Check your HTML code for suspicious <script> and <iframe> blocks. If you find any, they could have been added by a virus on your computer or by someone who sniffed your FTP password and changed the files on the FTP server.

It might be you did not properly sanitize input you output and someone exploited this to inject malicious code to your site. This could be through URL params or forms for example or when including content from other servers, like ad rotation banners.
