A customer with a laptop could not view email in Outlook or view product details when shopping online.  I checked for malware, viruses, damaged windows system files, etc.  I reset Internet Explorer.  We still couldn’t figure it out.  Then I started looking at Installed Software.  Over time, the customer had downloaded and installed all sorts of what I call “Junk Ware”.  Toolbars, Games, Coupon gadgets, you name it.  I uninstalled most of it.  Problem solved!  A lot of this “junk ware” is either buggy, a security risk, or does unexpected things to both Browsers (IE, Firefox, Chrome) and Email programs like Outlook, Thunderbird, or Windows Mail.  In general, the fewer installed programs, the better.
