If you see an email accusing you of breaking the law, that your computer is infected, they have “information” about you, or just plain weird delete it immediately.
There has been a big spike in extortion emails going around recently and it is just getting worse.
If you get a call, email, or popup saying that they are “Microsoft” the “IRS”, etc… it is always a scam. These companies would never call you.
It does not matter if you have a Mac or PC, Android or Iphone. You may see them on all platforms.
