General Internet & EMail Safety Tips:

 

Email Safety

  1. Don't click links in suspicious emails — Hover your mouse over them to preview the URL first and double check the spelling of domain names. Links should always start out with https:// followed by a name of a website that you recognize and intend to visit. Look for clues such as a slight misspelling of a domain name, or a foreign character. Examples might include a zero instead of an O, a 1 instead of an I, or a letter with an accent mark over it. This indicates trouble ahead. Instead of clicking a link, you can copy it to your clipboard and paste it to a text document where you can examine it carefully, or open a new tab and type it manually.
  2. Verify unexpected attachments Did the EMail come from an address that you recognize as being someone you know? You can always contact the sender through another method to confirm it came from them.
  3. Use strong, unique passwords for email accounts.
  4. Turn on two-factor authentication (2FA) — preferably using an app like Authy or Google Authenticator, especially on important financial related accounts and services.
  5. Check for spoofing — be wary of emails that look like they’re from friends or businesses but use odd email addresses.

General Internet Safety:

  1. Keep software updated — browser, OS, and apps.
  2. Use a reputable ad blocker to reduce exposure to malicious ads (e.g., uBlock Origin).
  3. Be cautious with free Wi-Fi — avoid logging into sensitive accounts on public networks unless you're using a VPN. Malicious people set up free WIFI that can be used to watch what you do and capture sensative information.
  4. Install antivirus software or enable built-in protections (like Windows Defender).
  5. Use secure HTTPS sites — most modern browsers warn if a site is unencrypted.

Passwords & Accounts:

  1. Use a password manager — Bitwarden or 1Password are good picks.
  2. Avoid reusing passwords — one breach can compromise many accounts.
  3. Watch for breached accounts — check your email on haveibeenpwned.com.

Behavior & Awareness:

  1. Slow down when reading urgent messages — scammers thrive on panic.
  2. Double-check URLs when logging in to services like banks or email.
  3. Don’t overshare on social media — personal info can be used for phishing or identity theft.

 


What do I do if my browser pops up a windows that says:

"Your PC is Infected!"

(or Similar)???

If you see a pop-up saying "Your PC is infected!", it's almost always a scare tactic — part of a tech support scam. Here's what to do immediately:


Do NOT:

  • Do not click anything on the pop-up (no "OK", "Cancel", "Close", or phone numbers).

  • Do not call any number or download anything it offers.

  • Do not enter personal information.


Do This Instead:

  1. Close the browser tab or window

    • On Windows: Ctrl + W or Alt + F4

    • On Mac: Cmd + W or Cmd + Q

  2. If the pop-up won't close:

    • Use Task Manager (Windows: Ctrl + Shift + Esc) or Force Quit (Mac: Cmd + Option + Esc)

    • End the browser task entirely.

    • If in doubt, shut down and restart your computer.
  3. Clear your browser cache and history

    • Also check if the browser re-opens the bad tab on restart and prevent it.

  4. Run a malware scan

    • Use Windows Defender, Malwarebytes Free, or another trusted scanner to make sure nothing slipped through.

  5. Restart your computer

    • Sometimes this clears temporary malicious scripts.


Going forward:

  • Install a pop-up blocker or use a secure browser like Brave or Firefox with enhanced tracking protection.

  • Make sure your OS, browser, and antivirus software are up to date.

  • Consider using a reputable DNS filter like NextDNS or Cloudflare for Families to block known scam domains.
