I just use Shields Up (one of the tabs) to check common ports, it will
tell you
if they are accessible on the internet by bad guys. Nothing is installed
or changed. Your router's firewall will protect your systems from all but
a determined targeted non-random attack by experts with a lot of time and
sophistication. Any Gov. agencies after you?

Only the IRS, BATF, Dept. of Health, OSHA, FSA,MN Ag, and a few others. My
biggest scare was when a child died with e-coli and they were looking for a
cause. The child's class had just been to an apple orchard and ate my
apples.
