I went to this weird site for fun named
(DO NOT VISIT THIS SITE UNLESS YOU HAVE A VIRTUAL MACHINE)
virus4u dot com
This site is extremely malicious. On a school computer, the audio screamed "Alert Alert! Virus detected!" Until I forced shut it down. On androids (LUCKY) they simply show you a scam "Win an iPhone X for only 1$"!
After I went on the malicious site on my iPad, it said that my iPad was LOCKED and I had to contact "Apple Thec Support". I am aware this is scam, but my iPad was freezing, plus when I tried closing the site, It would not close, and I also could not slide to power down my iPad.
After I forced shutdown my iPad (holding power + home), everything is now normal.
However, I am very puzzled. How the heck can a website make so I cannot slide to power off, and freeze my iPad, even after clicking home button!? I couldn't swipe or click. I need more explanation on this!

This is not anything about a virus removal, also not sure if this should be here or on Information Security.
