your statement that my pc is not protected well enough is first of all a joke. my pc is very well protected, but a good hacker does have no problem hacking into even goverments, banks and big companies.
So assuming that your safe .... think again having a good firewall and and a router does not mean your safe at all
His/Her statement is correct, your computer is not secure enough, not even mine is. However my Bitcoins are not stored on a computer, but a paper wallet.
So unless someone comes and takes it away from me physically, then it's pretty darn safe. (It's not even at my house, but a secure location).
It's also known that governments do not have the biggest protections systems, read some articles online from Whitehats, they will tell you that their computer at home is more secure.
