Whether ie or any browser is secure or not doesn't matter if you go to giveawayoftheday.com -- only half teasing, if you're not going setting up a secure connection with a site [e.g. signing into Amazon to buy your videos], & you're not opening a web page containing whatever exploits, it's kind of irrelevant. You don't have to like or use ie for anything else but I fail to see any big problems using it as part of Leawo's app to grab something from YouTube.
In the US & I think much of the EU you can view legally streamed movies from services like Amazon or NetFlix or Hulu Plus etc. [not sure the names of whatever EU services], but they generally use some sort of DRM making sure you use their software &/or plug-ins, can't make a copy & so on -- otherwise people use bit torrent to download whatever file(s). If someone wanted to view an illegally streamed movie in an app like Leawo's Video Accelerator, odds are overwhelming I think it's gonna be from a site in China, where Homeland Security can't walk in a seize their servers. So yeah, if Video Accelerator has links to movie streaming sites, those sites are very likely gonna be in China.
That said, while efforts may be underway to control what you see on-line, they're solely focused on making sure you can't see something -- not the other way around. Unless you've got malware operating on your system, unless it's been hacked into etc., no one forces you to download or look at anything. As graylox put it: "It's up to you what the software does for you."
Finally, when anyone pairs the words scary & pirate in the same paragraph, *IMO* they're either misleading or have been mislead. Watch the latest Pirates of the Caribbean movie, or read the news 'bout areas of the world where piracy is more common, or look in the history books -- when you see the words pirate or piracy connected with content or software someone's making an editorial comment. I mean I've yet to see or hear of anyone [even allegedly] connected with illegal content storming a boat or ship, taking hostages & killing people. [Note that while I did read of Kim Dotcom putting a tank in his yard, I also believe I read it was inflatable.] I'm Not saying I agree or disagree with illegal use, but only pointing out that when the word piracy is used in that context it's not an objective conversation, & should be treated the same way as someone making a pitch to sell you an illegal copy of whatever, be it a Rolex, Windows, or a copy of that Pirates of the Caribbean movie I just mentioned. :)
