An anonymous reader writes "Google's malware checker on Sunday has for some reason detected TwitPic.com as a threat. As a result, if you try to access the site from Google.com using any browser, you'll get a malware warning. Furthermore, if you use Google Chrome, TwitPic.com pages as well as Twitter pages that rely on the service will result in a blocking prompt as well. To try this for yourself, head to Google.com, search for TwitPic, and click on any link on twitpic.com. If you're using Google Chrome, just try to go to TwitPic.com or visit a Twitter page that relies on the service (many use TwitPic images in profile pages), such as Twitter.com/TwitPic. Direct inks to TwitPic images, however, appear to work fine, and embedded TwitPic images load on Twitter as well."
