Online security software includes firewalls, antivirus, antispam, parental locks, and comprehensive security suites. Each type serves a specific purpose and can be purchased separately or in a package. Choosing the right software is crucial for computer protection. Firewalls prevent files from being sent to or from a computer, while antivirus software includes email filters, spam blocking, and internet security filters. Parental locks can block specific websites, and comprehensive security suites offer all features in one application. Businesses may require more advanced security suites for network security.
There are many different types of online security software. Some are available in a package of more than one type, while others can be purchased or downloaded separately to offer more personalized protection. The software may include firewalls, antivirus software, antispam, comprehensive security suites, and parental locks. Each type is made specifically for a particular purpose, and choosing the right type is key to keeping a computer fully protected.
Firewalls are a type of online security software that prevent certain sites or people from sending files to or from a computer. The simplest of these may be able to block only certain URL addresses, while others can block entire sites based on content. Firewalls can also be installed to protect a computer network, and the price can range from free to very expensive.
Basic antivirus software is another type of online security software. There are generally various aspects to these programs, including built-in firewalls and specified Internet security features. Email filters and spam blocking are common features included, as are Internet security filters that prevent users from accidentally downloading harmful files or viruses onto their computers.
Most computers sold today have some type of built-in antivirus software. A free trial period may be offered, after which the software must be purchased. There are also free versions of these programs online, but features and security may be limited.
Spam blockers can be found both in antivirus software suites and as a standalone feature found in many email hosting companies. While spam is often not a security threat, as it is usually simply unwanted advertising email, most people agree that keeping it out of their inbox is a priority. In some cases, spam emails may contain links to fake websites that may try to steal visitor information or load malicious code onto the visitor’s computer. Host-based spam blockers are usually free and are a bonus for joining a service.
Another type of online security software is parental locks. These can often be downloaded free of charge from the user’s Internet Service Provider (ISP). The effectiveness of these blocks can vary from ISP to ISP and can sometimes be downloaded separately or as part of a security suite. Parental locks can be set up to block specific websites based on URLs or content to prevent children from viewing inappropriate material. Sites can usually be unlocked using a special password.
Comprehensive security suites are the most advanced type of online security software. These can include all the traditional antivirus features, computer scans, email protection, firewall and parental locks, all in one software application. More sophisticated comprehensive security suites can also handle network security, with the more expensive models being used for large companies with hundreds of networked computers. This type of software may not be necessary for a home computer, but it is important for businesses that send and receive large volumes of information on a daily basis.
