If you mean how to delete a virus from whatever folder it came from, it's best to delete the entire folder. Use an Antivirus or see where the file was downloaded.
To remove this virus install escan and update virus definition. Scan full computer & USB device. I too have a problem with nhatquanglan, I was infected with this virus. Usually the target is a shared folder. From my own experience, all my shared folder and sub folder has an nhatquanglan inside. Just buy kaspersky anti virus 7.0 or try the trial version it works fine for me.
You have to look for it, any files that look like they shouldn't belong you might want to delete. It can really be hidden anywhere, but the most common places are the Temp folder, System32, and the Windows folder. Check your Temp folder (Start> Run > %temp%), sometimes a virus can be sitting there in plain sight. Try not to delete the System32 folder though ;).
i found a way to remove it using my registry systems. the virus was backdoor.trojan which is worm virus dats why it keeps on coming back even when you thought u had removed it. following symantecs removal of worm virus i was able to delete it from my restore folder.
have you tried to delete the folder? do you have the virus scanner it will help you tell if it is a Trojan virus. what does the folder have in it? did anyone download any unknown type of file to start the folder? hope i helped you! :)
go to downloads or to program files. or easily search for it (assuming you know the name of it then delete files in the folder. or if you are afraid of virus, trojans... then download or just run your virus/malware remover. good luck
a virus will move itself to any folder on you computer. the only way to find one and to be sure it's a virus, is to use anti virus software and run a full scan on your computer. If a virus is caught by a virus scanner it will be deleted or moved to the Quarantine folder.
You can remove this virus automatically or manually. For automatic removal check out http://www.spyware-review.net - a few spyware removers featured there. If you want a manual removal, it's more difficult and involves messing with your registry in the LOCAL_HKEY_USER folder and disabling programs that are associated with virus remover 2008, which is fake scamware.
If you share a folder with someone else then that means they have access to your computer. A virus will notice that and worm it's way over to both of your systems.
To enable registry after virus has disabled it , first use an antivirus to remove the virus. but antivirus cannot enable registry , so you need a small free tool called : smart virus remover this tool is not a full antivirus but it has the ability to remove virus effects ( enabling regestry , enabling folder options and show hidden files , enabling task manager ) it also has ability to remove small viruses like autorun .
Generally, folder options disappear due to virus
You shouldn't get a new folder, System32 is a virus and you should delete it instantly.
