Last week we started looking at securing your home network. Today we will finish our walk-through. There are other settings for your router I have not mentioned but with instructions in hand you can experiment. Just be very careful and (maybe) check with a geek friend first. In review: Open your browser and go to…
If someone has access to your computer, there are many ugly things they can do. There are the obvious, like letting someone get your tax returns, i.e., your social security number, watching what you are doing, checking out your checking account, and taking personal items off of your computer.

I wrote a column last year about passwords. Gee, don’t our digital worlds revolve around them? If you work with computers on a regular basis you may have a million of them.
