Welcome to the Virus Encyclopedia of Panda Security.
It infects files with an EXE extension. It shares and grants access to all disk drives, allowing the free space on the disk drive to be used up.
Nimda is a dangerous worm, which is highly contagious and difficult to recognize. It spreads extremely quickly using its own methods, through the following means:
The danger of Nimda lies in its capacity to spread and infect, which allows it to access all local disk drives (Windows 2000 Pro and Windows NT) and all the disk drives (Windows 98 and Windows 95) shared in a computer network.
Its aim is to spread to as many computers as possible and infect all the files with an EXE extension that it finds. It activates when the user opens the programs Word and WordPad.
It is difficult to know if you have received the message carrying Nimda, regardless of the means of transmission used.
The only clear indication that Nimda has reached your computer is a file called README.EXE, which is attached to the e-mail messages that are infected with this virus.
