As you probably know, the main objective of security software is to protect and ensure the safety of information, computer systems or computer networks from theft, vandalism, damage, loss and other potential hazards. Of course, security software is not the only solution to protect a computer system, but in my opinion, namely security software plays a crucial role in securing and maintaining the confidentiality of personal computers.
I think the problem is that unlike the corporate computers, personal computers are not adequately protected against Internet threats, since not all users are good professionals in the field of information security, often ignored the rules of computer security and many other security flaws that are not present in corporate networks. And if, in most instances for corporate computers the main threat are insiders, then for personal computers — Network security threats.
As a rule, to protect personal computer against Network threats helps security software, such as antivirus, anti-spam, firewall, anti-spyware and others — as multi-application security suite or standalone software. And despite the fact that this class of programs provides a malware, spyware, phishing, spam and vulnerability protection, they cannot protect against these threats if the user does not comply with the rules of computer security and ignores the recommendations of experts.
