The last two or so times I logged in via chrome I got a 'potential malware' warning which I assume comes from an ad linked on the page [either that or my computer is virus ridden, but I haven't got the error elsewhere.]
I didn't get a screen shot but I copied the text in case it helps identify the culprit:
Warning: Something's Not Right Here!www.badmovies.org
contains content from animated-views.com, a site known to distribute malware. Your computer might catch a virus if you visit this site.
Google has found that malicious software may be installed onto your computer if you proceed. If you've visited this site in the past or you trust this site, it's possible that it has just recently been compromised by a hacker. You should not proceed. Why not try again tomorrow or go somewhere else?
We have already notified animated-views.com that we found malware on the site. For more about the problems found on animated-views.com, visit the Google Safe Browsing diagnostic page.
A quick jump around the site got me to that page about three times when clicking different forum threads for a few minutes, so I'm pretty sure its one of the ads.
