Hi,

My computer became infected and I backed up my files.
I'm in the process of wiping my hard and starting over...etc


Is there a good way to scan my dvd back up files so I don't re-infect my clean system?

Also if my files have become infected ....how do you clean them or reinstall them so they don't infect the clean system ?

I was using the free AVG Ati Virus software but it didn't defend my computer against the win/32 Heur virus
and I'm afraid that my backs DVD may have this virus on them.


Thanks in advance for any help on this subject.
Basil

Check the DVD with malwarebytes and let's see if we have a problem first. Are the files copied to a DVD+-R?

The process of cleaning your computer may require temporarily disabliling 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.
alternate download link 1
alternate download link 2
  • 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

Hi rigel,

I used DVD+R for my back up files.

I haven't gotten my newly cleaned computer back up and running yet ....but I will download Malwarebytes Anti-Malware as soon as I do.
Question...Can Malwarebytes Anti-Malware scan the DVD of my back up files while it's being read from the DVD/Cd Player... before I put them on the hard drive?

It should. Use full scan mode.

Before you scan the DVD, make sure you have a secure firewall, updated antivirus, and Windows updates completely run. It will not be able to cure the files, but it will warn you before you transfer the files to a clean computer.

Hi rigel,

Good Plan. I'll check back in when I start the process.

Do you have recommendation for a Anti Virus program?

I like Comodo Internet security. It offers a firewall and antivirus that work great for me. If you only want a antivirus package, just select AV only in the setup.

rigel,


I just finished getting my cleaned notebook back up and running...I'll follow your advice and see what come ups in the Malwarebytes Anti-Malware scan before I install any back up files into my newly clean sysytem. It there any way for a virus to enter a computer by just viewing it on DVD?

Thanks

There is always a possibility.

Not what I want to here :thumbsup: ....I was going to do the whole Malwarebytes Anti-Malware scanning of the back up DVDs as you recommended but now I'm not sure yet

Hi rigel,


I'm looking into a program called Sandboxie....ever here of it.
My thought is if I can keep anything that may be on the back ups from getting to the operating system I'll at least have a change to scan the files and not install anything that is a threat.


Any thoughts on Sandboxie?

After doing some research I don't think the sandboxie program will help me to identify any virus by scanning the DVD's

Seems like a good product for browsers and trial programs ....just don't know if you can run a sandboxed version of Malwarebytes Anti-Malware and keep your dvd scanning in a sandbox. Still trying to figure this idea out though.

Hi rigel,


maybe this SandBoxie Program can do what I'm thinking.

1. What I want to do is... make anything that starts from the DVD/CD drive placed in a Sandbox.
2. I want to install Malwarebytes Ant-Malware and scan all my backup files before I would ever think of placing them on the C Drive.

All I want is a change to clean my backup files or scan the files so I know which ones not to install.



"If you have an anti-malware program running normally on your computer, outside of the sandbox, it can look inside the sandbox folders the same as it can with any other folder. Also, sandboxed programs are seen by the anti-spyware or anti-virus program, when they appear in memory.

If a program is installed inside a sandbox, then it's actions may allow you to see that it is not behaving right. Only minor changes can be made to your system by such a program, and easily reversed - perhaps change the wallpaper or the system time/date. Your Windows and Program files are safe. You can restrict any sandboxed program from accessing folders, such as My Documents, or make that access read-only.

Delete the contents of the sandbox, and a program installed in the sandbox is gone. Files/changes that were written inside the sandbox will also be gone, unless you previously gave permission to allow those items out of the sandbox. "


Any thought on this subject?
