Hi. New to iPad and iOS. Do I need to run anything like Avast or Malwarebytes to keep the nasties at bay on this device? I am a multi-platformist at heart, but some things sure seem cumbersome and even near impossible on an iPad (web design, etc.), which is too bad because this little toy is fun. I still really miss certain things about my 10" netbook (multiple window views, etc.; so it's still tucked behind the sofa pillow LOL) but I'm willing to keep playing. Any advice, shortcuts, etc., always appreciated.
