I suppose that code could be put into a worm via e-mail, concealed in a hidden application or such, but I totally wipe (reformat) the memory on mine at least twice a year and then rebuild the apps. I do much the same on my computers after making sure all my data is clean and saved.
Just for your info, I am cautious because I have been computer hacked before and they got my personal e-mails and bank info from my desktop. They did it on a private wireless network through a game port that had been opened to the Internet to aid the game. I have firewalls, but if a port is open, it's open.
I learned my lesson. I am locked up tight.
do you use "zone alarm?"
Re-formatting clear your firmware.
Sorry, I meant to say re-formatting won’t clear your firmware.
