I got that wrong.
Downloaded that tool but it says there's nothing on the system.
Also found another one at click here which also says nothing wrong.
I assumed the worst because I'm having the same problems as a friend who knows he has the virus.
I've also run regedit which shows several instances of win32/nachi or valla under hkey_current_user/software/microsoft/internet explorer
Still can't get onto the internet though and still no sound either.
Any other ideas what may be wrong please?
