I'm assuming most don't have a clue what your talking about. You simply can't 'anonymise' your IP address - it's an address so anything on the other end NEEDS to know it in order to send traffic to it. Your ISP assigns you an IP address, you can't chop bits off of modify it. The only way I could think this is real is some sort of TOR network, but I'm suspicious. I'm equally suspicious of this 'key scrambler' - what keys is it 'scrambling'? Of course, it could be a name for a password manager? Anyhow, what software claims to be doing all this?

AVG has gone downhill recently, I'd recommend software listed by smargh above. This sounds like something is wrong your end, or maybe you're using extremely weak passwords?
