Google Adsense serving malware-infected ads (productforums.google.com)

Has anybody else had trouble with Google Adsense serving infected ads recently? I was investigating reports from a user of my site who claimed he got forwarded to the "softwareupdatelp*com" malware as soon as the page loaded.

While trying to find the reason I came across this, which seems to confirm that this might be coming from Google Adsense.
