Re: Well lets name them....
just how wrong can one post be?
"Screening Detection" is trivially simple - even an advertising "executive" would be able to work out that a banner Ad is too big - that it's got something extra. They charge by the size of the data transmitted, and everyone (except malware providers) do all they can to minimise the size of their submitted code.
Any credible online advertising ageny won't be using anything like "AVG" - they'll actually have people who can examine the file in detail and will find the embedded code. The miscreants in this instance have identified and used Agencies with the technical know-how of "mark 63"
