I was on my laptop today when I got a blue screen and my wallpaper changed to say that I have a critical warning. The exact desktop message reads: "YOUR SYSTEM IS INFECTED! System has been stopped due to a serious malfunction. Spyware activity has been detected. It is recommended to use spyware removal tool to prevent data loss. Do not use the computer before all spyware removed."

I managed to get rid of the desktop message (using AntiVir until the scan stopped for no apparent reason. The scan did not complete and I can't get it to scan again.) Under Desktop, the "critical_warning" file still appears in the list. The current wallpaper is the blue screen without the message written out above and I can't change it because this Desktop/Background page is locked up.

My homepage was changed (to google, oddly). I cannot access system restore, nor can I use Malewarebytes or other antivirus programs because I get a message that reads: "Windows cannot access the specified file. You may not have permissions to access the item." I have AntiVir PE Classic, which also won't fully run (it starts scanning, then stops).

Fortunately, I have a desktop so that I can post here and try to resolve the problem. Would someone please walk me through fixing this problem? Thank you very much!

Hi Teris, lets confirm things here. If I see evidence of malware, I will request this topic to be moved to the Am I Infected forum, since that is more suited.

ROOTREPEAL
-------------
We need to check for rootkits with RootRepeal
  • Download RootRepeal from the following location and save it to your desktop.
  • Extract RootRepeal.exe from the archive.
  • Open Posted Image on your desktop.
  • Click the Posted Image tab.
  • Click the Posted Image button.
  • Check all seven boxes: Posted Image
  • Push Ok
  • Check the box for your main system drive (Usually C:), and press Ok.
  • Allow RootRepeal to run a scan of your system. This may take some time.
  • Once the scan completes, push the Posted Image button. Save the log to your desktop, using a distinctive name, such as RootRepeal.txt. Include this report in your next reply, please.

regards, Elise

Hello, good news and bad news.

The good news is we identified the infection. This is a new rootkit infection, called Max++. The bad news is that it can only be fixed in the HJT-forum.

Therefore I would ask you to start a new topic and post a log if possible. Most likely you will not be able to post a log. In that case just post the RootRepeal log and mention you will not be able to produce a log.

Start a new thread HERE and include a link to this thread. Please make sure that you read the information about getting started before you start your thread.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient. Help is on the way!

regards, Elise

Thank you, Elise. I posted the new thread at: http://www.bleepingcomputer.com/forums/t/253143/max-rootkit-infection-help/.

I hope someone can help - this is all so confusing to me! Thanks again for your assistance. This is a wonderful resource.

Okay Teris, note that it can take up to a week to get a reply since there are many logs posted everyday!

And btw... I am by no means an administrator :thumbsup:

regards, Elise

Hello,

Now comes the hard part: waiting.

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, possibly over a week 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.
