As the title says, I'm unable to properly scan my computer using Malwarebytes' Antimalware nor HijackThis.

Malwarebytes scans the registry for a few seconds, then closes. After this, it never scans ever again. If I reinstall, I can update definitions again and try to scan, but each time I scan it closes a few seconds in.

I was hoping to get some outside help for this, so I got HijackThis with the intention of posting a log here, but much to my dismay it also closes during scan.

My OS is Windows XP Home SP3.


Let me know what I can do.

let's try Fatdcuk's fix.

Please navigate to the MBAM folder located in the Program Files directory.

Locate MBAM.exe and rename it to winlogon.exe

Once renamed double click on the file to open MBAM and select Quick Scan

At the end of the scan click Remove Selected and then reboot.


Post the scan log. 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.

I scanned again after reboot, no infections found.

However, after rebooting another issue has presented itself: explorer.exe no longer runs at startup, nor does it work if I try to run it from Task Manager. It gives the following error:

Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.


Happens whether I type "explorer" or "C:\WINDOWS\explorer.exe"

Lets try to restore Windows Explorer. Could you check in C:\WINDOWS\ and see if explorer.exe is there? If it is not, then please try to obtain another copy of explorer.exe from a known clean computer and place it in the C:\WINDOWS\ folder and see if it works.

After that, please run a Full Scan with malwarebytes, post back the log, then:



Please run ATF and SAS:
Credits to Boopme

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware, Free Home Edition

Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.

Ok lets try Dr. Web.

Please download Dr. Web the free version & save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr. Web Cureit as follows:
Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
The Express scan will automatically begin.
(This is a short scan of files currently running in memory, boot sectors, and targeted folders).
If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
When complete, click Select All, then choose Cure > Move incurable.
(This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
Now put a check next to Complete scan to scan all local disks and removable media.
In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
In the top menu, click file and choose save report list.
Save the DrWeb.csv report to your desktop.
Exit Dr.Web Cureit when done.
Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

The scan from Dr. Web didn't find anything, so I could not save a report.

Edit: I managed to get explorer working again by deleting it and getting a copy from my XP install CD (as EXPLORER.EX_). However, I'm still having issues, now I can't open anything in Control Panel. I can navigate to it, but any time I double click on something I get the same error I got from Explorer earlier.

Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.

I don't think any of the malware is there anymore, just seems to be damage control at this point. Anything else I should try before reinstalling XP? I've tried doing "sfc /scannow", it runs but doesn't fix anything.

Edit2: Fixed that issue by getting rundll32.exe from my XP CD, nothing wrong now from what I can see.

If everything is fine then:

Create a new Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
Go to Start > Programs > Accessories > System Tools and click "System Restore".
Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
Then use Disk Cleanup to remove all but the most recently created Restore Point.
Go to Start > Run and type: Cleanmgr
Click "Ok"
Disk Cleanup will scan your files for several minutes, then open.
Click the "More Options" Tab.
Click the "Clean up" button under System Restore.
Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
Click Yes, then click Ok.
Click Yes again when prompted with "Are you sure you want to perform these actions?"
Disk Cleanup will remove the files and close automatically.

I'm also having this same problem with Malwarebytes. Unfortunatly when I rename the file to winlogin.exe and run the quickscan Malwarebytes still doesn't scan and just closes. I also tried running my McAfee VirusScan and it does the same thing. It tries to scan but before any files get scanned it just closes.

any suggestions? Any help would be much appreciated. =)
