Website Hacked – Trojan Redirect?

I’m relatively inexperienced when it comes to managing my website, but it appears that my site, https://disneytouristblog.com has been hacked. When I attempt to access the site in IE, it attempts to redirect to another site, bee.pl. On my computer at home, Avast catches this as an attempted Trojan re-direct. At work, it stalls when attempting the redirect and nothing loads. On my wife’s computer, a pornographic website actually loaded the first two times she attempted to visit https://disneytouristblog.com last night, but since, she’s had no issues.

In both Firefox and Chrome, I have no issues loading the site. It loads as it normally did prior to this suspected hack.

I’ve read a few FAQs on what to do, and as a result I’ve changed my FTP and other passwords and killed my FTP connection. I’m also attempting to backup my site via a plugin that automatically backs up to Dropbox. Thus far that has been unsuccessful.

The other suggested steps for remedying this appear to be beyond my scope of knowledge. I am curious as to whether there’s a way for anyone to tell if the site has actually been hacked, or if there is potentially an issue on my host’s (Dreamhost) end, or something else? I really don’t want to proceed in tinkering with other aspects of my site that I could potentially damage if the issue lies elsewhere.

Thanks,
Tom
