To Pat Bitton
You say "We're also continuing to gather data, and work with webmasters and analytics folks, and we still enable those webmasters who want to filter our requests out of their results to do so". Can you please explain this comment in more detail? I'd love to work with you, so give me a Web site to look at, or an e-mail address to start with. And how exactly can I filter if you look exactly like IE6.
By the way, my company's AVG license (25 user) has just expired and we're installing an alternative product. This is directly due to the fact that you are wasting processing time and bandwidth on our customers' Web sites. I did e-mail your sales e-mail address before we took this decision to invite your feedback, but I was ignored.
You fail to realise that some of your customers are also web hosts. And ignoring your customers is just plain rude.
It is not acceptable to "break eggs" to make omellettes when you don't own the bloody eggs!
You also haven't answered the question that's been posed time and time again when this story has been posted: "why don't you scan on demand instead of in advance" ?
Or the question of "hmmm.... how a malicious host can fool link scanner". If that were me (and I'm not the first to say so), I'd do it like this - don't put out any malware on the first visit from an IP address to a page in case link scanner identifies me, I'll put it out a bit later when the user actually visits. Or perhaps use a delayed or user initiated JavaScript redirect that Link Scanner won't pick up, to then go to another page stuffed full of malware.
Not only are you hurting the hosting industry and your customers, but your solution is inept.
Frankly, AVG are swimming against the tide. When will you listen? Turn this crap off.
