Chrome is giving me the generic warning:
Warning: Visiting this site may harm your computer! The website at www.#*$!.com contains elements from the site YYYY.com, which appears to host malware – software that can hurt your computer or otherwise operate without your consent. Just visiting a site that contains malware can infect your computer. For detailed information about the problems with these elements, visit the Google Safe Browsing diagnostic page for YYYY.com. Learn more about how to protect yourself from harmful software online. I understand that visiting this site may harm my computer.
HOWEVER, own safebrowing diagnostics page says everything is FINE and has always been fine. [google.com...]
The site YYYY.com its complaining about ALSO checks out fine by google.
Im certain my site has not been hacked, checked everything. Seems like a really bad false positive by Google.
What can I do? This is gonna kill my traffic if its widespread.

Also should site YYYY.com be displaying content on your page? If it's an advertiser and the advertiser's site does not display the same warning then the dodgy stuff might only be in the adverts they host for third parties.

I'd review every bit of 3rd party stuff you have installed on your site. If you're running some ad network or traffic tracker in your site, it's possible one of them has been infiltrated. What I see happen often is an ad network randomly serving up something from the network that's malware instead of an ad.

Try a Google site: search on your site, and see if any of the individual pages are flagged with the warning.
Occasionally, only part of a site is flagged, such as /blog/, while the rest of the site remained unflagged. When that happens, the Safebrowsing report for the main site can show nothing is wrong, while the report for its /blog/ portion shows the malware info.
You might also try the Safebrowsing report for both www. and non-www forms. It used to be that the two could sometimes show different info, although I think they got that resolved a long time ago.
Also try clicking to your site from a Google search result. Perhaps malware is testing the referer string, and only appearing when it's a search engine.
Google Webmaster Tools might have additional useful information, including the Fetch As Googlebot feature.
False positives in the Google Safe Browsing database are rare.
Intermittent problems are the hardest to track down. Advertising can cause intermittent problems because ads get rotated.
