Today's security software keeps out viruses, protects against malware and spyware, and sometimes offers VPN and a password manager. On your computers and laptops, but don't forget your mobile and tablet!
Do you make sure you have regular backups with version history? And make sure your backup software also offers protection against ransomware! Nowadays a virus will first try to disable your security and then your backup will be affected. Use Acronis True Image for a backup with ransomware protection and version history that allows you to restore in an emergency. Finally, the latest version of Windows 10 is the only way to stay safe.
All these products are suitable for iOS or have an app available in the Apple App Store. Because of the closed system of iPhone's and iPad's, spyware and viruses have no chance to infect these mobile devices. Despite the fact that iOS is not sensitive to viruses, installing the app offers many possibilities. Think of an anti-theft module, a back-up module or the parental control functionalities. Functionalities can vary per brand and app.
