Hit or not?

I'm using WinXP SP2 with the latest patches (except SP3) installed. While

browsing the internet using a limited account, IE7 pops up the following

message; exactly as it appears (I bet the bad guys meant to say CRASHES

instead of CREAHES):

 

----------------------------------------------------------

ATTENTION! If your computer is struck by the spyware, you could suffer data

loss, erratic PC behaviour, PC freezes and creahes.

 

Detect and remove viruses before they damage your computer!

Antivirus 2009 will perform a 100% FREE and quick scan of your computer for

Viruses, Spyware and Adware.

 

Do you want to install Antivirus 2009 to scan your computer for malware now?

(Recommended)

----------------------------------------------------------

 

I know Antivirus 2009 is a rogue antivirus. It must NOT be allowed to

install. Avast 4.8 Home Edition remains quiet. It doesn't warn me about the

danger that's about to hit my PC. Btw, I was browsing http://encarta.msn.com

and 1 other site which is bestbuy.com. Makes me wonder why I got AV2009

pop-up from those 2 sites. Does the pop-up really come from those sites? I

have no clue.

 

Anyway, when I saw the pop-up, I did NOT click any button (OK, Cancel

button). I did NOT click the red X button on the top right corner of that

pop-up window either. My guess is it doesn't matter what button gets

clicked, it'll proceed with the installation. Instead of responding, I

pulled up Task Manager and End Task IExplore.exe process.

 

Here are my questions:

 

Based on the above info, is my PC infected?

 

Is it possible to infect a PC with Antivirus 200whatever when the user does

not respond to the question but kill the process instead?

Also unknown. The infection process might be an "improvement" over what

we've heard of recently.

 

The first thing we ask is that you download, update, and run the

freeware version of MBAM.

 

<http://www.malwarebytes.org/mbam/program/mbam-setup.exe>

 

Once you've accomplished that, post a simple reply (no cut & paste with

the output report) and we'll go on from there.

 

Best wishes and good luck to you Jack.

Probably with some malware but possibly not seriously as yet. IOW, it is

probably still possible to get the machine clean fairly easily.

Depends on what else the user is infected with and what vulnerabilities s/he

has such as obsolete versions of Java, Adobe Reader, operating system

patches (which means you, BTW), etc.

 

I would go through the following general malware removal steps, not skipping

the prep work and then follow the removal instructions for AV 2009 at

either BleepingComputer or Malwarebytes.

In my opinion, you are probably not infected. If "probably" is good

enough for you (and it shouldn't be), then there is no need to check

further. The tools offered by other posters aren't that hard to use so

why not increase your confidence by running them.

 

You did good by ending the process with task manager.

 

Yes, some use the "x" button as another "yes" button.

 

Not sure why your antimalware wouldn't alert, perhaps it would

have alerted had you downloaded the executable. This is a good

example of the correct role of an antivirus program - it should be

used as a backstop for when you fail to compute safely. It

should be your goal to prevent it from having to act on your

behalf.

 

Good job!

I feel the same way too. With all the defensive actions (limited user

account, up to date patches, End Task the process etc) on my part, I'd be

really impressed (or confused :-)) if this malware infects my PC.

 

Btw, I did a full scan with Avast after posting the first message. No

infections found. I'll get the tool from malwarebytes later just for the

heck of it. I have no important data in this laptop anyway.

Thanks. I was once a programmer. I believe we can put the same codes in OK,

Cancel, X button when those events are triggered. That is why I chose to end

task instead of clicking.

 

What I still don't understand is how the heck do I get AV2009 pop-up while

browsing 2 websites that appear to be safe (encarta.msn.com and

bestbuy.com). All of a sudden, there is a 3rd IE7 tab, with the following

info:

 

- IE address bar shows h y y p://antivirus - computer- scan.

com/2009/1/en/free scan.php?id=77011801

- IE status bar and the 3rd tab shows h y y p://windowsxp - privacy.

net/?id=12193338844

 

(I changed the URL to prevent accidental click or copy/paste)

Those sites are malicious according to http://trustedsource.org/

Are you saying that by the time we see a pop-up message, we're all infected

before we respond to the message? If that's the case, why do malware writers

bother asking us if we want to scan our PC? Why don't they just install it

silently?

