The arrow of time

It's well known and propagated that in the last hour or so Google has been flagging everything as a potential security risk / malware carrying site. I won't go into philosphy of the whole thing, just want to share an observation: I've noticed it myself but on a result from Wikipedia and I just ignored it - "no way is Wikipedia spreading malware". Only later I confirmed  that it's Google's problem (on other forums, blogs, etc). In this particular case, had Wikipedia really been taken over, it wouldn't have helped me a bit. I was ready to trust that it's a Google or FF bug rather than Wikipedia's. And I'd probably do the same next time.
