In December, I got a virus likely from such
auto-play
videos.
Symptom and Solution. On Windows, kept getting auto-started instances program iexplore.exe running. Virus scanning for days didn't solve the problem. Finally a Windows system restore back to November or so did solve the problem.
Larger Solution. Of course, for each video clip on a Web page, Firefox and Flash keep saying that Flash is vulnerable.
No joke. Then they refuse to play the video unless I
confirm by clicking three times. So, great! Now those
videos no longer auto-play.
Of course, for this benefit, I am still running version
12 or some such of Flash. So, after 12 versions, Flash
still has bugs? So, I'm going to believe that 13 is such
a lucky number that finally version 13 will be safe?
Nope! So, I will stay with version 12 and, thus,
block the auto-play videos. When I do want to play a
video, it will be a significant video from a
respected source and, thus, likely safe; I have to
doubt that version 13 would be much safer.
There are other such frustrations at Web sites that
still cause me to do what you do -- leave!
