Computer virus in Windows Task Manager.

Thats no problem you can go ahead and select yes to end process tree of Nvctrl.exe But this should be done every time you log on your computer. A simple solution would be to get your computer with updated anti virus software.

May I know what anti virus/firewall is installed in your computer? If so check if auto-updates is enabled.

Are u sure the virus infected file is nvctrl.exe..If yes end it ...ignore the warning beacause System process if any could not be killed by task manager.

If its getting killed than ok..no system instability issues, remove it from System startup by running msconfig on run prompt..download a good antivirus like Nod32 or Kaspesky and leave on it..

Let me tell you the bad news first. You've been infected by a virus called trojan.zlob.E or a variant thereof. The good news, however, is that it's a pretty mild trojan and all it wants to do is mess with your Microsoft Internet Explorer preferences so it controls your home page, bookmarks, and so on. Annoying, but there are definitely more destructive viruses out there.

One place I turn for information on viruses, trojans, etc, like trojan.zlob.e is Symantec and its information-packed Security Response Center. It's pretty easy to use: just type in the name of the file that's mysteriously shown up or has been corrupted and it'll promptly return any and all matching viruses, trojans, spyware or similar.

What's really useful about the Symantec information pages about viruses (etc) like your nvctrl.exe trojan is that it details exactly what files are added, specifies what modifications are made to registry files, if any, and details what other changes are made to your machine.

Of course, knowing what a trojan or virus does certainly doesn't mean that you can manually reverse it or undo the damage manually.

Symantec recommends the following removal instructions for this trojan:

1. Disable System Restore (Windows Me/XP).
2. Update the virus definitions.
3. Run a full system scan and delete all the files detected.
4. Delete any values added to the registry.
5. Reset the Internet Explorer home page.
6. Reset the Internet Explorer search page.

But in fact, it's pretty darn tough to get all this right. If you're not already running some strong antivirus software (which would have caught this infection!) you really, really need to get one installed. But before you install one, you need to have a clean uninfected version of the OS. I'm afraid my recommendation to you is to do a good backup of your personal files and reinstall Windows from scratch.

Apply all the system upgrades from Microsoft, then install and update a good antivirus and antispyware application (I recommend Symantec/Norton Antivirus 2006, actually, and Webroot's Spy Sweeper antispyware application, available at lots of stores online and off).

Run the programs to ensure that everything's clean, then folder by folder restore your files and personal data.

Then never install or use any applications - or visit any Web sites - without having both these programs running and protecting you.

Good luck to you!

if you sure that was virus background you can stop it without worry, then search and destroy that virus from your computer. restart your computer and check if the nvctrl.exe still run in your background process that mean your computer is not clean yet from that virus. you should scan your computer using your best updated antivirus until that file not showing in your background.

Full scan is necessary for your machine. Nvctrl is a trojan.Zlob horse, which hijacks your internet settings and modifies your web-browser settings. It is necessary that you have to run a full scan using an effective antivirus and to contact an expert for assistance on how to remove it. I suggest that you visit www.bleepingcomputer.com There you can contact one of the HJT experts there for assistance. I am sure they will help you. You just have to register first and open this topic at the right forum category. Please follow all instructions that was given to you, step by step, for you to be able to remove the virus totally. You just have to provide a log for them to check and verify the status of your system. If you scan your computer, quarantine whatever it finds.

Good luck!

Hope this would help.
