Cybersecurity is no longer a nice-to-have; it’s a must in 2025. It’s an absolute must. Protect your computer and personal information from hackers by using these easy but effective tips.
Don’t wait until it’s too late if you think your computer has been hacked. AM Wireless in Scarborough, Toronto, is a reputable local repair shop that specializes in security and professional diagnostics.
At AM Wireless, we repair computers and laptops every day that have been compromised by malware or hackers. Here’s how you can stay safe in 2025 and avoid the same mistakes many people make.
1. Use Strong Passwords and Two-Factor Authentication (2FA)
Weak passwords remain one of the most common ways hackers gain access to computers and accounts. Use a combination of letters, numbers, and symbols for each login and never reuse the same password twice.
Enable two-factor authentication (2FA) for your email, banking, and social media accounts to enhance security. It adds an extra layer of security by requiring a second code or device approval before access. Password managers like Bitwarden or 1Password can help you generate and securely store unique passwords.
2. Keep Your Software and System Updated
Many cyberattacks exploit old software vulnerabilities. Enable automatic updates for your operating system (Windows, macOS, or Linux) and regularly update your browsers, drivers, and security apps.
If you use a router at home or in the office, don’t forget to update its firmware as well. Outdated firmware can make your entire network vulnerable. At AM Wireless, we always check for the latest security patches when servicing customer computers.
3. Secure Your Home Wi-Fi Network
Your home Wi-Fi is the gateway to your devices. Hackers can easily breach networks using default passwords or weak encryption.
Update your router’s default login details and set up a strong password for Wi-Fi access. Use WPA3 encryption and avoid sharing your main network with guests — instead, create a separate guest network. Disable remote management unless necessary, and update the router firmware regularly.
4. Install Reliable Antivirus and Anti-Malware Tools
Even experienced users can accidentally download malware or spyware. A trusted antivirus acts as your first line of defense.
Choose well-rated solutions such as Bitdefender, Norton 360, Kaspersky, or Malwarebytes. Enable real-time protection and schedule automatic weekly scans. Pair your antivirus with a firewall to block suspicious connections and prevent unauthorized access to your computer.
5. Beware of Phishing and Fake Websites
Phishing emails and fake websites are becoming increasingly difficult to spot. Cybercriminals use AI to make scam messages look authentic.
Be cautious of emails or texts that create a sense of urgency or request personal information. Always check the sender’s address and hover over links to see where they really lead. If you’re unsure about a message, please contact the organization directly through their official website or customer service number.
6. Backup Your Data Regularly
No security system is perfect. Accidents, ransomware, or hardware failure can still happen. Backing up your important data ensures you don’t lose it forever.
Utilize a combination of cloud storage and external hard drives for offline storage. Follow the 3-2-1 rule: keep three copies of your data on two different types of storage, with one copy stored off-site. Ensure your backups are encrypted and test them regularly to confirm they function properly.
7. Use a VPN for Safer Online Browsing
If you connect to public Wi-Fi in cafés, airports, or libraries around Toronto, use a Virtual Private Network (VPN). A VPN encrypts your internet traffic and protects your data from being intercepted by hackers.
Select a reputable VPN service that offers robust encryption and a strict no-logs policy. Avoid free VPNs as they may track your activity or sell your data.
8. Limit App Permissions and Protect Your Privacy
Review which apps and software have access to your data. Some programs collect more information than necessary, increasing your risk of exposure.
Regularly check app permissions on your computer and browser—restrict access to your camera, microphone, or location for apps that don’t require it. Clear your browsing data and cookies to prevent tracking and use private browsing modes when shopping or banking online.
9. Stay Informed About Cybersecurity Trends
Hackers constantly change their tactics, so it’s essential to stay up-to-date. Follow trusted tech blogs, cybersecurity forums, and official sources, such as Microsoft or Apple’s security pages, for news on the latest threats.
If you notice your computer acting strangely — running slowly, opening random pop-ups, or crashing frequently — visit AM Wireless for a comprehensive security check and virus removal service.
10. Build a Multi-Layer Defense System
For optimal protection, utilize multiple layers of security. Combine strong passwords, 2FA, antivirus, firewall, VPN, and regular backups. This way, if one layer fails, others will still protect you.
Encrypt your hard drive (using BitLocker on Windows or FileVault on Mac) to protect your data even if your device is stolen. Keep sensitive files in secure folders and use trusted cloud storage with multi-factor authentication.
