Don’t enter any!
  •  Requests personal information?  Contains grammatical errors or misspellings?  How do they address you?  Is it too good to be true?  Have you checked the link?

  • Tip: A foolproof way to keep a virus from stealing your personal info - disconnect the network cable or turn off the Wi-Fi. THEN take action.
  •  Anti-virus can’t remove it  Computer is not unusable  Your files are missing  You must manually edit Windows  Your not absolutely sure your actions won’t make matters worse!
  • Home PC Security Part V
  •  External Hard Drive Backup  Windows Backup  Time Machine (Mac)  Cloud Backup  Carbonite  CrashPlan  File Sync Service (not really a backup)  Dropbox  Google Drive REGULAR BACKUP JUST DO IT.
  • Overwrites Current File Keeps Current File Keeps Current File & Adds File from Backup
  •   Backup saves/restores just YOUR data files Backup also creates a separate system image for restoring programs & Windows  Overwrites EVERYTHING when restored  Can only be used if the system repair disk was created
  •  Prevention begins and ends with you  Never use pirate websites for apps, music, movies or games (e.g. www.piratebay.com)  Loaded with adware/spyware/viruses  Opening these will infect your computer  Much of these sites content is illegal
  • R eceived Before? I nside Links? S ensible Message? K now sender? This email link delivers a Trojan Virus right to your computer

  •  Only login or send personal information to websites you know are encrypted  A website is encrypted when you see a “lock” symbol or https://  Beware of websites using encryption only on the login page
  •  Don't stay signed in to accounts  When you are done, log out Don’t do sensitive business on public WiFi  Don’t use the same password, vary it e.g. H1T0w3r! / P@$$w0rd!! / !P@inT3r!  Keep your browser(s) and plug-ins up-to-date  Keep Windows up to date 
  • 1. 2. 3. 4. 5. Regularly Backup of your files and data Use a Router, it hides your computer/network Make sure the Windows Firewall is enabled Use strong passwords on your Router and Computer Use anti-virus/anti-spyware to detect/remove malware And, practice safe surfing: if you aren’t sure, don’t click! Tip: By protecting your computer, hackers and Internet criminals “move on” to easier targets. Stay vigilant!
