Safari 8.0.3. (10600.3.18) POP UPS embedded in posts!!

You picked up a unwanted spam plug in.

Adblock may help stop them.

I would switch to firefox and add the flash plug in if needed, for videos.

I watch the videos on youtube on firefox,  with no problems on my imac.

Use the html5 option on youtube.

I got that on Firefox a few weeks ago, though I didn't have any pictures of girls popping up. (now I feel cheated...)

On Firefox, I just had to "reset" it by going to their website and clicking on a link. From there, it took about a minute for it to do whatever it did.

Don't know if there's a similar action to take with Safari. We only use that browser for a few sites that detect what browser we are using and require it.

Incidentally, I've had this happen a few times in the past month, and it seems to line up pretty nicely with my daughter using the computer to play some online games. If it persists, I'll have to keep a closer eye as to exactly what those sites are putting on our machine.

Hope this helps,

Eric,

it appears to be a Safari feature called "spotlight suggestions" Apparently, it's not spotlighting content that you desire.

Look in the Safari settings to disable it. or at least some feature like it that was intended to be helpful.

not an Apple guy, but it should be able to be turned off.

Update:

You inadvertently have some add-on or adware. Look at the adware removal guide
