Below is a list of tips to help you protect your online activities:

1. Use a secure connection: Use HTTPS instead of HTTP when possible. HTTPS encrypts the data being transmitted between your computer and the destination server, which prevents third parties from accessing the data.
2. Log out of accounts: Always log out of online accounts when you're done, and don't save passwords on the computer.
3. Be aware of tracking systems: Be aware of tracking systems such as cookies, pixel trackers, and web bugs, which are commonly used by websites to record visitors' activities. Disable tracking features if available.
4. Be careful when opening emails: Be cautious when opening emails from unknown sources or attachments. It is also important to scan your emails for viruses and malicious software.
5. Choose a complex password: Choose a password that is difficult to guess, and change it frequently. It is also important to never share passwords with anyone.
