My Macbook updated itself to Firefox 10.0 the other day & ever since then when I try to login to a specific site I get the above error message.

The website admins say it is not coming from them, what is it & how do I get rid of it?

Thanks

Their browser detection script is out of date. The warning seems to come from this file: http://virus.info/api/load/file/js , specifically, the badBrowser() function.

It's checking for "Firefox/1", which it finds as part of "Firefox/10".

Perhaps point them towards this blog post: http://hacks.mozilla.org/2012/01/firefox-goes-2-digit-time-to-check-your-ua-sniffing-scripts/
