Frequently Asked Questions

How do I find the best antivirus for me?

The first thing to do is to understand what you need — all antiviruses come with different internet security tools to help you stay protected, so identifying what level of protection you want will help you figure out which product is right for you.

Some antiviruses have a virtual private network (VPN), some have safe browsing extensions, and some have a password manager. Some only work on certain operating systems, while others cover all operating systems across multiple devices.

It’s important to compare the best antiviruses on the market to find the perfect one with the functionality you need.

What makes an antivirus secure?

A high-quality antivirus suite will detect, flag, and remove viruses and various types of malware. It will also offer real-time protection against all threats, regardless of whether you are browsing the internet, downloading software, shopping online, or opening email. For additional security, many antivirus suites offer a VPN, secure storage, and a password manager — these things all add several layers of protection against various cyber threats.
