amyers

For some very odd reason, after coming back home from traveling for a week, I plug my computer back in and all of a sudden I am getting message after message of "address has been blocked" The address is usually "hxxp://api.reasonsecurity.com/..." and then random letters and numbers at the end where I have the ellipses (three dots). Why am I getting this and what do I need to do? Is there something I need to reset or is a scan in order?
