Internet Safety
• Protect your identity
– Do NOT give away your Name, Address,
phone / credit card / bank numbers, etc.
– Use fake names, false info
• Why?
– The web page may not be secure, someone
else may get this info
Email: Spam, Virus
• When you give away your email, you may
get
– Spam = junk mail = stuff you don’t want
• Ads = “Look at this! Buy me! Try this game too!”
• Use Spam Filters to block them
– Viruses = bad files that do bad things to your
computer
• Usually attached .exe files – DO NOT OPEN
• Can get from downloads – be careful!
• (I keep multiple emails)
Passwords
• Don’t tell anyone!
• Make it hard for others to guess
but easy for you to remember
– Don’t use your name or birthday
– Don’t use words
– Longer = better
– Use numbers, symbols like !@#$%^
– Case sensitive? ABC abc

search your e-mail.

pretending to be 18 year-old girl

pages, e-mail, QQ/ wechat – others may
see it.
