Cybersecurity is a key factor for businesses of all sizes. With the broad computer interconnections, malicious actors are increasingly seeking unauthorized access to your sensitive data. Online predators tend to prey on personal data for political and financial gains, espionage, data extortion, and theft. Such actors achieve their wicked goals through malware, ransomware, viruses, Trojan horse, adware, and spyware. So, how can you secure your computer?
How to Protect Your Computer From Different Cybercrimes
Physically protecting your PC is a basic step when you want to qualify as being cyber-smart. That means never leaving the device unattended and disabling Wi-Fi, Bluetooth, and screen-lock notifications. If you lose your gadget to theft, it may end up in the hands of hackers, who might steal your identity and bring about considerable harm.
Physical security is as good as taking the following technical security measures.
Using strong and unique passwords is the simplest, most affordable, and first line of defense against invasion. To make your device more secure, incorporate multi-factor authentication and regularly change your passwords.
Many illegitimate sites containing malware now exist, yet most web browsers lack default security settings. Therefore, activate the HTTPS Everywhere extension and choose a modern browser with increased security. It is critical to block unsafe websites and malicious codes from operating on your computer. Plus, when you must get add-ons or plugins, get them from trusted sources.
Tip: Do not open suspicious attachments or links in messages, emails, adverts, tweets, or posts. These are phishing baits to fake websites.
Secure Network Connections
When using devices like routers that permit configurations, the Secure Sockets Layer (SSL) helps to harden your devices and protect all the data you send and receive over the internet. The Virtual Private Network (VPN) also encrypts your web traffic.
Although most operating systems have built-in firewalls, you must enable and configure the feature in the OS and home router. Additionally, enhance its security using strong passwords to prevent any disabling threats by hackers.
OS Regular Updates
The core of software and OS updates is to remove redundant features that form a cyber-attack risk while also improving the security and stability of the machine. So, once installed, turn on automatic updates and adjust the security and privacy settings of your web browser and all the apps you frequently use, keeping them up-to-date.

Avoid Pirated Materials
Shun using USBs and other external devices from unknown sources since they may contain viruses and malware. On the same note, only download movies and resources from trusted sources.
Follow the Principle of Least Privilege
This principle highlights the need for two accounts; one for daily activities and the second, an admin account to give you the privileges of removing or installing a program and modifying your computer settings. Such a plan limits the attacks on the logged-in account.
Remove junk software: The less the volume of software installations, the lesser the risks of an attack. Once you’ve confirmed that the software’s uninstall is safe, remove all unused programs.
Backup: Use cloud and external hard drives to store copies of your files for easy retrieval in the event cyberattacks are successfully launched.
Professional email: To close the email gateway for hackers, use an encrypted one with MFA, digital signatures, instant messaging, and document storage and management tool.
