This is a nasty worm distributed via msn messenger. It does not allow
any of the anti virus programmes to run and it shuts down regedit and
many other program windows.

The Norton Antivirus Serflog removal tool for A and C versions does not
work as I think they refer to an earlier version of this nasty virus.
There is information on the new version in the above link but their
recovery suggestions relies on using regedit which the worm totally
prohibits (it also does not allow access to their site or Norton
Antivirus, I tried searching the host file to no avail). Does any one
have any ideas please how to get rid of this nasty programme? There is
nothing on Microsoft or Norton Antivirus about this latest threat.

I even tried downloading some shareware registry editors but the worm
shuts down those programs as well.
 
This is the message it puts up but only on certain days of the month
(19th, 26th etc):
'Hello LARISSA, are you out there? You ****ing n00b!!!!!!!!
LARISSA you're my bitch! I own your ass you ****ing loser!
'-S-K-Y-'-D-E-V-I-L-'
Greets,
N+E+T+D+E+V+I+L'

If anyone has any ideas as to how remove this thing, I would be
grateful, as mentioned earlier the Norton Serflog removal tool runs
(which is an achievement itself) but says the computer is not affected
by Serflog as this is a new variant I think. The machine has windows XP
SP2, with norton anti-virus and Windown antispware beta. All recently
updated.

I am trying the trendmicro product now but from what I hear it won't be
without its own side effects. This new variant of the worm does not
allow you to turn off system restore. It completely removes the tab
from my computer properties. I wish I could find this guy and shoot the
bastard on the spot.

Much obliged for your suggestion anyway.

If you can not turn off system restore before cleaning, try after
running Sysclean and cleaning your system,restart and go right back
into safe mode and then try to turn off system restore and if able to,
re scan again after restarting your computer with sysclean in safe
mode.
 
What about HijackThis!

Did you try turning off all unnecessary services in safe mode, and
launch the anti-malware apps from there?

Well Stinger did not work. I give up. I don't understand why sysclean
did not work, perhaps I did not set up the logon script correctly, does
anyone have any advice on how to make sure the logon script runs
properly?

Removing Malware Entries from the HOSTS File

Deleting malware entries from the HOSTS file removes all malware-made
changes on host name association.

1. Open the following file using a text editor (such as NOTEPAD):
%System%\drivers\etc\HOSTS
(Note: %System% is the Windows system folder, which is usually
C:\Windows\System on Windows 95, 98, and ME, C:\WINNT\System32 on
Windows NT and 2000, and C:\Windows\System32 on Windows XP.)
2. Delete the following entries:
* avp.com
* ca.com
* customer.symantec.com
* dispatch.mcafee.com
* download.mcafee.com
* f-secure.com
* grisoft.com
* kaspersky-labs.com

Thanks for your help but that was the first thing I had tried, he has
done something to hide his tracks as the "hosts" file accessible in
windows\system32\drivers\etc is fine! It has none of the sites listed.
I need to figure out how to make the logon script rquired by trend
micro to work, I can't believe they provide the tool incomplete.

Download the scan engine and pattern file from a different computer if
you have one.
If you don't have another computer I will send the files to you.
You have to make a folder on the hard drive and unzip the files into
it.

Have you tried using the various removal tools/sysclean while in Safe Mode?

I'd be able to have a look at what it does in a safe environment and
possibly give you removal instructions if you are able to send me a copy of
the virus by email. That is if you a) have it b) can send it and c) trust a
stranger with a dangerous piece of software :-) Let me know and I'll give
you a different address if you can/want to send me a copy.

Adam Piggott.

It was bound to happen sooner or later, seems someone had forgotten how
important a clean boot is to recovering from malware and offered up an
OS making it more difficult than it has to be.
 
That is very kind of you but I don't know how to. I have already
deleted the PIF file, if it has restored itself I will send it. I have
tried safe mode, debug mode....... The problem is that this new variant
hides the autoexec file and does not allow access to it from other
machines on the network, it seems to ignore it as well in safe mode or
normal mode, hence my earlier question about logon scripts. I tried
running it as a command, windows issues a window saying the proogram is
not from a known publisher should it be run but before you can answer
the virus memory resident program closes tthe window.

They are not useless. They just have limitations.
HiJackThis will be beaten if the malware-writers spot a new avenue of attack
that is not in its checklist.

You can remove it manally but you have to be super-vigilant in Safe Mode in
making sure all entry points are deleted. Leave even one and an executable
copy and it will reinstall itself.

Do you have an unzipping utility? It would save some email download time
if I zipped the stuff before sending it.
 
Thanks for your help, here is the status so far:
I ran trendmicro's sysclean (finally, and with difficulty, their
instructions which depends on a logon script did not work), the virus
is present even in safe mode. Sysclean did not work either. So none of
the tools, trendmicro, or norton's serflong removal or stinger work.

The instructions below and any manual recovery are not really helpful
as the virus takes total control of things like taskmanager, regedit
etc. I am going to look at using another compupter perhaps to access
the registry. For example the system restore tab is hidden from my
computer propoerties dialogue (in any mode, including safe mode).

my e-mail is a a z a r _ t @ h o t m a i l . c o m (remove the spaces
otherwise google scrambles the e-mail).

Go here,

http://securityresponse.symantec.com/avcenter/venc/data/w32.serflog.removal.tool.html

but use another computer, download the file fixSflog.exe.

The virus will not prevent you loading this on an infected
machine via a floppy.

Just double click to run. I did it in normal mode, repeated
in safe mode
in that order. It was cleaned out in normal mode, in safe
mode it found
nothing.

All instructions are given on the page above.You do not have
to be running
Norton AV etc, the pc I cleaned up user AVG.
