YES, during the patch Tuesday updates. The malicious software removal tool.
It's a barebones thing that only looks for certain malware. Not nearly what
you need.

I'm sorry if part of this question is vague. My ex-gf was annoyed at
her computer and impatient with me and I got a discription in dribs
and drabs, and incompletely.

She seems to have a virus. When she started winXPSP3, she got a green
shield and a message that she may have a virus, and it gave 4 or 5
suggestions of what to do. I don't know what the other suggestions
were. She chose to run some anti-virus that it suggested, and hten
changed her mind and called me.

That was the virus.

us she has is AVG, and I suggested she do a full scan
with that, but it wouldn't start. When she clicks on AVG icon in
systray it says: "application can not be executed if avgui.exe is
infected"

Restarting gave the same first message. This time she told me about
the green shield and that the message was in an IE box.

Should she have let that anti-virus run to completion?

No, it was the virus. It was a scam.

At first I thought it was one of the web scan/scams, but maybe it's
good???

Nope, it was a scam.
Last night I dl'd the latest copy of Bit Defender Rescue Disk, and it
is far different from last December's version. I'm going to give her
the CD at work today, but it would be simpler if the suggested scan
was a good thing to run.

You can try running this, as this is good at removing the odd piece
of "rogue" malware. The free version is what you'd be downloading,
which is used for extermination rather than constant monitoring.

http://en.wikipedia.org/wiki/Malwarebytes

http://www.malwarebytes.org/

http://majorgeeks.com/download.php?det=5756 Apr29,2010 version 1.46

The main problem with using a program like that, is the malware may
prevent the tool from being started. You can try renaming the file,
to something like "surprise.exe" and run it. If that doesn't work,
you'll have to check some of the anti-malware sites for tools
that can temporarily stop the malware, until you can get MBAM started.

As far as I know, MBAM claims to work best in regular boot mode.
It isn't supposed to work quite as well in "Safe Mode", but you
can try that as well, if you're not making any progress. You can be
assured, that any "rogue AV" program, is well equipped to deal with
all the usual workarounds, so removing it won't exactly be easy.

If the "name" of the rogue software is printed on the screen
of the affected computer, you can use a search engine to search
for more information on it.

Too late now & she shouldn't have clicked on ANYTHING in the pop-up, not
even the X to close it!

The suggested "anti-virus" was the infection! It's a "rogue," quite

Run Malwarebytes Antimalware, with the latest definition files, using a
full scan. Run the scan once, delete anything you don't know to be good,
then reboot and immediately run it again, doing another full scan.

Not if it is already infected by malware.

Thanks to all of you. Yes, the screen must have been part of the

finished and it says she has 4 viruses. I'm going there now to look

will work.

The problem with this particular scam or malware is that it roots itself
into your registry. You should find a free program called "Hijack This" to
identify start up entries that keep whatever was installed to her machine
alive. There is also a rare file called "ComboFix" that can find and remove
a number of issues.

Those 2 free programs I mentioned have been able to help me remove
ad/malware completely from my PC after infection.

Good luck.

Thanks. I found Hijack This, which looks very good, and I"m going to
look for CombofFix.

I still started another thread to give my progress, such as it is.
She can download email, virus definitinon, and according to MS, HTTPS
and FTP.

Only HTTP eludes her!

IMPORTANT : ComboFix is extremely powerful , You should not run
ComboFix.exe unless you are asked to by a trained helper

Wait a second. If he's helping me, who's in charge!

But seriously, the descriptions give a lot of warnings, but also say
this:

"ComboFix also displays a report that can be used by trained helpers
to remove malware that is not automatically removed by the program.

Please note that running this program without supervision can cause
your computer to not operate correctly. Therefore only run this
program at the request of an experienced helper."

Yet the progrma removes things (malware) automatically!!!! I'm sort
of reckless but that scares me.

You can do anything you want... as long as you have backups.

If you haven't prepared for a "meltdown" while you're curing
this malware, you could end up in a awful mess.

