I lost my previous laptop to malware and virus. It was my bad. I didn't use the antivirus software. This time I'm going to be extra careful. I plan on buying a paid antivirus solution, perhaps Kaspersky. Apart from that , I would like to know how I can protect my system as I use the internet heavily. I learnt about harness two-factor authentication from this article https://nci.ca/what-can-you-do-to-protect-yourself-from-spyware-malware-and-ransomware/ What do you mean by that and how can I enable that? I don't want my system to be hacked or attacked again. I would like to get your suggestion on this. please help. Thank you for your time.
