Computer viruses and malware are constant threats that can damage files, corrupt software, steal personal information, and even render computers unusable. As computer users, we must be vigilant in protecting our devices from these cyberattacks. This comprehensive guide will outline all the necessary precautions I take to safeguard my computer.
Use Antivirus and Anti-Malware Software
The first line of defense is to install reputable antivirus and anti-malware software. I use Bitdefender Antivirus Plus which provides real-time scanning and protection against all types of malware including ransomware, rootkits, spyware, adware, and more. I schedule weekly full system scans to detect dormant threats. The software has low system resource usage allowing my computer to run fast. I also ensure the software auto-updates its virus definitions database daily to protect against the latest threats.
For additional security, I use the anti-malware program Malwarebytes to perform periodic scans. This aids in detecting deeply embedded malware that standard antivirus software may miss. I run Malwarebytes scans at least twice a month for thorough cleaning. The combination of antivirus and anti-malware keeps my system locked down tight.
Practice Safe Browsing Habits
I adhere to safe browsing practices to avoid infections from malicious websites. I avoid suspicious looking websites altogether and refrain from downloading random files or programs. I have disabled auto-download prompts in my browser settings to prevent inadvertent malware downloads.
I utilize the Brave browser which blocks ads and trackers that could contain viruses. I also use the browser’s built-in shields up feature to prevent sites from deploying malicious scripts. For sensitive transactions like online banking and shopping, I leverage Brave’s Private Window with Tor integration to enhance security.
Keep Software Updated
I ensure all the programs and operating system on my computer are updated regularly. Software companies constantly release patches to fix vulnerabilities that could be exploited by malware. I have enabled automatic updates wherever possible to receive the latest upgrades as soon as they become available.
For applications like Adobe Flash, Reader, Shockwave etc, I manually check for updates weekly. I also regularly check for Windows security updates using the Windows Update tool to maintain an optimal state of protection.
Use Strong Passwords
I use long, complex alphanumeric passwords across all accounts and services to prevent unauthorized access. My passwords utilize upper and lowercase letters, numbers, and symbols for maximum strength. I refrain from using personal information or common words/phrases that could be easily guessed.
I leverage a password manager like LastPass to generate and store my passwords securely instead of reusing the same passwords. The password manager feature also helps me log into sites and apps without exposing my passwords. I have also enabled two-factor authentication (2FA) on important accounts for an added layer of login security.
Avoid Clicking Links in Emails
Cybercriminals often use email phishing tactics to spread malware and steal credentials. I avoid blindly clicking on links or downloading attachments in emails, especially from unfamiliar senders. Even if the email appears to be from a legitimate source, I manually navigate to the site through the browser if I need to access links sent in emails.
I also check that email addresses of senders are valid and be wary of spelling errors or substitutions in addresses. Enabling the “show original” option in my mail client allows verifying actual underlying email addresses. These habits prevent me from falling victim to phishing emails trying to infect my system or capture my login information.
Use a Firewall
I keep my computer protected behind a firewall to prevent unauthorized network access which could enable malware installation or hacking. The Windows firewall coupled with my router’s SPI firewall provide inbound and outbound filtering to block malicious traffic. I have the firewalls configured to allow connections only to trusted applications and services.
For heightened protection, I utilize ZoneAlarm as an additional software firewall on my PC. Its real-time monitoring capabilities ensure only legitimate programs are communicating on my system’s network interfaces. The firewall actively alerts me about suspicious connections for review.
Avoid Pirated/Cracked Software
I refrain from using illegal pirated or cracked software. Such software often contains malware payloads intentionally bundled alongside installers to infect computers. The malware allows cybercriminals to remotely control computers for nefarious purposes. I only use genuine licensed software from trusted vendors to stay protected.
If certain paid software is expensive, I try alternatives like open source or freeware options. For expensive productivity tools, I use legal discounted licensing from my company or educational institution. Paying for legitimate software ensures I receive clean installation files without malware.
Make Regular Backups
I maintain backups of critical data on an external hard drive as well as cloud storage. This aids quick recovery of important documents and data should my system get compromised by malware. I schedule automatic daily backups to ensure minimal loss in case of a malware attack rending files inaccessible.
I store backups disconnected from my computer when not in use to prevent backup contamination if the main system is infected. Offline backups coupled with system imaging enable restoring my computer back into a pre-infection state if impacted by a major virus/ransomware attack.
