Antivirus is software that detects, prevents, and helps you remove malicious programs from your computer or device.
One of antivirus software’s main features is to prevent users from unwillingly downloading or installing malicious programs (commonly called malware). This malware can take many forms, from logging your key presses, stealing information, or taking complete control of the device or connected accounts. Some antivirus software also helps you avoid common scams and social engineering attacks.
How do I choose one?
Some of the best antivirus software for small businesses can be found free or cheap from a range of well regarded providers. Antivirus software is often bundled in to more comprehensive cyber-security suites that can include anti-spam protection, email & file protection, firewalls, and remote management.
Once you’ve found a provider that suits your needs, install the software on every machine that you use for business use. If you use a smartphone for work emails, you may need to find a separate app to install on those devices, or your desktop antivirus will most likely have a companion mobile app.
Am I secure now?
Most antivirus software is set to start up when the computer turns on, so once it’s installed you shouldn’t have to worry about enabling it again. Your antivirus will typically schedule checks to run once a week, day, or month to periodically check that no malicious software has been installed and it will notify you if any is found. It will also offer live protection, which will differ depending on which brand of software you are using. Typically if you are at risk of doing something that will harm your computer, the antivirus will pop up and alert you of it. You will then be given options for actions to take to avoid it.
he other important thing to do is to ensure you antivirus software stays up to date. Most software will auto-update by default, however it is best to check after installation to ensure this is enabled.
