How To: Remove a virus from your computer WITHOUT access to the Web. Need Help.

Hi, names Jess. I'm having issues with my home computer, as it has a trojan virus on it. I want to get onto the net to download some software to remove it, but everytime I try, my computer freezes. 1. Is this the virus preventing me from getting help? 2. If so, how can I remove it without the use of the internet? 3. If not, how can I fix this internet problem, and remove this virus.

Any help will be greatly recieved.

Thanks, Jess.


EDIT: I'm not very computer savvy, so please try to tone down the bigger words, and walk me through it with a little more detail, as you would with a younger person. I'm only 15, so please, try to keep it light =].

Welcome to BC

One way to try is to reboot your computer and just after the initial screen start tapping the F8 key
A black and white screen should come up offering several choices
Using the arrow keys maneuver to the entry that says Safe Mode w/networking and click Enter
You might be able to get online that way
OR
Are you able to burn a CD or do you have a thumb drive?
You can use either way to run what I'm going to recommend
The first one will be Mbam

The process of cleaning your computer may require you to temporarily disable some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.

• Make sure you are connected to the Internet.
• Double-click on mbam-setup.exe to install the application.
• When the installation begins, follow the prompts and do not make any changes to default settings.
• When installation has finished, make sure you leave both of these checked:
  • Update Malwarebytes' Anti-Malware
  • Launch Malwarebytes' Anti-Malware
• Then click Finish.

MBAM will automatically start and you will be asked to update the program before performing a scan.

• If an update is found, the program will automatically update itself.
• Press the OK button to close that box and continue.
• If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.

On the Scanner tab:

• Make sure the "Perform Quick Scan" option is selected.
• Then click on the Scan button.
• If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
• The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
• When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
• Click OK to close the message box and continue with the removal process.

Back at the main Scanner screen:

• Click on the Show Results button to see a list of any malware that was found.
• Make sure that everything is checked, and click Remove Selected.
• When removal is completed, a log report will open in Notepad.
• The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
• Copy and paste the contents of that report in your next reply and exit MBAM.

Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

When you cannot update

Since you cannot use the Internet, manually download the definition updates from another computer, save them to a flash (usb, pen, thumb, jump) drive or CD and transfer to the infected machine. Then just double-click on mbam-rules.exe to install the update. If you cannot transfer or install from the infected machine, try installing the file directly from the flash drive to your machine.

• alternate rules.ref download link 1
• alternate rules.ref download link 2

Mbam-rules.exe is not updated daily. Another way to get the most current database definitions is to install MBAM on a clean computer, launch the program, update through MBAM's interface, copy the definitions (rules.ref) to a USB stick or CD and transfer that file to the infected machine. Copy rules.ref to the location indicated for your operating system.

• XP: C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware
• Vista: C:\Documents and Settings\Users\All Users\Malwarebytes\Malwarebytes' Anti-Malware

If you cannot see the folder, then you may have to Reconfigure Windows to show it. Then perform a new Quick Scan in normal mode and make sure you reboot afterwards. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.
