8v8.biz http://www.google.com.au/search?q=8... http://au.answers.yahoo.com/questio... It's an exploit virus ,some av progs can see it . But is not a solution yet... Try to add this on restricted sites on IE like this: http://8v8.biz http://9gg.biz the last one is the same exploit address. the virus is powerful and make serious damages on the LAN ,if you have the gateway address ,can check this on cmd.exe ping "yourgatewayaddresshere" -t ,and see the reply time from your server ...must be <1ms ,if your result will be bigger about 1ms the virus is present on much more machines on your LAN.Speed connection is also afected and increase amonut of memory used by IE.On task manager you can see that .

mr johnw i have already seen this article but i want a solution

Sorry marc_gujral, when you google, you get the world & as stated, no solution is yet available. "It's an exploit virus, some av progs can see it. But is not a solution yet..."

thanks johnw for taking out ur time for me

You can make a simple change to your HOSTS file to prevent uninfected machines becoming infected. For instructions, see http://www.castlecops.com/t212462-B... However, this solution won't cure an infected machine. But if applied to all machines on the LAN, it'll mean the clean machines operate pretty normally. RFC
