In the form of a router.
Most if not all of them have firewall capability and you can encrypt them with your own 64 or 128 bit encryption, in addition to yur financial institution encryption.
This will protecty you against inbound attack, but you should know that when you open a website in your browser, you are in fact opening a port to your PC, so be careful where you go.
McAffee has a 'site advisor' that is at least IE 6.0 compatible. It will warn you of sites that it is aware of that are potential problems.
This is my problem:
For the past three months, my on-line banking transactions have been infiltrated and thousands of dollars have been charged to my account from a variety of sources, commercial businesses and other places(none of which I authorized, let alone heard of). I contacted my bank, which recredited my account and cancelled my debit card, more recently for the third time. I have been advised that I needed to download a firewall program(other than Windows Firewall). I did, but some of those programs were more trouble than they were worth, stopping to get my approval for almost everything that I had in my system as well as incoming stuff. I now have Lavasoft Firewall and it has intercepted and blocked a number of Ethernet Attacks.
When I receive my next debit card, will Lavasoft protect future unauthorized debits? Will I have to do more re security? Is there ANYTHING I can do to stop this nightmare?
