Once the computers get infected by the viruses they require antivirus software to clean and disinfect the computer system, thus making sure that they operate normally again.

At times, the damage may be so spread, that even the antivirus may not solve the problem, thus leading to reinstalling and reformatting (Laudon & Laudon, 2009). Antiviruses get mainly suited for small business and medium sized businesses which are under threat of virus attack on the computer networks. Some of the examples of antivirus include McAfee antivirus and Kaspersky antivirus.

Firewall works as, dedicated software which inspects network traffic permitting and denying passage based on the set criteria or rules (Laudon & Laudon, 2009).

The firewall mainly prevents the private network intrusion by unauthorized internet users. Firewall gets suited for medium sized companies and large corporations that hold large customer information and on a network. For the firewall to function, it must be configured properly for its usefulness to be realized.

The antispyware, track data unidentified software, referred to as adware, to damaging software such as keyloggers (Laudon & Laudon, 2009).
