For the first time, a virus has wormed its way into Microsoft's popular MSN Messenger Service--but the slow-moving, crash-inducing pest is unlikely to cause significant damage.
Microsoft posted a warning late Friday night about the so-called W32/Hello virus on a special site and has been working with security companies to kill it. A Microsoft spokeswoman said few instant messenger users have been tricked into opening the virus, thereby slowing its potential to make other machines crash.
W32/Hello, an Internet worm that affects computers with the Windows operating system, arrives via MSN Messenger as a file called Hello.exe. If someone clicks the Visual Basic 5 application, the worm creates an unnamed shortcut in the Windows Start-up folder. It will then send a copy of itself and the message "i have a file for u. its real funny" to people on the MSN e-mail contact list of an infected IM user's machine. --Rachel Konrad, Special to ZDNet News
