This thing won't stay deleted...(logs included)

[Ariane]

I have spent several days researching on your excellent site, downloaded lots of your handy tools, got rid of lots of bad stuff I didn't know I had.

And for this much thanks. (And a donation when I work out how!)

But I can't get rid of the original problem

I have had one of the backdoor worms. It manifests as a SCVHOST.EXE file in WINDOWS/SYSTEMS. (I know that SVC = good, SCV = bad!!) I can't delete it vie Windows Explorer because it's in use. I can't see it when using control-alt-delete (this is Windows 98) so can't stop it running. I can delete it in safe mode and know which 2 registry entries to delete. All is OK in safe mode. But when I restart out of safe mode - there it all is again!!!!

What am I doing wrong? Or is it a problem with my Windows 98 settings?

Here's some logs, run after norton antivirus scan, cwshredder, adaware and spybot search and destroy.

The first is from safe mode:

Reboot into safe mode by following instructions here: http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406
then as some of the files or folders you need to delete may be hidden do this:
Open Windows Explorer & Go to Tools > Folder Options. Click on the View tab and make sure that "Show hidden files and folders" is checked. Also uncheck "Hide protected operating system files" and untick "hide extensions for known file types" . Now click "Apply to all folders"
Click "Apply" then "OK"

Delete these files
C:\WINDOWS\SYSTEM\runonce.exe
C:\WINDOWS\SYSTEM\REGCPM32.EXE
C:\WINDOWS\SYSTEM\SCVHOST.EXE

then
Reboot normally &

as something ahs damaged and reemoved part of your norton antivirus, reinstall that asap
for now
Run an online antivirus check from at least one and preferably 2 of the following sites
http://security.symantec.com/default.asp?
http://housecall.trendmicro.com/
http://www.pandasoftware.com/activescan/
http://www.ravantivirus.com/scan/
http://www3.ca.com/virusinfo/

then
Download and unzip or install these programs/applications if you haven't already got them. If you have them, then make sure they are updated and configured as described

Spybot - Search & Destroy from http://security.kolla.de
AdAware 6 from http://www.lavasoft.de/support/download

Run Sybot S&D

After installing, first press Online, press search for updates, then tick the updates it finds, then press download updates. Beside the download button is a little down pointed arrow, select one of the servers listed. If it doesn't work or you get an error message then try a different server

Next, close all Internet Explorer and OE windows, press 'Check for Problems', and have SpyBot remove all it finds that is marked in RED.

then reboot &

Run ADAWARE

Before you scan with AdAware, check for updates of the reference file by using the "webupdate".
the current ref file should read at least 01R296 16.04.2004 or a higher number/later date

Then ........

Make sure the following settings are made and on -------"ON=GREEN"
From main window :Click "Start" then " Activate in-depth scan"

then......

click "Use custom scanning options>Customize" and have these options on: "Scan within archives" ,"Scan active processes","Scan registry", "Deep scan registry" ,"Scan my IE Favorites for banned URL" and "Scan my host-files"

then.........

go to settings(the gear on top of AdAware)>Tweak>Scanning engine and tick "Unload recognized processes during scanning" ...........then........"Cleaning engine" and "Let windows remove files in use at next reboot"

then...... click "proceed" to save your settings.

Now to scan it´s just to click the "Scan" button.

When scan is finished, mark everything for removal and get rid of it. (Right-click the window and choose"select all" from the drop down menu) then press next and then say yes to the prompt, do you want to remove all these entries.

reboot again

then post a new hijackthis log to check what is left

Thank you for your extensive reply - I'll get right on it.
