VPN (Virtual Private Network)

1. What is a VPN?

A VPN (Virtual Private Network) encrypts your internet traffic and hides your IP address, helping you stay private online and access region-restricted content securely.

Yes, VPNs are legal in most countries, though some restrict or ban their use. Always check local laws before connecting through a VPN service.

Slightly, due to encryption overhead — but reputable VPNs use high-speed servers that minimize this difference.

5. Can I use a VPN on multiple devices?

Antivirus Software

Antivirus software detects, blocks, and removes malware, ransomware, and other online threats that can harm your computer or steal data.
