Worm.Nenebra.A is a computer worm that can eventually lead to an ultimate system crash, if you allow this malware to remain in your computer. This worm usually spreads via removable and fixed drives. If the lone Worm.Nenebra.A infection weren’t enough, it can also connect to FTP sites and download other malicious components that can surely mark the doom of your computer.

When Worm.Nenebra.A enters your system, it injects a code into the Registry that allows its components to run automatically whenever you boot your computer. For example, such process files as Ev~NeN^e.eXe, m.2FF6F.tmp.exe and TemDono FiX v1.2.exe are directly associated with the worm, and usually, when your computer is running slow or you are unable to run certain programs, you should look for suspicious processes in your Windows Task Manager, but the problem with Worm.Nenebra.A is that it blocks certain processes as taskmgr.exe (for Windows Task Manager) is one of them. Other processes that Worm.Nenebra.A is known to block are cmd.exe, msconfi.exe, regedit.exe (which means that you cannot open Registry Editor to remove the worm manually) and taskkill.exe.

Also, when it is installed, Worm.Nenebra.A copies itself to a particular desktop folder, so if you have an unfamiliar folder on your desktop, and you can no idea where it came from, time to check for some malware. Since Worm.Nenebra.A spreads through removable drives, you should disable the Autorun, because the copy of the worm is dropped automatically, whenever the new drive is accessed. Also, you should check any removable drive for viruses before opening it.

Once Worm.Nenebra.A is fully installed, it can easily bypass your firewall and connect to remote servers, downloading even more malware. As a result, the worm does not allow the user to check hidden system files and folders, thus prolonging its stay in your computer. The tricky thing about this worm, is that it might take you some time before you notice that something is wrong with your system, and when you do, the worm might have already be spread too wide to do something about it. Therefore, you have to perform regular security checks, and system scan to avoid this computer threat. Invest in a reliable security tool that will remove Worm.Nenebra.A automatically for you, and you will not have to worry about your system’s security anymore.
