I only access with Firefox, and I have NOT gotten any virus alerts. My anti-virus and firewall software is kept up-to-date, so if it's there I would expect to get an alert.
One nice feature I've found with Firefox is a plug-in which lets the user control all Java scripting. I can allow scripting for BDSM Library without allowing it for the ads on the pages. I can also allow cookies for the library but block them for the advertisers.
And no, I don't own stock!
