Hi. I'm not sure if this is a bug in windows or something really bad (as i suspect).
For the 2nd time in the past week, several things on my computer are temporarily disabled.
These include right click menus, task manager (from pressing ctrl+alt+del), and starting new programs.
Also, no error messages appear when I try running task manager, only an error sound is played.
Both times I was connected on the internet doing normal tasks (ie word processing, msn, email, etc.)
I suspected that someone was trying to access my computer so I disconnect my wireless connection and
soon, the problem goes away.

I've run Ad-Aware, and it claims to have removed a 'Win32.Backdoor.Hupigon.' But that was
a few days ago, before the second occurrence. I've also run SpyBot SD (after updates of course) and it
only found a few cookies. Aside from using Ad-Aware and Spybot, I have Avast (home ed) running with
all services on the 'high' setting. I am also using the Windows Firewall.

I'd also like to mention one last thing, because I believe it must somehow be related or connected to my
current problem. Before the first occurrence of this problem, several of the common Windows programs
disappeared from my system. These include: MSPaint, Volume Control, Sound Recorder, Minesweeper and
the other games, calculator, character map and wordpad, along with the associated help files. I searched for
them and found them in the C:\Windows\LastGood. I noticed that all the files that were missing had the same
time stamp. Checked it a minute later and their time stamps were reset to Aug 2001. I looked for the folder today
and I can't find it anymore. In any case, this isn't really the main problem I'd like to address in this topic.

If anyone can help me figure out why my right click menus, task manager, etc get temporarily disabled,
it would be a great help. Thanks.

System: Microsoft Windows XP Professional Version 2002 SP 2

Let's try another malware scanner

Please download Malwarebytes Anti-Malware (v1.34) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

I suspect this infection was mishandled by adaware?

Just use the following to verify if teatimer has been running resident

We need to disable Spybot S&D's "TeaTimer"
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

what other security programs did you have installed besides avast?

I've shut off Spybot's Teatimer and ran the malwarebytes scan again.
Also, Ad-Aware was turned off for the scan. The only anti-virus program running was Avast.
Aside from those programs, I have Windows Firewall running.
I have HijackThis installed, and I could post a log if you want, (but I've read it and I don't see anything unusual).
I also have Process Explorer and Registrar Registry Manager installed.
Those are the only programs I have installed to search for malware.

Unfortunately I need to go to bed, and so my next reply will be in about 7-8 hours.
I'll disconnect my internet just to be sure. Thanks for your help.

The problem sounds pretty serious. In the meantime, I'll just make sure to disconnect my internet when I'm not using it.

I may be wrong, it won't be the first time

:thumbsup:

You may have denied changes with teatimer that would have repaired damage from that trojan

From what you describe, your sysmptoms appear to be the affects of infection which may or may not still be present on your system. MBAM is among the best programs to use but like any security tool, it does not find every malicious file. I don't trust Ad-aware anymore.

If you had Backdoor.Hupigon, please know that this is a nasty infection. Backdoor Trojans, IRCBots and Infostealers are very dangerous because they provide a means of accessing a computer system that bypasses security mechanisms and steal sensitive information like passwords, personal and financial data which they send back to the hacker. Remote attackers use backdoor Trojans as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge. Read Danger: Remote Access Trojans.

You may or may not still be infected. We could fix your policy restrictions but if all the malware has not been detected/removed, those issues would return and we would only be wasting our time. I suggest further investigation. Before that can be done you will need you to create and post a DDS/HijackThis log for further investigation.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT Team members are very 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 "bump" your post or 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 log in the thread titled "Post in this thread when you haven't received an answer in five days.".
