Possible to infect others with virus if you own a blog?

Hi, I was wondering if it was possible to send a virus to people who have commented on your blog, or just knowing their ip. Because I posted a condescending comment on someone's blog the other night and today I suddenly get a trojan and my java infected out of NO WHERE.

Is it technically possible? Yes. However, highly unlikely.

It would require some advanced knowledge, tools, and patience behind the keyboard. In other words, they really would have to know what they're doing, and you really would have had to make them mad. And even then they could be blocked by a router, firewall, etc. Most likely a coincidence.
