Updated to Avast! Free 11.2.2262 today, rebooted, and immediately had problem with a payment gateway's callback java scriptlet hanging, both in IExplorer 11 and Chrome browsers, both of which are up to date. I used the payment gateway earlier today with no difficulty, and have just tried it on another PC where it also behaved normally.
Has anyone else noticed similar problems, and can anyone suggest what might be causing it?
