Does anyone know how to remove the Backdoor.Niovadoor virus? Norton tells me that it can not remove it.?

Norton should be able to remove it. Updated definitions for Norton have been around since February.

However, the malware may still be lurking in your system restore volumes so it would be in your best interests to disable system restore, reboot then re-enable system restore when you log back on. What this does is protects you from reloading the malware should you ever need to do a system restore.

Many anti-virus products cannot remove viruses from system restore thus the reason for clearing out possible infected points. For reference to this, see the link below:

Problems with System Restore

There are some problems associated with System Restore when it comes to viruses. When restore points are created they are stored in a directory that is accessible only to the System account and not to a user. This keeps the restore points safe from misuse and tampering. Unfortunately this also means that any virus scan software you may have installed can not scan the files located there as well. This causes a problem if a file that is infected with a virus gets backed up into a restore point because now the anti-virus software can not clean it. Now if you ever restore from a restore point, that file that is infected will be introduced back into your system.

Run another Norton scan after you purge System Restore and see if it still picks up the malware.

Answer 3

Try running Norton again in Safe Mode. Also, turn off System Restore until you've gotten rid of the beast.

To get into Safe Mode:

1.Log out and reboot your machine.
2.When the machine starts the reboot sequence, press the F8 key
3.Select Safe Mode from the resulting menu.
4.The machine will continue booting, but the Windows desktop will look different. You won't be able to see the Internet, for instance. You may have to log in as Administrator to delete the bad files.
5.When you're finished, log out and reboot back into normal mode.

Good luck.

Answer 4

go to symantec website and do a search for the virus. it will have it and will provide specific instruction on removing it. if the norton website does not have it listed, try a couple others, such as mcafee. also, try running a few different scans from other sites and seeing what they come up with.

Answer 6

most virus are spread through IE. IE is not a safe browser. you should use a more secure browser to protect your PC from virus.

i recommand you to use firefox with Google toolbar. firefox can block any any popup and disable any virus and adware, spyware on webpage, so, firefox is much safer than IE browser. as you know, most of virus spread throught internet and webpage.

besides, firefox is much smaller than IE, so it run faster than IE.

download firefox for free, Just have a try:
