amazonaws

I use Reckon Accounts for Home and business to manage my finances, even though I closed the business some time ago. For the last two weeks, when I click on the update button for share price updates, Reckon gets the share price updates without problems. BUT my Malawarebytes program warns me it has blocked an outgoing connection to:
s3-ap-northeast-1.amazonaws.com generated by qw.exe.
I am not game to exclude this from warning as I read that the legitimate amazonaws site is being used to spread criminal programs. Please advise.
