Hi All,

There is a respawning process called SCtri.exe that has got hold of the PC.
Firewall access has been barred by "group policy"

My startuplist log is below. Grateful for any assistance.

Hi mcgarnacle, welcome to the forum.

Please be advised, as I'm still in training, all my replies will have to be approved by a teacher or expert before I can post them. This may cause some delays, but I will do my best to keep them as short as possible.

To make cleaning this machine easier
  • Please do not uninstall/install any programs unless asked to
    It is more difficult when files/programs are appearing in/disappearing from the logs.
  • Please do not run any scans other than those requested
  • Please follow all instructions in the order posted
  • All logs/reports, etc.. must be posted in Notepad. Please ensure that word wrap is unchecked. In notepad click format, uncheck word wrap if it is checked.
  • Do not attach any logs/reports, etc.. unless specifically requested to do so.
  • If you have problems with or do not understand the instructions, Please ask before continuing.
I will post back soon with additional instructions.


Thanks

Hi mcgarnacle,

As a Vista user you will need to right click and click Run as Adminstrator in order to run the tools we will use.

Download OTViewIt to your desktop.
  • Close all windows and right click OTViewIt and select Run as Adminstrator
  • Place a tick in the Scan all Users box
  • Click Run Scan and let the program run uninterrupted
  • On completion it will produce two logs on the Desktop, atttach the OTViewIt.txt and Extras.txt logs in your next post.

To attach a file, do the following:
  • Click Add Reply
  • Under the reply panel is the Attachments Panel
  • Browse for the attachment file you want to upload, then click the green Upload button
  • Once it has uploaded, click the Manage Current Attachments drop down box
  • Click on [external image: Posted Image] to insert the attachment into your post

Thanks

Hi mcgarnacle,

Thanks for letting me know. It will take a bit to go through these logs.

Please do not do any more scans. The logs will not reflect the true condition of your computer. Finish the one you are doing and when it's done obtain a new HJT (hijackthis) log.

Do this by
  • Opening HJT
  • click Do a system scan and save a logfile
  • a notepad will open, please copy and paste it's conrents into your next reply.
Make sure wordwrap is unchecked in the notepad. To check, at the top of notepad, click format and make sure there isn't a checkmark beside wordwrap.

Thanks

Hi

You've been infected with an autorun virus that is spread via USB devices. This infection can have backdoor capabilities I strongly suggest you change your passwords to any forum, websites, and sites you do financial transaction online with. Use a known clean computer to do this.

We'll fix taskmanger and registry tools first.

Right click the attached file 📎user.zip and click "Save target as"
  • Set the Save in box to desktop
  • click save
Locate the file you downloaded and right click it, click extract here You will now have a file on your desktop named fixit.vbs Please right click the file and click Run as Adminstator.

Please note to run these tools you will need to right click and Run as Adminstrator

Next, Download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • right click on Flash_Disinfector.exe and click Run as Adminstrator 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.

Please do the above steps for any usb devices you have until all have been done. Hook up as many as you can at a time. This includes phones, ipods, thumb drives, cameras, any usb storage device.

Next, we'll look for a file. Have your usb device(s) attached before runing this next tool. Run the fix as many times as needed to do all of your devices.

Please download OTMoveIt3 by OldTimer.
  • Save it to your desktop.
  • Please double-click OTMoveIt3.exe to run it. (Note: If you are running on Vista, right-click on the file and choose Run As Administrator).
  • Copy the lines in the codebox below to the clipboard by highlighting ALL of them and pressing CTRL + C (or, after highlighting, right-click and choose Copy):

    Do not copy the word CODE

  • Return to OTMoveIt3, right click in the "Paste Instructions for Items to be Moved" window (under the yellow bar) and choose Paste.
  • Click the red Moveit! button.
  • Copy everything in the Results window (under the green bar) to the clipboard by highlighting ALL of them and pressing CTRL + C (or, after highlighting, right-click and choose copy), and paste it in your next reply.
  • Close OTMoveIt3
Note: If a file or folder cannot be moved immediately you may be asked to reboot the machine to finish the move process. If you are asked to reboot the machine choose Yes. After the reboot, OTMoveIt3 will start automatically to finish the move process. Highlight everything in the Results pane (underneath the green bar) by right-clicking in it and choosing Select All and then right-clicking again and choosing Copy. Return to this topic and click the Reply button, right-click in the Reply window and choose paste to copy all of the results back here.

If you need to run the OTMOVEIT3 fix more than once, please
  • save the log from each run
  • post all the logs along with a new HJT log
Thanks
