AV detection of malware during real-time web browsing (cache, java, etc)? Virus Guy 04-12-2006

Has anyone ever had the experience that their AV software has alerted
them to *something*, in real time, as you were accessing a web site
(ie surfing the net)? Perhaps the *something* was found in the
browser or java cache, or a malicious plug-in (direct-x, etc)?

I'm talking real-time here, not something that was detected as a
result of a scheduled or manual scan.

I'm not talking about a browser re-direct, pop-up, or a screwy/invalid
certificate, or a cookie. I'm talking bona-fide browser exploit,
virus, trojan, worm, jpeg/wmf thing, etc, that results in code
download/execution, privledge elevation, etc.

Yes, several times. Because of the work I do I have to go quite often to
very dubious sites. Several times Avast! asked permission to cut a
connection because some site tried to install some trojan, without
clicking on anything, just by visiting the site. This were (of course)
mainly pornsites of the worst kind.

I'll ask you the same question I just asked David. Is this just with
IE, and with what IE security settings?

What happens when you don't use IE, or disable scripting and axtivex
in IE? Do you still get the alerts?
