Monitorize.exe and svchoost.exe

Hello everybody! I`m using a portable usb hard drive and yesterday i find on it this file: svchooost.exe, monitorize.exe and autorun.inf. They were hidden. When I try to use Kill process to terminate svchooost.exe ( who is locate in c:\windows\svchooost.exe) it appear for another 6 times. There is a way to get rid of that files? Thank you in advance!

Ok. My mistake. But there`s an answer for me? What should I do? Any Ideea?

Please insert your flash drive before we begin. Hold down the Shift key when inserting the drive until Windows detects it to bypass the autorun feature and keep autorun.inf from executing automatically.

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. Please do so and allow the utility to clean up those drives as well. Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
• 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 that is plugged in when you ran it. Don't delete this folder...it will help protect your drives from future infection.

Please download Malwarebytes Anti-Malware and save it to your desktop.

• 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.

Unfortunally the file from the stick are stii "alive". What next? Thank you in advance!

Now rescan again with MBAM but this time perform a Full Scan in normal mode and check all items found for removal. Don't forgot to check for updates through the program's interface (preferable way) before scanning and to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

Not even a second time MBM doesn`t do much. So, I formated that stick and the viruses are gone forever. But still i didn`t find out how to "kill" it. Thank you for you help anyway. Have a good day.

The instructions I provided were to scan your computer as well as the usb stick to make sure it was not infected as well.

From what you describe, it appears it was not. You still should download and run Flash_Disinfector.exe on the usb drive to protect it.

Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. Read USB-Based Malware Attacks and Please disable Autorun asap!.

You can hold down the Shift key when inserting the drive into your computer until Windows detects it to keep autorun.inf from executing automatically. However, I recommend disabling the Autorun feature on USB and removable drives as a method of prevention. This should keep the malicious file from automatically running upon insertion and infecting your system while allowing you to safely perform a scan.

The easiest way to disable Autorun on a specific drive is to download and use Tweak UI PowerToy.

• After installation, launch Tweak UI, double-click on My Computer in the tree menu on the left, then click on AutoPlay > Drives. This will allow you to change the system settings for AutoPlay/autorun.
• Uncheck the drives you want to disable AutoPlay on and click on Apply.
• Next, click on the Types in the left tree. This allows you to control whether Autoplay is enabled for CD and DVD drives and removable drives. You may need to restart Tweak UI if it closes after step 2.
• Uncheck the box to disable Autoplay for a particular type of drive.
• Click Apply.

If needed, see Disable Autorun/AutoPlay in XP with Tweak UI" for instructions with screenshots.

Note 1: When Autorun is disabled, double-clicking a drive which has autorun.inf in its root directory may still activate Autorun so be careful.

Note 2: Disabling autorun/autoplay does not prevent you from accessing your media sources. They are still available by opening My Computer and accessing the source drive (CD, DVD, usb/flash drive or external hard drive). Pictures on a camera can still be accessed through My Pictures and selecting "Get Pictures" from a scanner or camera. Media can also be accessed via the program you normally use it with such as music CDs accessed via Media Player, blank CDs via burning software, image handling software provided with the camera, etc. I strongly recommend you leave the autorun feature disabled and get into the habit of accessing your media devices manually.

Always scan USB Flash Drives after they have been used in other computer systems, even your own. An easy way to do this is to download "ClamWin Portable Antivirus", put it on your USB Flash Drive, update its definition files and perform a scan.
