How can a software firm protect its computers from viruses?

Using antivirus software and periodic scanning is the most effective method for a software firm to protect its computers from viruses. Antivirus software is specifically designed to detect, prevent, and remove malware, including viruses. When installed and updated regularly, it can provide real-time protection against various threats by scanning files and programs for known virus signatures. Periodic scanning enhances this protection by identifying any malicious software that may have been missed or introduced during regular use.

While limiting internet access can reduce exposure to potential threats, it is not a comprehensive solution, as malicious code can be introduced through other means, such as USB drives or email attachments. Utilizing only company-owned devices helps maintain some level of control but does not inherently prevent viruses, especially if those devices are not equipped with proper security measures. Encouraging regular password changes is crucial for protecting user accounts from unauthorized access, but it does not directly address the risk of malware infections on computers.

Therefore, implementing antivirus software and conducting periodic scans is essential for maintaining a robust defense against viruses and ensuring the ongoing security of computing resources.
