Firefox lets me go there, privoxy has no problem, and neither do any of the other programs I have to block stuff and/or warn me. I've seen that at other sites but haven't ever figured out why exactly. Sometimes if I just try again the warning is gone, other times it's not. I've wondered if it has something to do with the ISP somehow.
I'm very unlikely to pick up a virus, they're written almost exclusively for MicroSoft. I use penguin power.
