Why do you need a good antivirus in 2025?

Nowadays, not having an antivirus is like leaving your front door open when you're not there.The rise of teleworking, online shopping, remote banking, and the use of social media has increased the risk of being attacked. Malware has evolved: it's no longer just annoying; it now steals identities, holds your files for ransom (ransomware), or even acts as a spy for weeks without your knowledge.
