Norton Power Eraser Beta

The Norton team has just released the new Norton Power Eraser beta,  NPE 2.5.0.26

I hope many of you have a chance to try it and let us know what you think..
 
We look forward to reading your feedback and great ideas.
 
Key changes in this release:


•    Improved Network Resiliency
We have added additional logic to resolve network problems that prevent NPE from running
 
•    Undo to a separate partition
If you remove a file that makes the system unbootable, (certain rootkits that hook the OS for example) you can boot from NBRT or another Windows partition and undo the changes to the other OS
Note: Current NBRT does not use NPE 2.5 beta.

•    Main UI and setting layout changes
Main UI layout  has been updated with the three principal actions available as clickable button (Scan, History, Settings)
Similarly, the settings page layout has been refreshed and updated.
 
•    Setting option to only show bad files
Suspicious files that would normally be shown in the scan results can be suppressed. Users that have a high number of suspicious files that are safe may wish to enable this setting.

You can download the Norton Power Eraser Beta here:

Re: Norton Power Eraser Beta

It's always good to see that this project is not abandoned by Symantec and it's updating frequently when the threat landscape is going to change.
Whether you have included advanced rootkit detection techniques(especially against Backdoor.Tidserv.M and Trojan.Zeroaccess)into the last beta build, or the only way to detect and / or clean these rootkits is the NPE scan on NBRT environment?

That is what I did before. I followed the directions. When I tried to run it, I got the error message that it was not a valid win32 application.

Re: Norton Power Eraser Beta

OK.  Then I am out of suggestions.    Hang on until someone here can provide the information you require.

Thanks,  Dave.

Re: Norton Power Eraser Beta

Hi rcsptdisi,

Can you please check if the NPE-Beta.exe is not corrupted? There should be Symantec signature in the Digital Signature tab of Properties window. The size of the file is 2.64 MB (2,775,112 bytes) [The size on the disk may vary] Please check what the size is on your end.

Can you please let us know what OS you are running?

A common reason for the error which you are facing is that either the file is corrupted/missing or virus/malware exists on the machine.


Also, please try downloading NPE on a clean machine and then using it in the infected machine.

Let us know what happens

Thanks!

Re: Norton Power Eraser Beta

There is no Digital signature

The file is 2.41 MB   2,530,792 bytes

I don't have another machine here that I can download to.

I do hav a viruson this machine. That's why I downloaded Power Eraser

The Norton scan says  I have Trojan.Zefarch on this machine

Re: Norton Power Eraser Beta

If you are using IE, could you try downloading with another browser to see if the full file comes down?

Re: Norton Power Eraser Beta

Today I've noticed that NPE-beta got updated to 2.5.36(26 was previous build). 

There are any changes in this beta build?

Re: Norton Power Eraser Beta

These are the changes in the new build. I will be announcing these changes on the forum as well.

Key changes in this release

  • Norton Live Banner

At the bottom of the Main UI  there is a banner with a link to a Norton Live page that reads-

“Need help with a virus or spyware? A live expert can remotely remove it for you. Learn more about this paid service”

  • Rootkit Scan enabled by default

The Rootkit scan will run by default. There is an option in settings to disable this.

  • Improved usability scan results screen

‘Unknown’ files now have an info dialog pop-up to provide more information about the detection.

In order to remove an ‘Unknown’ file users will first need to click the ‘enable action on the file’ button found on the info pop-up dialog .

The Cloud Scan flow has been changed to a cloud shaped button.

Re: Norton Power Eraser Beta

Thanks rcsptdisi,

The error was due to the corrupted NPE.exe;

As Nate has suggested, Can you please try downloading on a different browser?

If it fails, can you please use the Norton Bootable Recovery Tool by visiting the following page http://security.symantec.com/nbrt/nbrt.aspx?

Regards!

Re: Norton Power Eraser Beta

I just recently used power eraser and it came up with physicaldrive0. So I continued to fix and now I cannot boot. I've tried several times to recover from multiple different recovery points to no success. There is NOTHING in support about power eraser and I've found nothing else anywhere

Re: Norton Power Eraser Beta

Sounds like Norton Power Eraser (NPE) has detected the Boot Record (MBR) and has either deleted it or incorrectly disinfected the MBR, when this happens you on booting the PC will usually get a black screen with a white flashing underscore.

Depending on the Windows you have of course for which command to use, but use the recovery disc or installation disc etc, then use the command prompt to fix the MBR

Re: Norton Power Eraser Beta

It gets to the loading screen then takes me to startup repair. I'm running windows 7 and tried restoring to the point set by norton just before I tried to fix it and even earlier ones but no luck.

Re: Norton Power Eraser Beta

Your Startup Repair is kicking in first,

For Vista / Windows 7 you have to use the bootrec tool in command prompt to fix the MBR

bootrec /[command]

examples,  

bootrec /RebuildBcd

bootrec /Fixmbr

bootrec /Fixboot

bootrec /ScanOs

Re: Norton Power Eraser Beta

Hi,

I'm getting contradictory results from different aspects of NPE Beta.

When I run a scan, two "bad" results come back, as in the screenshot below:

When I click on the cloud scan, both of them still come back as "bad." Clicking on the info button, I get something like this:

However, if I click on the individual files on the left, I get the following screens, in which the files are considered "favorable" despite the "bad" rating they just received:

Obviously both of these ratings can't be correct -- a file can't be both "bad' and "favorable." Which assessment should I trust?

More generally, this kind of discrepancy is perhaps an area where NPE can be improved while still in beta.

Also, an inline explanation of the reason why the file in question is considered unsafe, would be welcome.

Re: Norton Power Eraser Beta

Jorge,

 

Thank you for the valuable feedback.

 

While the reputation of the file is one factor used in determining if the file is a threat , Norton Power Eraser uses a combination of heuristic techniques to identify potential threats.

 

To combat new and evolving threats, Norton Power Eraser is specifically engineered to be more aggressive when detecting threats. The threshold for which a file is considered 'Favorable' , does not provide enough certainty for NPE to consider the file safe.

 

We present the individual file reputation data so that users can review this when deciding how to address the file.

We recognize that for ‘Favorable’ files this is confusing and are looking at ways we can refine the flow in an update.

Re: Norton Power Eraser Beta

Nate,

Thanks very much for the explanation.

One way to help users when faced with these kinds of "on the one hand, but on the other hand" results, would be to provide additional details on what the nature of the possible threat is (that is, why NPE thinks it's bad; or maybe a description of what it thinks the bad file does). To minimize the size of the NPE program, this information could be made available online via a link right on the program screen ("Click here for more information about this threat").

Hope this helps.
