I just wanted to tell everyone to be careful. Here is the message I sent to Livejournal support yesterday. It's short, so it's not under a cut.

I thought you should be aware that there is a serious problem with some of the ads you are running. I cannot say which ones, but I had a horrible experience while at work. I went to my livejournal and clicked on a friend's page, and, without my choice or knowledge, malware was loaded onto the library PC. This was at my workplace, and it rendered the computer - a PC we use to send jobs to the printer for our patrons, etc - absolutely unusable. The program that downloaded calls itself "Your PC Protector". It's nasty.

I thought you should know that your site was being used in this way. We users tend to trust the site and don't expect attacks when visiting pages we've viewed before! I'm seriously considering moving my content to another journalling site if Livejournal cannot protect its users from malware attacks like this one.

Thanks. I do hope you can do something to fix this problem.
