How to Stay Safe Online
Here are 10 basic security tips to help you avoid malware and protect your devices.
Use a good antivirus and keep it up-to-date
It's essential to use a quality antivirus to stay ahead of cyber threats. Free solutions are available for all devices that protect against malware and viruses.
Keep software and operating systems up-to-date
Software companies regularly update platforms to fix vulnerabilities. Update your operating system, browsers, and apps whenever prompted.
Be careful when installing programs and apps
Pay close attention to installation options and uncheck agreements for toolbars and add-ons. Take care in every stage of the process.
Install an ad blocker
Advertisements can sometimes spread malware. Use ad blockers that stop malicious ads, images, and other content that antivirus might miss.
Be careful what you download
Research before downloading freeware or apps that might carry hidden malware. Be especially cautious with torrent files.
Be alert for people trying to trick you
Stay vigilant against phishing and social engineering. Remember that banks never ask for passwords, and familiar names don't make messages trustworthy.
Back up your data
Back up frequently and verify that backups can be restored. Use external drives disconnected from your computer or trusted cloud services.
Choose strong passwords
Use unique passwords for all accounts. Avoid personal information and enable two-factor authentication (2FA) when possible.
Be careful where you click
Exercise caution with links or attachments from unknown sources. These could contain malware or phishing scams.
Don't use pirated software
Avoid key generators, file sharing programs, and cracked software. These are often compromised with malware or crypto-miners.