No matter who wrote the anti-malware tool, such a tool can
quarantine or delete enough files, to cause the OS to fail to
boot the next time. If you took the system offline and did
a backup when you first started working on the machine, then
you have options if things go wrong.

For example, I've heard of tools, that quarantine infected files,
but they're placed on a temporary ramdisk. If you shut down
such a tool, the ramdisk disappears with it, and if you need to
put any of those files back, they're gone.

If it's your own machine, then you know how valuable the
setup and files are. You might not need a backup image for
that. If you're working on someone else's machine, then more
care should be taken.

Well, right now the problem is not mine but my ex-gf's machine and she
doesn't have backups. I had to urge her for 2+ years to start using
an antivirus. In fact all those 230 viruses that I report in my next
thread that she found from 2003 and 2004 were probably from the time
when she didn't use antivirus.

Ha ha. I don't know if I'm the only one, but I told that story here
last December. It was BitDefender Rescue Disk. They never replied to
me when I wrote to tell them about this problem but they have very
much changed how the program works and also expanded what it does.

It no longer has quarantine at all. Now it only has no change,
delete, disinfect, and rename.

You know, even last December they deleted or disinfected, and maybe
even renamed files on the hard drive. If they could do that, they
could have written the quarantine file to the same drive, instead of
the ramdisk. I wonder why they didn't think of that.

Exactly. But what gets me is not that the risk is so high -- as you
say, it's not, if one has backups -- but that they post all these
warnings and then, at the same time, go in the other direction by
removing things automatically. It seems self-contradictory.

It's not just the money. I would hate to have a child growing up in a

But we're still friends. We do favors for each other. In this case,
I'll probably learn a lot about computers, and I'd rather learn on

In your first post in this thread, you told us she had AVG installed which
"wouldn't start" but you didn't tell us she'd be running without an AV app
for 2+ years.

That's true, I didn't say that, but fwiw, that period ended about 5
years ago.

I'll send her your post and, it is to be hoped, she'll do all or at
least some of these things.

Thanks.
 
Not wise. Actions have consequences!
Click to expand...

For sure.

So far, she seems to have gotten off easy this time. I'll try to use
this problem as a motivation for her to start doing backups. In
truth, at least in the past, it didnt' matter much if she had no
backups because she had no user data of any remaining importance. She
doesn't or at least didn't engage in important email correspondence.
Etc.


Anyhow, the problem may be solved. Whatever it is started when she
went to www.letmewatchthis.com , to download a tv show or movie. She
had done this before with no trouble, but this time a screen came up
in AVG warning her that she might have a virus and to do a scan. She
was suspicious, but not enough and she ran the "scan" for a little bit
before stopping it. The website has been hacked, is that a fair
conclusion? They'll fix it eventually??

Yesterday, after I scanned with BitDefender Rescue disk and got rid of
6- year old emails with never-opened viruses, I scanned with AVG and
found a trojan and an registry entry pointing to it.

Is it possible this is a new trojan/virus that wasn't in the AVG list
on Friday (when she got infected) and was in the list on Saturday when
AVG found it.


The final problem seems to have been the FFox proxy settings.

[Almost the same text follows as in the later thread:]
My friend called me this morning. After I left, AVG finished scanning
everything yesterday and didn't find anything more.

But she got a different, new message from Firefox, something about
"can't find the proxy". So she knew I'd be sleeping that early and
she called another friend and he had her go to:
Firefox/Options/Advanced/Network/[Connection] Settings and she was set
for Use System Proxy Settings. (So am I.) He had her change to No
Proxy, and now her FF works. As far as she has noticed, everything
works.

She hasn't checked IE yet, but neither did I yesterday. Maybe it
worked after I used AVG to remove the trojan. But it seems the virus
changed soemthiing in the "System Proxy Settings" so that they no
longer work. What in practice, before the virus, the difference
between them and "no proxy" was, I don't know.

Is there some way to find the System Proxy Settings and change them
back to their proper values?

Thank you all for the help, and even the criticism in the next thread.
