Maybe, thats a huge file for a virus or trojan.

Or it brings just garbage, like some Windows 95 virus which just filled your harddrive up with text files until the last kilobyte.

And you needed to find the original one to stop it :)

Lol, he isn't a test subject.

Also, MBAM still won't work. Fresh copies will not install either. Skype will not load aswell, he's using an iPod right now

OK methinks it may be additional stuff

Download and Install Combofix
 
Download ComboFix from one of the following locations:
Link 1
Link 2
 
VERY IMPORTANT !!! Save ComboFix.exe to your Desktop and rename to Gotcha
 
* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here
  • Double click on ComboFix.exe & follow the prompts.
  • Accept the disclaimer and allow to update if it asks




  • When finished, it shall produce a log for you.
  • Please include the C:\ComboFix.txt in your next reply.[/b]
Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.

3.  If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.


Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

THEN

Download aswMBR.exe ( 4.5mb ) to your desktop.
 Double click the aswMBR.exe to run it  Click the "Scan" button to start scan 




On completion of the scan click save log, save it to your desktop and post in your next reply

Essex, he's using Windws 8, not 7.

OTL just sent some Thumbs.db file to the desktop as unhidden, YOu're right. This might be a pain and extensive cleaning process.

More issues: No Internet.

The screenshots just show the installation files running around, after the restart nothing is showing up like malware.

Essex, I've given this link to Mach to see if he can learn anything. if he has any advice or anything, fire away once (If he still has to confirm) he's confirmed a idea.

Uhhh. Thta's not good. I flagged the YT video. I'll check to see if it's down.

YT video confirmed removed. Any word on the CF Log Essex? There is more active malware, that for sure

OK there is no further apparent malware however, I would like to now check out the MBR

Download the latest version of TDSSKiller from here and save it to your Desktop.
 
 
  • Doubleclick on TDSSKiller.exe to run the application


  • Then click on Change parameters.
     

     
  • Check the boxes beside Verify Driver Digital Signature, Detect TDLFS file system  and Use KSN to scan objects , then click OK.
     
  • Click the Start Scan button.
     
     
  • If a suspicious object is detected, the default action will be Skip, click on Continue.
     

     
  • If malicious objects are found, they will show in the Scan results and offer three (3) options.
  • Ensure Cure is selected, then click Continue => Reboot now to finish the cleaning process.

  • Get the report by selecting Reports

 
  • Note: If Cure is not available, please choose Skip instead, do not choose Delete unless instructed.
