Basic security on computers and cell phones

Computer and mobile phone security is an increasingly relevant topic in the digital age, as we rely more and more on electronic devices for work, communication, and storing important information. However, this dependence also comes with certain risks related to digital security.

For this reason, it is important to learn how to protect our devices from cyberattacks, both computers and mobile phones. We must know how to avoid scams, what actions to take if our devices are stolen, or if important files are deleted. This is not just about protecting our devices but also about safeguarding our personal information, accounts, and online interactions. By following preventive practices and using security tools correctly, we can significantly reduce risks and enjoy a safer digital experience.

First of all, to avoid viruses, it is essential to have a trustworthy antivirus software and keep it always updated, as this will help detect potential threats before they can infect your electronic device.

Additionally, it is advisable to keep the operating system up to date, as developers constantly release security patches that fix vulnerabilities attackers might exploit. Another crucial step to always keep in mind is to never open emails, links, or attachments from unknown sources, as many viruses spread this way, so staying alert is key. Also, avoid downloading apps from unofficial sources; always opt to get them from trusted stores like the App Store or Google Play. Otherwise, you increase the risk of installing malicious software.

Online scams are another growing risk. Offers that seem too good to be true are red flags, as they are often designed to steal your personal or financial information.

Make sure the websites you visit are trustworthy before entering your data—check that the address starts with "https://" and that there is a padlock icon in the address bar indicating a secure site. Additionally, enabling two-step authentication on your accounts provides extra security, making it much harder for someone to access your data even if they steal your password.

Now, if your phone or laptop gets stolen, it is crucial to act quickly to minimize damage.

The first thing you should do is remotely lock the device. For mobile phones, tools like "Find My Device" (Android) or "Find My iPhone" (Apple) allow you to lock the phone and, in some cases, erase all information remotely. Then, inform your service provider to block your line, preventing unauthorized use. Also, change your passwords immediately, especially if you had banking apps or social media accounts logged in. Similarly, laptops also have tools like "Find My Mac" or "Find My Device" (Windows). Additionally, it is crucial to report the theft to authorities and your service provider if you have theft protection coverage.

Finally, recovering accidentally deleted files remains one of the most common concerns.

If you delete a file by mistake, the first thing to do is check the trash bin or the "recently deleted" folder, as many devices and operating systems temporarily store files there before permanently deleting them, giving you a second chance to recover them. If the file is not there, programs like Recuva (for Windows) or Disk Drill (for Mac and Windows) can help you find and restore deleted files, as long as the disk sectors have not been overwritten. If you have automatic backups configured, such as Google Drive or iCloud, you can also restore files from there.

In summary, the key to keeping your devices and personal data secure lies in taking precautions, such as installing antivirus software, keeping systems updated, being cautious with suspicious emails and links, and enabling two-step authentication as an additional security measure.
