I have three files that my virus scanner found, but it cannot remove them because it is saying they are inaccessable. I have AVG right now. And I am not sure how to locate the files. I am using Windows 7.

DO NOT use any TOOLS such as Combofix or HijackThis fixes without supervision.

Doing so could make your pc inoperatible and could require a full reinstall of your OS, losing all your programs and data.


Vista and Windows 7 users:
1. These tools MUST be run from the executable. (.exe) every time you run them
2. With Admin Rights (Right click, choose "Run as Administrator")


Stay with this topic until I give you the all clean post.

You might want to print these instructions out.

I suggest you do this:

XP Users

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

Click on the Start button. This is the small round button with the Windows flag in the lower left corner.

Click on the Control Panel menu option.
When the control panel opens you can either be in Classic View or Control Panel Home view:

If you are in the Classic View do the following:
Double-click on the Folder Options icon.

You might want to print these instructions out.

Download ComboFix from one of these locations:

Link 1
Link 2 If using this link, Right Click and select Save As.


* IMPORTANT !!! Save ComboFix.exe to your Desktop


  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools.

  • Double click on ComboFix.exe & follow the prompts.

    Notes: Combofix will run without the Recovery Console installed. Skip the Recovery Console part if you're running Vista or Windows 7.

    Note: If you have SP3, use the SP2 package.If Vista or Windows 7, skip the Recovery Console part
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt using Copy / Paste in your next reply.


Notes:

1.Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. ComboFix may reset a number of Internet Explorer's settings, including making I-E the default browser.
3. Combofix prevents autorun of ALL CD, floppy and USB devices to assist with malware removal & increase security. If this is an issue or makes it difficult for you – please tell your helper.
4. CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.

Give it atleast 20-30 minutes to finish if needed.

Please do not attach the scan results from Combofx. Use copy/paste.

Also please describe how your computer behaves at the moment.
Hi,y es I already had changed my password, and since then there have not been any links sent. There are sometimes pop up thats get blocked by my AVG antivirus. I downloaded combofix from Link1 and installed it. When I click on the program to run it, it says it is not compatible with my OS. I have Windows 7.
I take it you're running 64bit then. CF doesn't work with 64bit OS.

You can give this a run and see if anything is found.
