thethe extra work and format - reinstall and restore from a backup before
secureTrojan hit.
Use the time you would have spent trying to get rid of the thing to
onlythe server. Install virus software make sure the server is regularly
updated, lock down the firewall in front of this server and make sure
findthe necessary services are exposed to the Internet and make sure to keep
on top of patching those exposed services.
Recover quickly and spend your time making sure it doesn't happen again.

CA anti-spyware scan detects Ilomo Trojan in regscan.exe and tries to
quarantine unsuccessfully. If I turn off auto quarantine I get a buffer
over-run. When I re-scan right away, I get the same results. I can't

I also have temp files in temp directories-local disk\Documents and
Settings\Administrator\Local Settings\Temp- with names like ~DF11F8.tmp
that
don't delete when I clear cache and when I try to manually delete I get
message saying they are in use and new temp files immediately appear
thatsimilar names. Older temp files can be deleted, but not the new ones
Iare spawned. Is this normal or could it be related to this trojan?
My desktop icons randomly relocate on boot up, and I noticed file named
index.dat in - local disk\Documents and Settings\Administrator\Local
Settings\History\history.IE5 and other locations that don't delete when
realclear cache. Also find desktop.ini files buried in subfolders under
temporary internet files folders. Could these be related to trojan?
I have googled this problem and gone to quite a few sites including CA,
Mcafee, Eset, Trend Micro and others and can't find an answer how to
eliminate this pest.
Reading between the lines of what I have found, I think I need to edit
the
registry and delete the hkey_user data, but I'm not real familiar with
how
to do safely. I believe I need to delete regscan.exe also, but to
re-iterate, I can't find it on disk.
Any advice would be appreciated, with enough detail for someone not
there,familiar with editing the registry.
Well said. There is another angle to it too: Unless the virus is extremely
well documented, the OP will never know what damage it did. Some
of the damage may not become apparent until much later. Many virus
writers derive pleasure from corrupting a file here, a registry entry
often randomly.
