Search your pages for links to flagged sites

If your site can still be flagged for outlinking directly to another site that has badware on it (which, as mentioned earlier, I am not sure is still the case), only one-hop links count. If you link to a site that links to a site that has badware, that does not cause a flag.

Having a large number of outlinks makes you especially vulnerable. If you link to 1000 other sites, what are the chances that they all manage to stay clean all the time?

To investigate, make a list of all the sites you link to. For each one:

* In any Google search box, enter site:thatsite.com, or
* Look it up in the StopBadware Clearinghouse database

If any of the site's pages have the "This site may harm your computer" warning, you may be flagged for linking to them. Or they may be flagged for linking to you, if they do. There's no way to tell which it is. If you have a good relationship with the other site, tell them they've been flagged. They might not know about it.
