Has any of you noticed that this only occured on that specific page of that specific thread?
There's simply an image, which was uploaded to s017.radikal.ru, shown on that page (
here to be exact). Chrome sees a GET request to s017.radikal.ru (to get that image), looks it up in its malware hosts database and sees that domain listed there. That does not mean that that specific image is malware, it means that somewhere on that domain, google found malware.
As far as I know, .PNG images cannot contain malware, but radikal.ru
can collect information about you. Many hosts do that though.
If you really don't trust it, you can simply block s017.radikal.ru. But it should be safe to just
proceed anyway. Nothing about stealing sensitive information and fishing btw, that's nonsense.
