I have Norton 360 on my system but today got the message "Windows antivirus. Windows has detected spyware infection! etc..." and "Window's Security Alert Warning! Potential Spyware Operation! etc." on one of my systems. I also got an "Anti-virus Recovery Helper" desktop. After the computer displayed these messages, I got a "Virtual memory low" message and then an error message "VB" something that I didn't not have time to copy, and my computer restarted automatically. On reboot, it stated "error on boot" or something similar and would not boot up. I booted from Win XP disk, ran FIXBOOT from the dos promt, and rebooted in safe mode. In safe mode, I can see my desktop and my memory stick. I downloaded ComboFix (becuase it worked for me a long time ago), and tried to run it. But, it will not run when I double click it. If I try to reboot again, normally, the system will again go through all the above motions and then try to reboot, leading to another "error on boot" message. When I see the desktop before it trys to restart, I see a number of error messages like "winmdsn.exe failed to initialize and will have to close" or "g2mcomm.exe failed to initialize" or similar (too many, too fast to copy down). What can I do? Can anyone help? I've downloaded Hijack to a memory stick too, but can't run it. Many thanks!
