Question : antivir Solution Pro

there is a possible virus infection, even though avast was running.

The error message from the spurious software is:
"Windows Security Alert: App cannot be executed. The file ytbb.ee (another time wuauclt.exe) is infected. Do you want to activate your Anti virus Software?

Win32/Nugel.t infection from 224.183.83.47 port 15741, attacked your port  62721. Your computer is being attacked by an internet virus. It could be password stealing attack.
------------------
i ran Malwarebytes and Avast in safe mode, but did not catch anything.

how would you proceed on that?

thanks
