Hi,
I was just browsing imdb.com with my dad and we suddenly had a virus or viruses rapidly begin to take action. We first noticed a popup appear with only the text like "??????". Before I could finish saying don't click the Ok button to my dad, he had clicked it. From that point on we have not clicked buttons on any pop ups. After that we started seeing all kinds of fake alerts about viruses. A window came up that appeared to be from Windows and was scanning for viruses. There are 2 tray icons that keep showing balloons about security risks or detected viruses. There is a very legitimate Security Center Alert asking if we want to enable windows firewall protection against net-worm.win32.dipnet.d, Backdoor.Win32.Kbotal, Trojan-Downloader.JS.Multi.a. The Keep Blocking and Unblock buttons are disabled. We immediately tried to restart in safe mode because it seemed the virus(es) were running out of control despite having McAfee installed. We were unable to start in safe mode. Every time it got to mup.sys we got a bsod, I think it was PAGE_FAULT_IN_NONPAGED_AREA. So we were forced to restart in normal mode. We installed (when trying to install spybot we were first redirected to a fake spybot page that wanted us to enter username and password info...) and ran Spybot and it found and removed the following:

Fraud.Sysgaurd
-C:\Program Files\txatfb\sysguard.exe
-Some registry keys pointing to that exe

Win32.KillAV-KQ
-Class ID: AFD4AD01-58C1-47DB-A404-FBE00A6C5486

Microsoft.WindowsSecurityCenter_disabled
-Registry key to start wscswvc

Opachki.ru
-C:\DOCUME~1\DAVIDS~1\ntuser.dll
-C:\WINDOWS\system32\calc.dll
-Some registry keys pointing to both of these

Virtumonde
~.exe

After removing these we tried to restart in safe mode again but continued to get the bsod. When we restarted, we got a bunch of popups about rundll being unable to find ntuser.dll and calc.dll so whatever was running those is still on the computer. My dad is running a mcafee scan right now which I assume won't fix the problem. He's continuing to get the fake security popups and tray icons/balloons. It has also placed shortcuts to porn sites with little porn icons on the desktop a couple times. Should I use combofix? Can anyone help? I feel bad, cause he just re-installed his OS 2 weeks ago and I was the one telling him to go to imdb when it apparently was installed from an add.

I think I have removed a lot of what was installed by using Spybot, process explorer and spyware doctor to identify bad files, then removing exes, dlls, temporary files and registry keys myself. These included a program named active security that appeared to be a valid security program. I manually uninstalled this because I assumed uninstalling it through add/remove programs would just make things worse because it provided its own "uninstaller". There was also wow64____.exe (I can't remember what the blank was) in the Temp folder, proquota.exe in system32\wbem, batmeter16.dll from the windows directory which appeared as "iexplorer" in task manager, and several others. I still have no way of knowing what else might be lingering without some help so please don't disregard my original post, but I have at least gotten rid of the popups (for now). Currently the remaining symptoms are when IExplorer starts up with 3 homepages (3 seperate tabs), it loads for a second and then shuts down. Second, starting in safe mode will still not work. We get a 1x50 PAGE_FAULT_IN_NONPAGED_AREA BSOD when it gets to mup.sys. I know this can be indicative of bad memory but there have been no other problems. Could these "viruses" have caused this and can it be repaired?

Hooked by "PCTCore.sys" at address 0xb9ecae22

You have a rootkit infection
Just deleting PCTCore.sys does not get rid of it


Now that you were successful in creating those two logs you need to post them in our HJT forum There they will help you with the removal through some custom scripts and programs that we cannot run here in this forum

First, try to run a DDS / HJT log as outlined in our preparation guide:
http://www.bleepingcomputer.com/forums/t/34773/preparation-guide-for-use-before-using-malware-removal-tools-and-requesting-help/

If it won't run, don't worry, just give a brief description and tell them that these logs were all you could get to run successfully

Post them here:
http://www.bleepingcomputer.com/forums/f/22/virus-trojan-spyware-and-malware-removal-logs/

The HJT team is extremely busy, so be patient and good luck

Hello xr280xr,

I see your father has now posted a log concerning this issue here: http://www.bleepingcomputer.com/forums/t/267505/ddsscr-log/ I have pasted in the three logs that were posted in this topic into that topic.

Please note that only your father will be able to respond to the topic in the HiJack This forum.

Now that you have posted a log, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days, up to two weeks perhaps less, to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
