Re: Laptop virus Free?

Hi,

Please do the following:
  • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before following the steps below.
  • They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
Copy/paste the text inside the Codebox below into notepad:

Here's how to do that:
Click Start > Run type Notepad click OK.
This will open an empty notepad file:

Copy all the text inside of the code box - Press Ctrl+C (or right click on the highlighted section and choose 'copy')

Code:
DelDomains::

FCopy::
C:\WINDOWS\SoftwareDistribution\Download\cf8ec753e88561d2ddb53e183dc05c3e\proquota.exe | c:\windows\system32\proquota.exe

Folder::
c:\documents and settings\All Users\Application Data\97373586
c:\documents and settings\All Users\Application Data\17363594
Now paste the copied text into the open notepad - press CTRL+V (or right click and choose 'paste')

Save this file to your desktop, Save this as "CFScript"


Here's how to do that:

1.Click File;
2.Click Save As... Change the directory to your desktop;
3.Change the Save as type to "All Files";
4.Type in the file name: CFScript
5.Click Save ...

  • Referring to the screenshot above, drag CFScript.txt into ComboFix.exe.
  • ComboFix will now run a scan on your system. It may reboot your system when it finishes. This is normal.
  • When finished, it shall produce a log for you.
  • Copy and paste the contents of the log in your next reply.

CAUTION: Do not mouse-click ComboFix's window while it is running. That may cause it to stall.


NEXT


Please navigate through windows explorer (windows key + E) to the following directory:

c:\windows\System Volume Information

(this is not the normal location for system volume information)

Take a look inside and tell me if it contains any data.

If the folder is empty - please delete it (right click > delete)

If it contains data please give me a brief sample of some of the files (anything .exe or .sys or .dll)

Note: this may be a hidden folder, so you will need to show hidden files and folders if you cannot locate that folder initially:

to show hidden files and folders:
  • Double-click My Computer.
  • Click the Tools menu, and then click Folder Options.
  • Click the View tab.
  • Clear "Hide file extensions for known file types."
  • Under the "Hidden files" folder, select "Show hidden files and folders."
  • Clear "Hide protected operating system files."
  • Click Apply, and then click OK.
