I have just discovered that I now cannot access the www.encryptomatic.com/pstviewer/ website as it cannot be displayed. I ran IE9 (Google) without any add-ons with the same result. Again I noticed the Avast icon rotating and am wondering if Avast is doing something.
I can access the website as normal on my wife`s Windows 7 Home Premium/IE11/Google even though she too has the latest free Avast on her system.
