Hello. The subject line says it all. Every so often the virus checker will pop up and when it does I am unable to speak to anyone on the phone, although I can hear them they are unable to hear me. This happens whether the call is in coming or outgoing. I then receive a text message from "n" with no message in the body of the message. I have obviously done something which I shouldn't have, but what? This problem does not happen all of the time thankfully but is frustrating when it does. Can anyone throw any light on this and how I can sort the problem out? Many thanks. Matty.
