Unlike other viruses Nimda appears to be a carrier of infection, it does not appear to cause direct file damage but is responsible for loss of traffic known as denial-of-service. So, it is advisable to opt for online tech support or computer support. Nimda became the most widespread virus in the world a mere 22 minutes after it was released. It is due to its multi-pronged attack it appears to be the most troublesome virus of all times. In fact if one takes a closer look at its name it would be easy to understand why is it so destructive. Its name when spelled backwards is admin which refers to an admin.dll file that, when run, continues to propagate the virus. How it propagates? The web Shared folders Microsoft IIS security holes File transfer In particular the users of Microsoft Outlook in Windows , Millenium, NT4, and 2000 are at risk. Also any user who is connected to the network is vulnerable to this threat, this is why online tech support is essential to avoid and/ or counter this risk. What the virus does? As soon as the system is infected by Nimda worm, it immediately starts retrieving the list of addresses in the address book of Ms Outlook and Eudora,even the addresses in HTML files. Next, the Nimda virus sends out e-mails to all the recipients with an empty body and a subject chosen at random (the subject line might be long). The actual virus is contained within an attachment named Readme.exe or Readme.eml (an executable file). The Microsoft Windows are the most vulnerable as the Nimda virus can spread over shared network folders, infecting executable files found there. Another imminent threat might come across while viewing web pages on servers infected by the Nimda virus. This may lead to infection when a user views pages with the vulnerable Microsoft Internet Explorer 5 browser. The Nimda virus is also capable of taking control of a Microsoft IIS (Internet Information Server) Web server. The virus can also spread by file transfers, as it infects executable files found on the infected machine. Nimda infection Systems infected by the worm will have the following files on their hard drive: README.EXE README.EML Files with the extension .NWS Files with a name like mep*.tmp, mep*.tmp.exe (for example mepE002.tmp.exe) Nimda has in fact set records for different ways of spreading virus, one of them is sending e-mails that infected the users system on viewing. The other trick ncludes putting copies of those e-mails on network drives where other users can find them, this would then infect other systems as well. It poses a potential threat to the system and servers and so seeking computer support is essential to deal with this virus.
