What is an antivirus?

Antivirus is a program that protects your computer from viruses. It scans the files you download and blocks any malicious software before it can infect your system.

How does an antivirus work in a review and comparisonHow does an antivirus work?

Antivirus software works by scanning files and memory for known viruses. It also scans the file system to detect changes that may indicate a virus infection, such as new or modified executable code in an application directory. The antivirus program then removes any infected files from your computer’s hard drive and quarantines them so they cannot infect other computers on your network.

Advantages and Applications

Antivirus software is a program that protects your computer from viruses. It scans the files you download and blocks any malicious programs before they can infect your system.

What are 5 benefits of an antivirus?

  • It protects your computer from viruses, worms and other malware that can steal personal information or damage files on your hard drive.
  • It helps you avoid the embarrassment of having a virus-infected PC at work or school.
  • A good antivirus program will help protect against identity theft by blocking key-loggers and spyware programs that track what you type into your keyboard to capture passwords for online accounts such as email, banking sites and social networking services like Facebook.
  • Antivirus software also blocks adware programs which are used to display unwanted ads in web browsers when surfing the Internet (these ads may be malicious).
  • An effective antivirus solution should include real-time protection so it scans all incoming data packets before they reach their destination – this is especially important if using public Wi-Fi networks where hackers could try to access sensitive data being transmitted over an unsecured connection.

Who should use an antivirus?

Everyone should use an antivirus. It is a good idea to have one installed on your computer, even if you don’t think it needs protection. This way, when you do come across something that could be dangerous or harmful to your system, the software will detect and remove it before any damage can occur.

What types of antivirus are there?

There are two types of antivirus software. One is signature based and the other heuristic/behavioural.

Signature-based antivirus

Signature-based antivirus uses a database that contains signatures for known viruses, worms, Trojans etc., to detect them when they infect your computer or try to send out spam emails from it.

Heuristics/Behavioural antivirus

Heuristics/Behavioural Antivirus detects new threats by analysing their behaviour rather than relying on a pre-defined list of virus definitions (signatures). This type of protection can be more effective against zero day attacks because it does not rely on having an up-to date definition file available before the attack occurs.

For what do I need to look out for when comparing an antivirus?

Product compatibility

You want to make sure that the product is compatible with your operating system and device (if it’s an app).

Extra features

Check if there are any extra features included in the package such as parental controls or anti-theft protection.

If no antivirus is installed hackers can access private information

Support options

See what kind of support options they offer – whether it be via email or live chat. Lastly but not least important is how often does their database get updated? This will ensure that all new threats can be detected by them immediately after being released into the wild!

What makes a good antivirus?

A good antivirus is one that can detect and remove all known viruses, spyware, adware and other malware. It should also be able to block new threats before they infect your computer. The best way to do this is by using a combination of signature-based detection (detecting specific virus patterns) with heuristic or behavioural analysis (looking for suspicious behaviour).
