Hello everyone. This is my first post, but iv been looking at these forums for awhile already. My problem is this.

I have an external hard drive which serves as my back up memory for all my files, be it anime, videos, academics, papers etc.... The problem started when i plugged it into a friends computer. Suddenly, the filenames of the folders had a '.exe' added to their names, but they were still folders. add to that is some of these wont open.

When i ran it in my friend's norton internet protection antivirus and the trendmicro antivirus, none was detected. So i assumed that the virus didnt latch on to my hd, and that it remained in the computer. But, when i plugged it back to my desktop, my nod detected numerous viruses. After cleaning them, a few viruses would be removed (theres always a conficker worm warning that keeps on popping up, telling me to reboot but it doesnt get cleaned after rebooting) i couldnt find some folders which were hidden, and some which werent.

At first i panicked because i thought that these were deleted, but upon running my antivirus to scan the hd, it scanned the different folders which led me to think that 1. they were still there and 2. i am dealing with a virus. I tried to edit the registry by changing the value from 0 to 1 but it didnt work. Setting the view hidden files under the tool command also didnt work.

Thus, i do not know what to do now. any suggestions would be appreciated....

Wait for a Advisor to assist you
If you have MBAM, Update and Run it

If it doesnt open, rename it or change the extension

hello let's try scanning all drives with...
Show hidden files and then update and scan with MBAM.

Close all programs so that you are at your desktop.
Double-click on the My Computer icon.
Select the Tools menu and click Folder Options.
After the new window appears select the View tab.
Put a checkmark in the checkbox labeled Display the contents of system folders.
Under the Hidden files and folders section select the radio button labeled Show hidden files and folders.
Remove the checkmark from the checkbox labeled Hide file extensions for known file types.
Remove the checkmark from the checkbox labeled Hide protected operating system files.
Press the Apply button and then the OK button and shutdown My Computer.
Now your computer is configured to show all hidden files.


MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

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. Temporarily disable such programs or permit them to allow the changes.
  • 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 definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Ive tried downloading the software, the first two sites wont load. The third link works but the downloads dont. Instead, a 'server not found' is displayed...

I searched out a torrent file instead and downloaded version 1.35

After performing the scan, I wasnt able to reboot normally. I ended up rebooting with the last known settings, and unplugging the external HD. I wasnt also able to update successfully, the manual update link doesnt work for me... Here's the log:

Hello,some not so great news here. One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.

Ah... I expected as much. Good thing I only use this computer for games and watching vids. I was wondering...

Its possible that trendmicro and norton didnt detect the virus in the external HD? or was the virus already inside the computer in the first place?

I've heard that viruses only travel with .exe files... is it true? meaning if a usb containing only .avi, .doc or .jpg files, there is a significantly lesser chance of a virus getting inside it?

Is it possible for a virus to allow only selective browsing on the internet? Meaning when I browse select sites like eset or symantec, the connection times out and I cant access it, but I can browse others?

Do you think we can successfully remove the virus? I've been trying to remove it for a very long while, but I've noticed that when I thought it was all clean, it comes back..

I wanted to reformat my computer for a very long time already, but can I do it without a windows cd? When I bought my computer, it came with windows installed already...

Hello, that is hard to say for certain. I 'd suspect as on was attached in system drivers that it was in the main system.
Are you running to active AV's ?? TM and Norton?


The .exe thing is true see my Reformatting notes below.
If you uses a USB /flash drive device it needs to be cleaned as it will spread the infection. Run the Flash Disinfect or tool below from this machine if possible. Run it on the flash drive and this and any other PC that drive contacted.

We can get it off but i remind you //Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. //

Did you get a repair or restore disk?
********************
Download and Run FlashDisinfector

You have a flash drive infection. These worms travel through your portable drives. If they have been connected to other machines, they may now be infected.
Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
The utility may ask you to insert your flash drive and/or other removable drives including your mobile phone. Please do so and allow the utility to clean up those drives as well.
Wait until it has finished scanning and then exit the program.
Reboot your computer when done.

Note: Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive plugged in when you ran it. Don't delete this folder. It will help protect your drives from future infection.

**********************
ot an unwise decision to make. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore removes everything and is the safest action but I cannot make that decision for you.

Reformatting a hard disk deletes all data. If you decide to reformat, you can back up all your important documents, data files and photos. The safest practice is not to backup any autorun.ini or .exe files because they may be infected. Some types of malware may disguise itself by adding and hiding its extension to the existing extension of files so be sure you take a close look at the full name. After reformatting, as a precaution, make sure you scan these files with your anti-virus prior to copying them back to your hard drive.

The best proceedure is a low level format. This completely wipes the drive. Then reinstall the OS.
Use the free version of Active@ KillDisk.
Or Darik's Boot And Nuke

The best sources of Information on this are
Reformatting Windows XP
Michael Stevens Tech

Of course also feel free to ask anything on this in the XP forum. They'd be glad to help.
==============================
2 guidelines/rules when backing up

1) Backup all your important data files, pictures, music, work etc... and save it onto an external hard-drive. These files usually include .doc, .txt, .mp3, .jpg etc...
2) Do not backup any executables files or any window files. These include .exe's, .scr, .com, .pif etc... as they may contain traces of malware. Also, .html or .htm files that are webpages should also be avoided.

Strangely enough, when I tried the system restore function built in to the computer, I was already able to view the files. The combination of the removal of the malwares / viruses plus the restoration of the original settings must have led to this! I was wondering, ever since that time, I've noticed that the speed of my internet connection, or rather the speed the internet browsers load the sites have noticeably slowed down. Now, after a limited amount of time, i lose the connection to the net! This only applies to my browsers though (mozilla and IE) since my other softwares (utorrent and YM) are still connected... Once again, I don't know how to solve this...
