This is my first time posting, so I'm sorry if I've done something wrong...

Yesterday evening, my mother was browsing the web on our other netbook - identical to this one. She clicked on a link on Google and was taken to an address, which as best I can discern from her description, was then forwarded to a page that started giving her all of the "This computer is in danger of malware!!" messages. I immediately took over and canceled all of the download/open/run acceptance windows and got the browser window with all of the fake alerts to close.

I went online, searched, and to the best of my knowledge, determined it was "Cyber Security", and not one of the other scarewares. I navigated to this page from this computer:

http://www.bleepingcomputer.com/virus-remo...-cyber-security

And followed the instructions. When I downloaded and ran rkill, in only took a few moments, and when it finished it told me it only terminated itself (rkill.exe). So my first question is, is that normal? That it goes that fast and only terminates itself, I mean?

I also downloaded, renamed, and ran Process Explorer. There were no processes that I didn't recognize, and the only one that was marked with a lock was the Carbonite Preinstaller that came preloaded on both of these computers. :thumbsup: As annoying as it is.

I had already downloaded MBAM, and it was setting on the desktop, so I updated it and ran a full scan. It found only one infection - in the Temp folder - for Trojan.FakeAlert. It successfully quarantined and removed it.

After that had finished up, I checked the processes one more time, and restarted the computer. As soon as it restarted - as normal - I ran rkill, checked the Process Explorer, ran another MBAM, ran Spybot S&D, ran a full Avast! scan, and then ran ANOTHER MBAM. Everything turned up normal, with no infections - except for Spybot, which turned back the same tracking cookies as always, from our regular browsing.

Truthfully, I haven't used that computer today, but I was wondering if anyone can tell me if there's anything else I can do to ensure that I've cleaned it as much as possible before I work with it, and also if rkill terminating itself is normal, as I said before.

We're running on Windows XP, SP2; and the infection seems to have started in IE, if that means anything. Thanks!

Hello and welcome. All that is fine. When running other malware scans you should disable Spybot's Teatimer,if you have it running. Here's how if needed.
TeaTimer works by preventing ANY changes to the system. It will attempt to undo any fixes we run, because it blocks these fixes from running.

In order to safeguard your system from problems that can be brought on by a half finished fix, we need to disable TeaTimer. We can reenable it when we're done if you like.
  • Open SpyBot Search and Destroy by going to Start -> All Programs -> Spybot Search and Destroy -> Spybot Search and Destroy.
  • If prompted with a legal dialog, accept the warning.
  • Click Posted Image and then on "Advanced Mode"
    Posted Image
  • You may be presented with a warning dialog. If so, press Posted Image
  • Click on Posted Image
  • Click on Posted Image
  • Uncheck this checkbox:
    Posted Image
  • Close/Exit Spybot Search and Destroy

Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..

Then press enter on your keyboard to boot into Safe Mode

Double-click ATF-Cleaner.exe to run the program.

Thank you, boopme, for your reply and instructions! Sorry it took me so long to get this taken care of...We discovered yesterday evening that our Jeep suddenly will not start, so the computer took back burner.

I followed your directions, and have since restarted as per your instructions. SUPER found no threats, but here's the log just the same:

SUPERAntiSpyware Scan Log

Application Version : 4.34.1000

Memory items scanned : 224

Registry items scanned : 6267
Registry threats detected : 0
File items scanned : 16853
File threats detected : 0

The computer has been starting normally the entire time, even since our initial "infection". We'll try browsing around the web and whatnot here in a bit. In the meantime, is there anything else I should try doing?

I DO have one question though. In the "Scanner Options" of SUPER, the following were already checked:

-Ignore files larger than 4MB
-Ignore non-executable files
-Scan only known file types (.exe, .com, .dll, etc.)
-Resolve links/shortcuts during scan (.lnk)
-Scan alternate data streams
-Use Kernel direct file access
-Use Kernel direct registry access
-Use direct disk access

And this one single option was unchecked:

-Ignore system restore/volume information on ME/XP

Are these the proper settings to be running the scan under? It not, what changes should I make, and should I run it again in safe mode after doing so?

Thanks again!

We feell these to be the most efficient settings for SAS. Malware and Antivirus tools cannot clean System Restore files. This can be a large area so no sense wasting time scanning it.
If all is good on here now then We will do this, this will empty the infections in System Restore safely.

Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista and Windows 7 users can refer to these links: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.
