THIS IS HOW TO GET RID OF VX2-ABETTERINTERNET, etc...

A

I struggled with this for a week, and finally figured out
how~!!!

VX2 seems to come in many variations, but they all seem
similar. The one I had planted atleast 2 files on my
computer:

msguard.dll
msg118.dll

These files cannot be deleted because they are in use.

The program also made a registry key:

hkeylocalmachine\software\microsoft\windows
nt\currentversion\winlogon\notify\guardian\.....

There was also another key that was the same except
instead of \notify\ it was \notify_disabled\

The way I got rid of this bug was to go into regedit and
right-click on the "guardian" subkeys and change the
permissions for the system service to disabled. Note that
there is a switch to disable that holds permissions from
previous subkeys, and I switched that off.

Then I rebooted. I went into safe-mode dos prompt. I dont
think it is necessary, since that never helped in the
past, but I wanted to be SURE as little programs run as
possible. At the dos prompt, I deleted these two
programs, windows\system32\msguard.dll and msg118.dll (I
have seen reports that there are sometimes a msg117.dll
too -- if you have it delete it!) I wasnt able to do that
before, but since the key that calls these programs is
disabled from running, the files are nolonger in use.

Then I re-booted and ran my favorite anti-spyware program,
and it ran out of virtual memory while trying to delete!
The problem was that it couldnt access the key it was
trying to delete, so it just kept trying! I went back
into the registry and re-enabled the keys and re-ran the
spyware and voila! Its gone!!!!!!!! I have seen other
people do things that worked once for one person, and
maybe this was my lucky break, but this is what worked for
me so maybe it will work for you!!!!!

Good work, and thanks for posting the explanation. I have cleaned this
successfully, with Microsoft Antispyware on a Windows 2000 VPC, without
resorting to safe mode. However--you've accurately described why we often
ask folks who are having trouble cleaning a system to try scanning in safe
mode with Microsoft Antispyware--there are definitely times when it is
unable to clean in normal mode, and can clean effectively in safe mode.

Another way to kill the guardian if you know its name
(reglite

http://www.resplendence.com/download

can usually see it even if regedit can't) may be a
freeware program called apm.exe (Advanced Process
Manipulator) from DiamondCS.

I had a similar winlogon notify infection on a friend's PC
and that was the only way I found to stop it. I tried
messing with the permissions first but did something wrong
and managed to annoy windows so much that it used the
last known good on the next reboot and told me it was
recovering from a serious error. By the way, if working
on a Win2K system you have to use regedt32 and press on
the Security button on the tool bar to get to
Permissions.) I ran apm.exe and it brought up a list of
active processes. I opened Explorer and there were about
5 instances of the malware. I selected one and told it to
stop it and a little box with an OK button came up.
Clicked on it and another box came up. After about 5
clicks the malware really was stopped. I still couldn't
delete the file but I could rename it. And after a reboot
I was able to remove it.

Thanks - I've been meaning to look into APM since you last posted about
it--looks useful.

And since this piece of malware has an autoupdate "feature" it is likely to
change payloads over time. VX2 "The Spyware that Behaves like a Virus" :)
