I got a message from my McAfee antivirus that vundo and vundo.dll had been detected on my system. It could not clean or delete the files. My system became very slow and i kept getting the pop-up from the anti-virus about vundo and vundo.dll, so i tried restarting my computer. while shutting down it gave a blue screen saying some fatal error in logon ..and when the machine restarted it gave a winlogon error message. But now the vundo messages are not comming up. I am not sure if my system is infected. Any help will be much appreciated. Thanks, Vikas
