The Register reports that anti-virus company AVG is sending out fake web traffic from its customer's IPs as they surf the web. They're identifying their bot as Internet Explorer 6. AVG claims they're doing this because they malware pages would just block or spoof their bot if it used a proper user agent.
There's a bit of outrage in some sectors, because this is driving up traffic and skewing people's logging and analysis. Some are outright blocking IE6, or redirecting the traffic to AVG's site. Of course, anyone who actually uses IE6 is being caught up in this along with the bot.
I think this might be the actual goal, and if so, I tip my hat to you grisoft, you sneaky bastards.
