I have a pc running windows 7 64bit. a week ago i noticed i had gotten the 2012 antivirus virus. it has messed with my firewall and network sharing capability's. Now my computer wont boot past the loading screen. Have tried safe mode as well and nothing works. system repair says it can not fix the problem as well. Any help with this issue would be great.

Hi and :welcome:

Lets give it a try. You will need a USB (Flash) pendrive.

For x32 (x86) bit systems download Farbar Recovery Scan Tool and save it to a flash drive.
For x64 bit systems download Farbar Recovery Scan Tool x64 and save it to a flash drive.

Plug the flashdrive into the infected PC.

Enter System Recovery Options.

To enter System Recovery Options from the Advanced Boot Options:
  • Restart the computer.
  • As soon as the BIOS is loaded begin tapping the F8 key until Advanced Boot Options appears.
  • Click on Repair your computer menu item.
  • Select US as the keyboard language settings, and then click Next.
  • Select the operating system you want to repair, and then click Next.
  • Select your user account and click Next.
On the System Recovery Options menu you will get the following options:

Startup Repair
System Restore
Windows Complete PC Restore
Windows Memory Diagnostic Tool
Command Prompt

  • Select Command Prompt
  • In the command window type in notepad and press Enter.
  • The notepad opens. Under File menu select Open.
  • Select "Computer" and find your flash drive letter and close the notepad.
  • In the command window type e:\frst.exe (for x64 bit version type e:\frst64) and press Enter
    Note: Replace letter e with the drive letter of your flash drive.
  • The tool will start to run.
  • When the tool opens click Yes to disclaimer.
  • Press Scan button.
  • It will make a log (FRST.txt) in the flash drive. Please copy and paste it to your reply.

Download the enclosed file.

Save it in the USB drive. Insert the USB drive in the ailing computer and run FRST once again. This time around click on the Fix button and wait.

The tool will make a log on the flashdrive (Fixlog.txt). Please post its contents in your next reply.

If successful, attempt to boot in Normal Mode. If able to do so, run Combofix as follows:

Please download ComboFix from Here or Here to your Desktop.

**Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**
  • Please, never rename Combofix unless instructed.
  • Close any open browsers.
  • Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

    -----------------------------------------------------------

    • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
    • Click on this link or this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.

      -----------------------------------------------------------

    • Close any open browsers.
    • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
    • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
    • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.

    -----------------------------------------------------------

  • Double click on combofix.exe & follow the prompts.
  • Install the Recovery Console if prompted.
  • When finished, it will produce a report for you.
  • Please post the "C:\ComboFix.txt" .
**Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

Note: ComboFix may reset a number of Internet Explorer's settings, including making it the default browser.
Note: Combofix prevents autorun of ALL CDs, floppies and USB devices to assist with malware removal & increase security.

Please do not install any new programs or update anything (always allow your antivirus/antispyware to update) unless told to do so while we are fixing your problem. If combofix alerts to a new version and offers to update, please let it. It is essential we always use the latest version.
