Three basic ‘dos’ of online security
Frequent features of security software
Remember to ‘be careful out there’ on the net. Security software cannot protect you from all threats but may save the situation should you make a mistake.
Antivirus programs are designed to prevent malicious software from being executed on your computer or smartphone. They can identify dangerous files such as viruses, worms and Trojans by using pattern matching (looking for virus signature strings), heuristic analyses (looking for code that appears harmful) and/or sandboxing (executing the file in an isolated environment and looking for adverse effects).
Spyware is software that collects information for unauthorised parties. Key loggers, which capture passwords and other information that you type, are one form of spyware. Some antivirus programs include spyware protection, but there are also dedicated anti-spyware tools.
Firewalls restrict traffic between your computer or smartphone and the network. They allow authorised access (such as your using email and browsing the Web) while blocking such connections as are not explicitly allowed. One of the most important tasks of a firewall is averting unauthorised inbound connections that may be used to examine your system and exploit vulnerabilities. You should also use a firewall to prevent malicious software from making outbound connections.
Anti-spam software is designed to keep junk email, such as unsolicited commercial email messages and phishing attempts, out of your mailboxes.
As a parent or other guardian, you can use parental control (also called child lock , web filter and Internet filter ) software to manage how children and adolescents can to use a computer or smartphone. For example, you can allow a child to use the device at certain times of the day and for a maximum time each day. You could also prevent children from accessing websites that depict e.g. gambling, horror, smoking and/or violence.
