Adding usb stick gives me an avast service error

[Lisandro]

When I insert an usb drive (that could be read in other computers and is clean), avast service gives me an error on the Windows Events.

Code: [Select]

Tempo limite esgotado (30000 milissegundos) ao aguardar a resposta de uma transação do serviço avast! Antivirus.Translation: Time limit finished (30000 milliseconds) while waiting for an answer to an avast antivirus service transaction.

Some seconds later, the same error for the avast Web Scanner service and the avast Mail Scanner.
If I boot or do not use the computer, the error does not appear.

What is that?

I can "uninstall" the usb stick (with usbdeview) and load it again.
Windows installs the new device.
Same error.

Seems a CTM 175 beta issue (already acknowledged)
