Every day I bring up a newsletter which is opened by Adobe. Today, I got a Windows Installer screen instead and a screen trying to install Microsoft Windows Journal Viewer. It wanted me to put CD in. I didn't do that but instead restored computer to yesterday. Didn't solve the prolem. Also get error report to send to Microsoft. All his came out of nowhere.
