I am the only one in my household that takes PC security seriously. Can my laptop become infected by their lousy PC's if we use the same internet?


Additionally, is using a cable to connect to internet safer than connecting wireless / wifi?

Think of it this way,

It's Flu season and you have had your recent Flu shot.  Would you rather be in a room for 8hrs with 50 people who have not had their shots or a room with 50 others who are indeed protected?

Security is often implemented at numerous and various layers: on the Perimeter, on the Gateways and Intermediate Layers as well as on the End Points.  The point being you are only secure as your weakest Link.

In short : Yes to both of your questions.


Do you have kids ? You can always install avast on their computers, tweak it to high protection levels and set it to password lock so they won't uninstall it / get around it. That'll do for 99% of malware. If your computer is acting weird then consider running malwarebytes, zemana portable and hitmanpro, also consider running adwcleaner and jrt, all of these in combination will remove almost any malware, except for some advanced rootkits. If you run all of these and your computer is still acting weird then ask malware support on this site for help or reinstall your computer and configure your firewall to public network setting.

The answer is actually, "Yes, you can, for certain kinds of infections."


That being said, if your computer has any decent realtime scanning protection for viruses and malware you are most likely going to be just fine if you follow even most of the practices in Quietman7's Best Practices for Safe Computing  (or even a good deal of them).


Most, not all, but most computer infections are not really transmitted "through the air" like real infections can be and where being in close proximity to infected others is almost certain to infect you.  They generally require direct user action of some kind to invite them in.  The one best indicator of your potential for infection is your history of infection.   None of us have been merrily strolling through cyberspace not being surrounded by potential infections for a very, very long time now.   If you're not getting them, and I don't mean getting them but your security software neutralizing them, but not getting them at all (or very, very seldom) it matters little what surrounds you if you don't directly interact with it.
