How to prevent virus infections?
- Installing an antivirus - An antivirus software is designed to detect and safely remove malicious software from your computer. These programs scan files, programs, and other data stored on your computer to search for a wide variety of threats that might harm your device.
- Update your stuff - An outdated system or software leaves you vulnerable to ransomware attacks. Updates are important because they often include critical patches to the security holes found in past versions. According to McAfee, in addition to security fixes, software updates can also include new or enhanced features or better compatibility with different devices or applications. They can also improve the stability of your software, and remove outdated features.
- Backup your computer - Your IT security measures wouldn’t be complete without ensuring that your software is regularly updated as new viruses, worms, Trojans, and other malware often exploit outdated applications and software. Another thing to keep in mind is to put a backup measure. Regularly backing-up all of the data in your network ensures that you have copies on-site or in the cloud.
- Educate yourself and your employees - Putting layers upon layers of cybersecurity measures in place should not be the end-all-be-all strategy for your IT security needs. It should be part of a holistic approach to bolster your cybersecurity measures. By ensuring that you are using strong passwords, limiting access to your network, updating your system and software, and educating your employees, you are already strengthening your system’s protection against cyberattacks.
