Free VPNs can pose security risks, including potential viruses, especially if the network they connect to is compromised. While VPNs themselves are not inherently unsafe, users must be cautious about the providers they choose, as many free services lack the infrastructure to deliver on their promises and may rent services from unreliable sources. Recent reports highlight that several VPNs claiming to have no data retention actually do log user information, raising concerns about privacy. Both free and paid VPNs can track user activity, but the extent of this tracking depends on the provider's policies and trustworthiness. For users seeking anonymity, alternatives like the TOR Browser may be more suitable, as it was designed for secure browsing and circumventing censorship, although it can also access the Dark Web. Ultimately, users should carefully vet their VPN choices to ensure their online safety and privacy.
