Is it 128 bits VPNs & Proxies, a safe mode to surf anonymous today? There are 256 bits system to do the same?
There may be some 256 bit systems out there for internet security but I am not aware of them.
I personally just use a good Router/firewall and personal firewall for internet security along with a good antivirus program and a hosts file as mentioned in your other thread. It rare for me to get any infections on my computer.
As far as trying to hide myself from others on the internet, I don't bother. If someone REALLY WANTS TO FIND YOU, they probably will regardless of your efforts. Through the legal process, all connection records can be seen by law enforcement officials allowing them to track you right back to your home, even through VPN and proxy connections.
