removing XP Antivirus 2012

I've found XP antivirus 2012 to be easier to remove than most other of the fakealert viruses.

With XP antivirus 2012, you can use control-alt-delete to end task. Then run an rkill. Then run quick malwarebytes scan and remove everything, but don't reboot. Then run a full malwarebytes scan. You may find that the virus restarts even after an rkill after 3 or 4 minutes. Just close the program again and run an rkill and let the quick malwarebytes scan to keep the virus from restarting. Then run the full scan to completely get rid of the virus.

using combofix in safe mode with command prompt

I was faced with a fakealert virus yesterday that existed in safe mode also, which made cleaning it very difficult. I used the command prompt method I used a couple weeks ago to clean it. Luckily, I was on a network - not sure I would have been able to do this on a stand alone computer. Here were my steps:

[on the virus affected machine]

boot into safe mode with networking

log in as a domain admin

create new local administrator (on the chance that I didn't know the local admin password)

[from another machine in the network that is not infected]

from another machine on the network logged in as a domain admin

go to \\10.0.0.54\c$ (affected computer drive)

create a new folder on the root of C called malware

download newest version of combofix and copy it to \\10.0.0.54\c$\malware

[on the virus affected machine]

reboot into safe mode with command prompt

log in as local administrator

run c:\malware\combofix.exe

You won't be able to install the recovery console, but in the two times I've tried this, it hasn't been a problem.

handling windows restore fakealert virus

Today, I dealt with another one of those fakealert viruses. This one was called windows restore. I had to take a couple minor extra steps. I booted to safe mode with networking. I found that the virus had removed the DNS servers (which had been statically set on this computer). I added those back and was then able to download malwarebytes. One thing that was super weird was that it had hidden all files and folders. I ran start -> run -> iexplore to start IE, but I also unhid all files.

After running malwarebytes and removing the virus, I found that all files were still hidden. I ran this from a DOS prompt to remedy that:

attrib *.* -s -h /s /d

And things were back to normal.

Of course I ran these instructions to clean the virus:

the anatomy of a fakealert infection

Over the last year, a new type of virus (malware) has become prevalant. The weird part is that antivirus vendors are way behind on detecting these new viruses. It seems new generations of these viruses change just enough to evade detection. This post will show you what it typically looks like when you are infected with one of these viruses - called fakealert viruses.

It starts by visiting an infected site. These don't necessarily need to be inappropriate sites. You can visit an infected site from a regular innocuous google search.

You start by getting a pop-up like this:



For some viruses, hitting OK might infect you - or it might be hitting any of the buttons in the pages that follow. What you're seeing here is a web site pop-up with words on it. It could just as easily be telling you the plot of last night's CSI: Miami. A web page can display anything as you will soon see. In this case, it just happens to be misleading text. The virus can't just infect you - it needs a little help from you in order to run a script.

If you hit ok, you often get something like the screen below. Again, it looks like something your computer is telling you - but it's just a web page. It could be a spoiler for Dancing with the Stars, but it's just an image and text that someone chose to put on there. Nothing is really scanning.




If you try to close the browser, it won't let you. No matter what you try, you get something like this:
















And then it will often try to run/download a file to further infect you.



Another example of what you might see:


-----

So what is the answer? You've found your way to a web page that you can tell is trying to infect you - but it's hard/impossible to close your browser (the example here is Firefox - but Internet Explorer is vulnerable as well).

The answer is to close your browser with Windows Task Manager before you can be infected. Hit control-alt-delete and the start the Task Manager. Find your browser on the applications tab (either Internet Explorer or Firefox) and hit end task. This will close your browser without the annoyances and get rid of the potential infection before you are infected (presuming you didn't interact with virus/malware in the web page).



So that's pretty much it. That's what you should be looking for and the best way to avoid infection if you come across these types of viruses/malware. If you find yourself infected, you can use the tools listed here to disinfect your computer.

UPDATE - Symantec talks about fakealert viruses here:

Still no improvement on the handling of these types of malware. Very lame.

malware removal tools

The fakealert malware viruses are everywhere. I've managed to rid most of them with just two tools:

rkill - to terminate the running processes
Malwarebytes - to remove the infections

For just about every fakealert virus, I put rkill.com and mbam.exe (links above) on a flash drive and then run rkill.com on the infected computer. Then I run Malwarebytes full scan and then remove whatever it suggests.

The other day, I came across a machine with different symptoms - just in time debugging kept coming up over and over again. I fixed it with combofix, but here's also another suggested tool that I didn't have to use:

Combofix
Dr. Web CureIt

So far, I've fixed every infection I've found using some combination of these tools. I wonder when the antivirus vendors will ever get a hold on this. It's been over a year that these types of viruses have been in the wild.

winsock failed to initialize

When cleaning up a fakealert virus the other day on an XP machine, I had successfully cleaned it, but none of the network interfaces could get an IP address. My only real clue was a simple dialog box that said "winsock failed to initialize"

Luckily, I found this utility:

I ran it, and it fixed my problem very easily.
