Hey all,

Working on my girlfriend's dad's (there's a tongue-twister) IBM laptop - he has the fake Windows Security Alert virus described at http://www.bleepingcomputer.com/virus-remo...ssentials-alert.

I've gone through that guide, as well as a few others related to this specific piece of malware, to no avail. The malware is blocking almost any exe file from running, including taskmgr and regedit - it doesn't even allow the other window to open, it just moves its own window to the top and refuses to close. No Firefox, no IE, no nothing.

Every link to every renamed rkill iteration has not worked for me - the window opens and closes instantly, returning to the fake antivirus screen. exeHelper stays open and appears to run fine, but does not cause the malware to close. When I run ComboFix, the blue bar pops up and fills up next to the cougar logo, but then disappears and pops back to the fake antivirus.

(Sorry for running ComboFix unrequested - just figured I'd try everything myself before I came crying for help. I've built two PCs so I'd like to think that I wouldn't have bricked someone's laptop armed with only ComboFix.)

Despite the program not closing, I decided to try the Malwarebytes program - which removed a couple of other pesky bits of malware he was dealing with, but did nothing to the fake Windows Security Alert.

Not sure if I'll be able to post logs at the moment - the laptop currently doesn't have a working web browser, is not equipped with a CD burner, and neither myself nor my girlfriend's dad have a flash drive. (I've been burning CD after CD of rkill/exeHelper/Malwarebytes/Combofix from his desktop computer downstairs and running them upstairs to get the programs onto his laptop.)

His OS, by the way, is Windows XP Pro SP2.

If you need any other info just holler - otherwise, thanks in advance for the help.

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.

Please refrain from running tools or applying updates other than those we suggest while we are cleaning up your computer. The reason for this is so we know what is going on with the machine at any time. Some programs can interfere with others and hamper the recovery process. Please also continue to work with me until I give you the all clear. Even if your computer appears to act better, you may still be infected.

Even if you have already provided information about your PC, we need a new log to see what has changed since you originally posted your problem.

Once we start working together, please reply back within 3 days or this thread may be closed so we can help others who are waiting.

We need to create an OTL report,
  • Please download OTL from this link.
  • Save it to your desktop.
  • Double click on the icon on your desktop.
  • Click the "Scan All Users" checkbox.
  • Under the Custom Scan box paste this in:

    netsvcs

  • Click the Quick Scan button.
  • The scan should take a few minutes.
  • Please copy and paste both logs in your reply.

We also need a new log from the GMER anti-rootkit scanner. Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice

Then create another GMER log and post it as an attachment to the reply where you post your new OTL log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


In your reply, please post both OTL logs and the GMER log.

PS> If you're there but can't run the scans due to the system state, let me know that as well.


If I don't respond within 2 days, please feel free to PM me.
Please don't ask for help via PM. The forums are there for a reason. Please post in the forums so others may benefit as well.
