I don't know if anyone can help shed some light on an issue I've got with a website I created for a client. ttadventure.co.uk is flagging an Exploit Blackhole alert in AVG, but before you stop reading and start typing a response about obfuscated code and iframes bear in mind I've already taken these steps.
The other oddity is that I cannot replicate this problem. It's only a handful of people who have reported this back to me. I've installed AVG Free 2012 on a clean machine with Windows XP and all the updates applied and IE8 on it but to no avail. Website behaves and there are no alerts.
I've also installed Chrome because a friend of mine tried the site and said it flagged the Blackhole error but they were using Chrome instead of IE.
I've drawn a blank on this and cannot understand why some machines would alert and others won't.
Any thoughts or suggestions would be greatly appreciated.
Had same issue with this. Several people reported a black hole exploit warning when attempting to browse our site. No light provided by online AVG support. At least one report was from an AVG user, but I could not replicate problem. My paid-up up to date AVG installation did not report a problem, and neither did the Google site diagnostic tool. I wiped site and reloaded, and my free AVG user colleague informed me he could now browse site as normal, without any warning messages. I really don't know what to make of this, anyone any ideas ?
