I have google it but most of the pages that came up were 2-4 years old.
A port scan just checks what ports on your external ip address/domain name reply back. You can't stop them, but I'm not sure if were on the same page. Just get a NAT, and make sure it has logging.

Just turn off notification of it. You don't need to see nor worry about it.

In the case of your old computer it was likely either not secure (no firewall or lack of updated Windows) or you ran/installed the viruses thinking they were something else.

But I guess a simpel router will do... has some security, and will also NAT your IP...That's all folks.
