Tips on How to Stay Safe Even With the Free Antivirus
Here is the truth: Even with the best free antivirus software, it’s not enough to fully protect you if you don’t take precautions online. Think of it like wearing a safety belt, but driving with your eyes closed. Your actions matter just as much as the tools you use.
Here are some simple but effective ways to stay safer:
Update your software regularly
Ensure you update the systems and apps as often as possible. These updates are handy, given that they help in fixing any security flaws that hackers could be actively trying to explore. To make it easier and timely, we recommend setting auto-updates.
Watch out for the pop-up and sketchy emails
Be careful before you click a link in an email you don’t recognize. Be wary of pop-ups and messages that say “click to win an iPhone 16.” That’s bait.
Use a stronger password
Reusing the same password across different accounts can be risky. If one account is hacked, the rest become vulnerable. You can use a mix of letters, symbols, and numbers, or better yet, try a password manager. It keeps your credentials safe.
Consider a second-opinion scanner
Even with a great free antivirus running, you can occasionally scan your system with other tools. They can help pick up threats that one antivirus software might have missed.
Enable two-factor authentication (2FA)
Having an additional two-factor authentication is great to block a hacker if they are able to guess your password.
