Two instances happened recently to prompt me to ask you to be careful with your information.
1) There are reports of over one hundred bogus health insurance web sites that have been created recently. Many like healthcare.com (as opposed to .gov) or obamacare.com are sites to get you to provide personal information. They are not part of the official www.healthcare.gov site.
2) We have gotten phone calls here at work – people saying they have determined our computer is infected with a virus and they are calling to help us get rid of the virus.
Both of these are scams.
