You should be protected from malware by keeping your software up to date, use strong passwords, and stay clear of email scams. Even if you've complied with all the correct steps, an antivirus program is still required as a safety precaution in the event of a mishap. Selecting the right antivirus depends on your operating system as well as the number of devices you are required to secure and whether you want extra features such as password managers, VPN, dark web monitoring or family protection.

Another important factor to consider is the frequency of updates for antivirus and if it is compatible across different devices.
