I started having problems with my notebook earlier this afternoon. First, I could NOT find the usual button for internet access on the right side of the horizontal bar on my desktop. When I look for it under Networks it is labeled as unknown. Second, Microsoft Outlook stops working when I start it. I first discovered this when I rebooted under Safe Mode to find out if this corrects the problem. Third, I get a warning message to a) Turn on Windows Firewall, and b) Change Windows Update settings. Clicking on these do NOT correct the problem, ie, Windows Firewall remains off and Windows Update setting are NOT changed.
