How to keep your computer safe—antivirus, updates and good habits

Computers are used daily for study, work, and entertainment. However, without proper protection, viruses, malware, and hackers can harm them. Regular use of antivirus programs, system updates, and good habits are essential to keep your computer safe.

Why Computer Security is Important

 Without security measures, computers can suffer from the following problems:

•       Loss of important files
•       Slow performance and crashes
•        Hackers: data theft
•        Malware, spyware and virus attacks
•        Unauthorized access to personal accounts

Therefore, computer security should always be taken seriously. It is always easier and cheaper to prevent damage caused by cyber threats than to fix them.

Use of antivirus software

Antivirus software is considered the first layer of protection. It scans files, detects malicious programs, and removes them before they cause damage. Popular antivirus software includes:

•        Avast
•        Norton
•        Instant Remedy
•        Kaspersky
•        bitdefender

Antivirus should be updated regularly so it can fight the latest threats. Real-time protection should also be enabled to stop attacks as soon as they are detected.

 

The Importance of System Updates

Companies release system updates to fix security issues and improve performance. When updates are ignored, hackers can exploit system vulnerabilities. Updating Windows, macOS, and Linux makes computers more secure and stable.

Browser, antivirus, and office software updates are equally important, as outdated applications are often a target for attackers. Automatic updates can be enabled to ensure no patches are missed.

 

Best Computer Security Habits

 

Use Strong Passwords—Passwords should contain numbers, letters, and symbols.

Enable two-factor authentication (2FA)—an additional layer of security that protects online accounts.

Avoid suspicious links—do not open unknown attachments or websites.

Enable firewall—firewalls prevent unauthorized access from outside the network.

Back up data—save important files to cloud storage or external drives.

Do not download unverified software—apps and programs should only be downloaded from trusted sources.

Log out of shared devices—always log out after using email or social media on a public computer.

 

Internet security practices

 

Since most threats come through the Internet, safe browsing is extremely important. Always keep an eye on secure websites (https://). Avoid using public Wi-Fi for banking or online shopping. Personal information such as phone numbers, OTPs, and credit card numbers should never be shared on unknown websites.

VPNs (Virtual Private Networks) can also be used when accessing the Internet over public networks, as they hide the IP address and protect browsing activity.

 

Physical security of the computer

 

Apart from online threats, physical security must also be maintained. Computers and laptops should be password-locked when not in use. Devices should not be left unattended in offices or schools. External devices such as USB drives should be scanned before use, as they may contain hidden viruses.

 

Conclusion

 

Computer security is extremely important in today's digital world. Antivirus maintenance, system updates, and security measures can keep your computer safe from most threats. By using strong passwords, safe browsing, and maintaining regular backups, data and devices remain secure and reliable. Taking a little precaution every day can prevent major problems in the future.
