This is further reason to block ALL ADS forever.

A reader comment on Slashdot's HeadLines for 12 November 2014 made this

" Cryptolocker wiped out tens of thousands of projects, and
" thousands of businesses; criminals were not prosecuted because
" files were encrypted on police file-shares, and people died
" because the same happened to hospitals. This is why Putin

" not as virulent.
" Where did it come from? Yahoo's web advertising network which
" is well-documented.

verifies the claim; followings items from the first page of hits:

sites) do nothing to vet the ad sites linked from their pages. They just
want the money and are unwilling to make sure that their advertisers are

Before I began using AdBlock I was using a hosts file that blocked out
thousands of questionable sites. I like AdBlock better. What's curious to
me is that Google RECOMMENDS AdBlock! It would seem counter-productive for
them to do so, but what the heck.

I don't know if Yahoo is any more the culprit than other portals. When
Shaun White won in the winter Olympics, I went to Google's video search to
find a video of his win. The 3rd image over from the left showed what
looked like the video. I clicked on it and the site told me that I had to
install a special viewer. Without thinking I clicked a link and immediately
my computer began acting up. Some malware began putting a link to a Polish
malware site on the end of EVERY text and html file on my computer! So, you
can't even trust Google's results 100%. Google did take off the link about
