| This was a real problem to clean up because it kept reinfecting itself and
| it consists of more than a dozen different files and registry entries plus
| some assorted popups.
|
| Some hints. (and I'm not a techie so pardon the level of this discussion):
|
| The bad stuff is all in the Windows/System32 file and in the registry.
|
| The various *.exe files (ishost, ismini, isnotify etc.) need to be deleted
| manually in safe mode
|
| A group of *.dll files that keep changing names seem to carry the Trojans
| and keep restoring them to the computer. These dll's can be identified by
| sorting system32 by date; they are the most recent. Some can be easily
| deleted; some cannot.
|
| There are also a few files that write stuff to the registry (again, most
| recent) but keep coming back.
|
| Two programs: drweb-cureit and vundofix were able to delete the dll files
| after reboot. ProcessExplorer (from Windows) (right click on explorer - go
| to threads) can kill some of the active dll's and allow deletion.
|
| I ran Spybot many times because it was helpful in finding some of the bad
| files and registry entries that kept returning. Searching the registry for
| bar888 found a bunch more. I used several other virus scanning programs
| as well. smitfraudfix and smitrem may have been helpful; I ran them both
| but am not sure what they did. The hijackthis log also showed some files to
| be deleted that would not otherwise been obvious.
|
| Semantec's web site gave TWO registry deletions for the returning and ever
| present and mssmgr. .
|
| You probably need to turn off restore points. I tried restoring the system
| and it didn't work anyway.
|
| Based on something I read, I put a clean copy of wininit.exe into system32.
|
| There was a time that the computer would only boot in safe mode.
|
| This was really a process of reducing the number of bad things almost one at
| a time until the computer began to function again. At the end, it took
| Defender and NAV about four passes each to get rid of the final pop-ups and
| smaller issues.
|
| Fortunately, I have a laptop and wireless network so that the various AV and
| other files could be downloaded and moved (safe mode with networking) to the
| infected
| computer.
|
| In summary: unless you really know what you are doing (I don't), it will
| take the better part of a day; lots of web research (google); many
| downloads, scans and reboots; and a lot of frustration to get rid of this
| thing.
|
| I appreciate everybody's help and feedback.

That's interesting becauase VundoFix is geared towards the Vundo Trojan/Virtumonde Adware
family of malware which is separate from the SmitFraud family of malware which icludes the
FakeAlert and Zlob Trojans.
Your posting "...various *.exe files (ishost, ismini, isnotify etc.)..." is indicative of
the ZLob Trojan family files.
Maybe you had both a SmitFraud and Vundo infection. I don't know but that uis most likely.
The tools mentioned are the *best* for removing SmitFraud and generate log files so you can
SEE and READ what they did.

Maybe what you had was a Broad-Spectrum infection. As such you should have used the
following as well..
* Ad-aware SE v1.06
http://www.lavasoft.de/
http://www.lavasoftusa.com/
http://www.lavasoft.de/ms/index.htm
* SpyBot Search and Destroy v1.4
http://security.kolla.de/
http://www.safer-networking.org/microsoft.en.html
* SuperAntiSpyware

I also want to stress that prevention is better than cure and prevention is performed by
practicing Safe Hex.
