I have been trying for several days to get my systems cleaned, but when I reboot to regular mode I get a command prompt window that keeps opening over and over with a an error window that reads "windows\system32\cmd.com is not a valid win 32 app. It prevents me from doing anything with my computer. I do have a guest account that I can run some tasks on. When I try to f8 and go to safe mode, the only options I get are for my drives. From what I have read here, I need to get to my desktop before I can get started on all of my other problems. Any ideas?

I am running Panda Software's "Panda Safe CD" right now, but it seems stuck on a few files (just keeps showing the same files over and over in the scan line"

Hello boatsandbeach,

I see that you have several topics open. Are these all for the same computer? In order to avoid confusion for everyone, we can only allow one topic per issue per computer.

I see that you have a HiJack This topic here: http://www.bleepingcomputer.com/forums/t/191951/i-just-cant-get-rid-of-it-something-keeps-starting-a-new-windowssystem32cmdcom-virus/ with the same title as this topic. I'm assuming that is the same computer.

I also see that you have another topic in the Am I Infected forum here: http://www.bleepingcomputer.com/forums/topic191772.html Is this the same computer?

I also see that you have a topic in the XP forum here: http://www.bleepingcomputer.com/forums/topic191930.html

Please note that it is important to include all the information in ONE topic; otherwise, we are working half-blind.

Please let me know in a reply to this thread which topics are for this computer. In the meantime, I am closing the other topics to avoid confusion and so you do not end up with conflicting advice.

Hi Orange Blossom,

Yes, all of those topics are for the same computer.

Summary:
My main problem seems to be when I start in normal mode at the exact time explorer starts, i get a command prompt window that repeatedly opens reading "windows\systems32\cmd.com" After I power off and restart, i can no longer get into my user account in normal mode. I restart in safe mode (earlier i was not able, but was successful after using the win xp disk and recovery console) and can access admin account to run malwarebytes, sdfix, smitfraud and panda. After they catch dozens of bad items (trojan.vundo-rogue.spywareguard-adware.mywebsearch and many other), I restart into normal mode and the cmd.com issues comes up again.

Would you like updated hjt logs?

thank you

P.S. i ran symatecs vundo removal tool just now and it did not find the vundo trojan.

Hello boatsandbeach,

Thank you for clarifying the issue regarding your posts. No, please do not post a HiJack This log. We do not analyze them in this forum.

Now, here is where you get a choice:

1) Keep this thread open and delete your topic in the HiJack This forum so you can receive help here

OR

2)Close this thread and wait for assistance in the HiJack This log forum. I can edit your post there to include the information you left out. Please note that that forum is VERY busy. That said, it is possible that the nature of your infection may require tools restricted to the HiJack This forum.

Please let me know your decision in a reply to this topic.

Hello boatsandbeach,

Okay, I have reopened your HiJack This topic here: http://www.bleepingcomputer.com/forums/t/191951/i-just-cant-get-rid-of-it-something-keeps-starting-a-new-windowssystem32cmdcom-virus/ and added in the summary information from your earlier post in this thread.

I shall delete the other two topics which I closed as they are pertaining to the same issue.

Because you have a log posted, 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 continue to 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.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

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

Orange Blossom :thumbsup:
