What are computer viruses?

Computer viruses are a long-standing threat to computer systems around the world. Designed to cause harm, damage and irritation to computer users, viruses can perform tasks as arbitrary as opening unwanted programs and as dangerous as stealing personal information and data. Viruses are often developed to replicate themselves and be difficult to track down and delete, which is where Antivirus Software comes into its own.

What is antivirus software?

Antivirus software is a type of computer program which acts as a protection and safeguard against harmful computer viruses. With active protection, the program can detect incoming harmful transmissions and help to nullify or block them before they reach the computer’s core systems. Passive protection also lets the user run scheduled or on-demand scans to perform in-depth sweeps of their hard drive to identify any viruses which have slipped through the net. Antivirus software runs on a database of virus signatures, which help to connect lines of code with individual viruses.

What is a virus signature?

Through research, antivirus software providers assign every virus they discover with its own individual signature. This signature is then transmitted to the antivirus software on customer’s computers – which allows that software to examine the system for this particular signature and eliminate the associated virus. Keeping the signature database updated is imperative to staying protected as new viruses are released on a daily basis and keeping current with the dangerous market can be a full-time job!

How much does antivirus software cost?

Antivirus software is available across a number of price brackets – from entirely free to very expensive! The software itself doesn’t cost anything; it’s the subscription to the all-important database of signatures which costs money. Those paying for antivirus software will be paying a regular bill, normally on an annual basis, which allows them to download the latest updates and keep their computer or device protected from viruses old and new.

Does antivirus software protect me online?

Much of the currently available antivirus software now comes with internet security suites built in, which provides an extra layer of front line protection and stops viruses before they can infect the computer. Other types of online protection include spam filters, anti-malware, anti-spyware, e-mail protection and anti-adware. It’s always worth checking the feature list of every different type of antivirus software to discern whether you are protected during internet browsing.

Can I use multiple instances of antivirus software?

Most antivirus software providers advise against running concurrent programmes on the same system. Whilst the logic that more types of protection stand to identify threats that the others don’t detect makes sense, the way antivirus software works means that clashes of file usage can mean that the instances can block one another’s efforts. Installing new antivirus software should only be performed once any existing protection has been fully removed from the device.

What is the difference between a virus, malware & spyware?

Whilst they are often all collected under the one name, there are some differences between viruses, malware and spyware. A computer virus is a general term which means any program designed to cause damage to a computer – which does indeed include malware and spyware. Specifically, spyware has been developed to monitor the activity of a computer which can then be sold on or used in crimes such as identity fraud. Malware is named for its ‘malicious’ intent – which may be to internally damage the target system, steal information or make unauthorised payments. Whilst there are dedicated protection suites for individual types of computer virus and threats – many antivirus providers have designed full security suites which are capable of dealing with the wealth of malicious code across all formats.

Do Apple computers and Macs need antivirus software?

Absolutely, there is a common misconception that Apple products are immune to computer viruses. Whilst their operating system may be less susceptible to viruses, it is certainly not invincible and there have been multiple viruses released specifically to target OS devices.