I have Acrobat Reader 8.1.2 but I wasn't using it at the time AV2009 warning

popped up. Btw, I know Acrobat Reader 8.1.2 has a security vulnerability and

I also know that Acrobat Reader 8.1.3 and Acrobat Reader 9 are available but

I haven't updated my Acrobat Reader yet. I don't have Java. My OS is WinXP

SP2 with patches up to Nov 2008. I believe it is the same as having XP SP3 +

latest patches.

I changed my mind. Instead of installing removal tools, I manually searched

for AV2009 infection. Not one of the following exists:

 

%UserProfile%\Desktop\Antivirus 2009.lnk

%UserProfile%\Application Data\Microsoft\Internet Explorer\Quick

Launch\Antivirus 2009.lnk

%UserProfile%\Local Settings\Temporary Internet

Files\Content.IE5\S96PZM7V\winsrc[1].dll

%UserProfile%\Start Menu\Antivirus 2009

%UserProfile%\Start Menu\Antivirus 2009\Antivirus 2009.lnk

%UserProfile%\Start Menu\Antivirus 2009\Uninstall Antivirus 2009.lnk

c:\Program Files\Antivirus 2009

c:\Program Files\Antivirus 2009\av2009.exe

c:\WINDOWS\system32\ieupdates.exe

c:\WINDOWS\system32\scui.cpl

c:\WINDOWS\system32\winsrc.dll

 

My Avast antivirus doesn't warn me about anything other than doing its

regular updates. Zonealarm doesn't ask me if some process that I've never

heard of want to access the internet or the trusted zone. Everything else

looks normal, no system slow down etc. I'm confident that I've dodged a

bullet.

I'm saying that there is no way for me to know the state of your computer

before you got the popup message from AV 2009. All I can surmise from your

posts is that your machine is probably not fully patched since you don't

have XP SP3. Since you haven't kept your operating system updated, there is

a logical possibility that you haven't kept other programs updated that can

be vectors for infection (Flash, Adobe Reader, Java, MS Office, etc.).

Therefore it would be wise to be proactive and do scanning to be sure the

machine is clean.

 

I've had clients who got the popups for AV 2009 (or variants) and who

quickly closed out of the messages (one woman just shut her machine off

with the power button!) and they were fortunate: the malware didn't

install. I've had other clients who went to a webpage with a malicious

banner ad (for ex.) which took advantage of their older, vulnerable Java

and they got severely infected with multiple trojans.

 

Some malware does install silently and some doesn't because it can't. Of

course malware writers would prefer not to bother with the social

engineering and just install their cr p silently if they could! There tend

to be far less "drive-by" malware installs on Vista than on XP. For a good

understanding of malware installs, a great place to start is with some of

the many articles that Ben Edelman has written.

Diversity. If other vectors of ingress fail, ask the user to do something.

These programs are written for diverse targets, similar to the way web

designers may need to write for a diverse set of browsers.

The mere presence of vulnerable software might be enough - if the malware

can access a vulnerable program (and run it) it could use that to escalate.

It

may not be necessary that you have the vulnerable program already running

when the malware attempts to infest your system.

 

I'm speaking generally - not about this malware specifically.

Advertising content allowed by the "safe" websites, or compromised otherwise

"safe" websites. You never really know a place is "safe" - the best you can

do

is to keep your system as up-to-date with patches for both the system and

the

application software.

 

They could even (in some cases) cause your browser to go to the "safe" site

after visiting their malicious site (DNS poisoning or similar) - so you

must

consider the administration of your system to include your router.

Additional malware could easily hide those things from you, which is

why the others hinted at the possibility that a newer version of that

malware may do things unknown as yet to be associated with it.

 

Rootkits are all the rage these days...

Nor would it if a sophisticated malware were doing just that.

 

I'm not a proponent of outbound filtering of that type anyway because it

assumes malware is already running on the system, and yet ignores that

fact when touting its usefulness.

....as long as you're confident - after all, it's your choice.
